content: I thought a discussion of the recently released Infiray P2 Pro was warranted as it tells us something about Infiray as a companyThe companyInfiray is a very interesting company as it is not just another “screwdriver” manufacturer of thermal imaging cameras. Infiray and the venerable IRAY are effectively one and the same as they belong to the same owner. IRAY manufacture uncooled microbolometers so their sister company, Infiray, effectively have an in-house source of one of the most important elements of a decent thermal imager…. The Microbolometer FPA. Such a close relationship helps to ensure an Infiray product that can deliver the best performance possible from the microbolometer. How ? well through better understanding of its capabilities and integration needs. I have seen “screwdriver” manufacturers truly mess up a thermal cameras performance through a lack of understanding of the microbolometers integration needs for decent imagery.The productsInfiray produces a decent range of thermal imaging products to match the needs of a large array of end users. They produce both thermal imaging cores for OEM use and finished thermal imaging products for consumers. I have been monitoring the development of products by Infiray and had my first chance to test one of their cores a while ago. I must be honest and admit that I was not expecting much from the Infiray S0 core that I was testing as previous cores coming out of ASIA had exhibited mediocre image quality, with quite high image noise levels. I connected the Infiray S0 core to a Windows PC and awaited the thermal image produced by the windows Software……. After adjusting the focus I was presented with an image that impressed me. The resolution appeared adequate and the image noise levels were excellent when compared to other miniature cores that I had tested. I immediately liked the Infiray S0 coreIt was the core that I had been waiting for in the marketplace…..compact, affordable and good image quality…. plus it offered 25fps frame rate ! My first thoughts were that both FLIR and Seek Thermal now had some serious competition to their Lepton and Mosaic cores. I actually considered the S0 to be a Lepton and Mosaic killer as it offered significant advantages over the USA sourced cores. Infiray had themselves a winner.The S0 is a miniature thermal imaging core with great performance, but it was the size of a Seek Mosaic. The marketplace really needed an even smaller thermal imaging core for integration into all manner of modern devices, both civilian and militaryThink mobile phones and miniature drones. Infiray were clearly up for the challenge and released the Infiray Tiny1-x series of thermal imaging cores. Things were about to get a bit crazy ! This Tiny1-x core was tiny by name “Tiny One”and by nature. It is an amazing feat of engineering, much like that of the FLIR Lepton, and it promises significant advantages over FLIR’s core. Not least of which are higher resolution and decent frame rate. Great for drone use ! The Tiny1 is like an S0 that has been slimmed down to make it a minimalist physical package. It’s small size should not be considered a sign of low performance however. It likely uses the same microbolometer die found in the S0 and has been mounted in a less bulky chassis. The Tiny1 is available in different formats to suit an OEM’s needs. The Tiny1-B is a rectangular PCB with the microbolometer and lens installed at one end. The Tiny1-C is a smaller footprint microbolometer and Lens PCB plus a separate processor PCB. This makes the Tiny1-C a more versatile format for compact deployments. It also has the potential to separate sources of localised heating from the sensitive microbolometer die. Seek Thermal did this with their Mosaic core to separate the microbolometer from the hotter processor components.It will come as absolutely no surprise to hear that the technology developed for the Infiray S0 and Tiny1-x cores has been integrated into the finished thermal imaging camera products that Infiray offer to the marketplace. These finished products offer excellent value for money thermal imaging as a result. The Tiny1-x core technology is to be found in several hand held thermal imaging cameras that come to mind. Guide Sensmart have designed their own miniature thermal imaging cores and these have also found their way into the more budget orientated end of the handheld thermal imaging camera market. Not taking anything away from what Guide Sensmart have achieve with their TIMO series of cores, but the Infiray Tiny1-x is, in my opinion, a superior product.The Infiray P2So what has all of the above got to do with the Infiray P2 Pro mobile phone dongle thermal camera ? Well the last paragraph says it all really. Infiray created the diminutive Tiny1-x thermal imaging core and then included that technology in handheld thermal imaging products. The market for thermal imaging cameras includes those who wish to attach a compact module to their very capable modern mobile phones. We already have the FLIR One, Seek Thermal, Thermal Expert and several other dongle type cameras on the market but it has room to develop. Infiray wanted a piece of that “Dongle” market. The result was the Infiray T2L and it’s variants. That dongle is basically an S0 core in a dongle chassis and very capable it is too. In order to go smaller than the T2L, Infiray looked to their Tiny1-x core series. The Tiny1-x is fixed focus and more compact so it presented the opportunity to create a really small thermal imaging dongle…. And that is what Infiray didThe P2 is so compact that users would be excused for thinking it’s imagery would be poor due to size induced compromises. That is not the case however. Those who tested the P2 have been pleasantly surprised by its imaging capabilities. It looks like we had a new “darling” of the thermal imaging dongle marketplace to consider when buying a mobile phone dongle thermal cameraNow remember that I said the Tiny1-x series are fixed focus. ….. well the focus can be adjusted but not when the core is secured inside a dust tight casing as found with the Infiray P2. I was pleasantly surprised to see the P2 used a large lens protection window in front of the imaging core. It would have been cheaper for Infiray to use a much smaller protection window, as found on the FLIR One series or even no protection window, as we see on many Seek Thermal Mosaic core deployments. Infiray chose to protect the core but that removed access to the cores focus mechanism. Some users desired a closer focus capability than can be easily achieved with a fixed focus camera system. Whilst the P2 may be capable of decent focus at quite short distances, it was not really designed for PCB analysis duties without some help from a close-up lens. The use of ZnSe close-up lenses on thermal cameras is well known and understood on this forum. It has normally been a case of an end user creating their own solution using commonly available CO2 laser ZnSe focussing lenses though. These laser focus lenses are not optimised for such duties, but they do work well. It is not common to see a camera manufacturer offering an add-on close focus lens for consumer grade products. They are offered for some professional grade Industrial cameras, but at horrendous cost ! Infiray have addressed this situation with their new "baby".....The Infiray P2 PROIt is time to introduce the latest offering from Infiray…… the P2 Pro. There has been some “chatter” about this new release from Infiray on this forum and I hope to test this camera in the near future. It offers some interesting advantages over the standard P2 model. The P2 Pro is capable of temperature measurement up to 550 Celsius whereas the P2 was limited to 170 Celsius. This will appeal to those wishing to image the high temperatures found on power electronics or during reflow/soldering operations. The increase in maximum temperature measurement capability is a welcome improvement to the standard P2 specification. That said, 170 Celsius is more than enough for many users of this technology ! Now the interesting bit……… Infiray appear to be a company that monitors users activities in thermal imaging and have chosen to ‘tune’ one of their products to better match the needs of a certain group of users …. namely those of us who use thermal imaging in electronics inspection and analysis. Infiray created a novel add-on close-up lens for the P2 camera series. I was pleasantly surprised to see the very nicely designed close up lens that neatly mounts onto the relatively flat front of the P2 casing using magnets. For me, it was as great to see Infiray deciding to create such a niche, but very useful option for their camera. I strongly suspect that the infiray close-up lens will have better optical performance than the ZnSe laser focus lenses that we often use. This definitely gets afrom me.Reviews of this new P2 Pro model ?The P2 Pro will soon be tested and reviewed by end users so we can expect to see the new models enhanced capabilities being shown on forums, such as this, and Youtube channels, such as Mike’s. I think we are in for a treatSuch a compact camera format lends itself to all manner of deployments. It does not have to be mounted directly on a mobile phone, it can be used with a long USB cable to increase versatility. Mounting on a microscope stand for PCB analysis work would be simpleI own large Android tablets that will happily interface the Infiray P2 Pro so that offers me large screen PCB thermal analysisI suspect Windows PC’s might also be an option for a Host in the future as I was able to use my S0 core based camera with a bespoke Windows 10 thermal analysis program. Infiray may already offer a Windows SDK for their Tiny1-x cores so that might be a path that members of this forum will explore.I can see all manner of 3D printable mounting accessories being created for the diminutive P2/P2 PROWell I have written enough for now. I see the Infiray S0 and Tiny1-x based products being a minor revolution in future thermal imaging. You get a lot of bang for your Buck !Fraser

content: Continuing the discussion of the Infiray P2 and P2 Pro…..If you had such a compact thermal imaging device, what would you use it for ?Uses that come to mind, in no particular order, are :1. Home heating surveys of your home to seal air leaks and improve insulation in these times of increased fuel costs.2. Wildlife and pet observation (I cannot resist thermal imaging my cats)3 PCB thermal analysis for electronics design and repair4. Thermal analysis of a PC to check for hot spots due to poor air movement within the casing5. Artistic photography … this camera is so small that it will not attract attention when out and about in public.6. Automotive maintenance …. searching for faults that present a particular thermal signature. Such as warm fuses due to overload or unexpected current draw when a circuit is supposed to be unpowered.7. Thermography experiments to learn more about thermal imaging and what can effect measurements.8. Electric Solar panel inspection to check for poor connections or failing PV modules.9. Monitoring the temperature of batteries as they are fast charged, looking for cell anomalies.10. Monitoring the temperature of a PCB during a reflow operation.11. Thermal astronomy ? Much would depend upon the availability of a suitable LWIR capable telescope.12. Checking brake disk temperatures on a car to assess braking performance and potentially seized callipers.13. Science experiments to teach children/adults about thermal energy14. Veterinary care - observation of inflamed tissue with elevated temperatures15. Potential Search and Rescue (SAR) operations (within the capabilities of the camera and lens system)16. Thermal Bore-scope for inspecting inaccessible areas17. Monitoring the input and output ports of house radiators to check central heating system balance etc.18. Checking the thermal output of equipment that is in stand-by to see which are drawing significant power when “off”19. Checking soldering iron barrel (oxidised) temperature (a thermocouple at the tip is better though)20. Experiments with resistor wattages vs surface temperature and heat sink effectiveness in electronics21. In a modified form…. Intruder detection using webcam motion detection software22. Passive night vision using thermal signatures rather than traditional starlight or active IR illumination plus a night sight.23. Plumbing - pipe blockage detection & location. Leaking underfloor heating water pipe detection and location.24. Electric under floor heating inspection25. Blood circulation checks on human limbs ( knowledge of techniques required). Cold “digits” may indicate circulatory issues in some circumstances, such as Raynaud’s Disease.26. Illicit use of houses or rooms for growing unusual plant crops under artificial lighting and heatingLocal privacy laws apply !27. Creating a thermal microscope, with a supplemental lens, for biology examination. For example plant thermal distribution whilst growing or Insect wing muscle thermal profiling. Basically examining “bugs” in the thermal domain28. FUN ! Use it for whatever makes you happyAny other suggestions ?

content: Next….. mounting optionsThe P2 and P2 Pro are designed to plug into a mobile phone but such a deployment is not always the best for the task at hand. Some thoughts on alternative mounting options…….1. A bracket holding the P2 camera to the rear of the mobile phone with a short umbilical cable for the data link2. A combined “pistol grip” and bracket holding the P2 camera to the rear of the mobile phone with a short umbilical cable for the data link3. A GoPro compatible mount to permit use of the many GoPro mounting options. A USB umbilical cable can separate camera from Phone/tablet4. An articulated arm + P2 holder for bench working hands free. A USB umbilical cable can separate camera from phone/tablet.5. A microscope type mount and holder for bench working hands free. A USB umbilical cable can separate camera from Phone/tablet6. The combination of a small handheld holder and long USB umbilical cable to permit use of the camera in confined spaces separate from the bulky phone it tablet.7. A holder that incorporates a standard tripod 1/4” x 20Tpi thread for use of photographic mounting options. A USB umbilical cable can separate camera from Phone/tablet8. A protective casing for camera use in harsh environments. A thin Germanium window may be incorporated into the design.9. A mount and lens adapter that permits supplemental lens use for thermal microscopy using reversed thermal camera lenses. (Specialist use)10. A pole mount plus long USB umbilical cable to separate the camera from Phone/tablet. This enables use at heights for building inspection use.11. Drone aircraft mounts (specialist use requiring a suitable Android host system)12. Larger casing format, like a compact camera design, to make hand holding easier. A USB umbilical cable can separate camera from Phone/tablet or the phone can mount on the rear of the larger camera casing. Much like the FOTRIC 200 series cameras.Many/all of these mounting options may be produced via 3D printing. There are already clip on adapters for the P2 in the public domain. Some of these clip on case designs could be adapter for different applications.https://www.thingiverse.com/thing:5420751https://www.thingiverse.com/thing:5482343https://www.thingiverse.com/thing:5339383Any more ideas for mounting options ?

content: Tomasis,For general electronics I would say 120 Celsius is adequate. Anything getting hotter than that had better be designed to cope with high temperatures or it is going to degrade quickly. Many IC’s state 70C maximum long term operating temperature. Ceramic power resistors can operate at high temperatures of ~350C but how often will you come across those in daily life? In such a case, an electrically insulated thermocouple would likely solve the measurement challenge if the thermal camera could not.Have a look at my suggested uses and see how many would likely see temperatures exceeding 120C. The P2 offers 170C which is good and the P2 Pro has the advantage of the low sensitivity mode providing measurement as high as you are ever likely to need at 550C maximum.Fraser

content: Look at the housing RuneHansen created for his T3S dongle camera …..https://www.eevblog.com/forum/thermal-imaging/thermal-imaging-windows-application-for-infiray-t2-t3-thermal-cameras/Lovely designSimilar could be made for the P2 series if a more ‘box’ like design is needed for an application. It is so much easier to install a small camera into a larger enclosure than it is to reduce the size of a large camera to fit inside a smaller enclosure !RuneHansen has also written a Windows application for some Infiray camera models. Maybe the P2/P2 Pro could be added to the compatibility list ?Fraser

content: So you are thinking about buying one of these tiny P2 series thermal dongle cameras but do not have a suitable phone or a phone that you want to use for such an activity, what are the options ?The good news is that the Infiray P2 uses a USB C connector. This is a connector that is not orientation sensitive thanks to its design. This avoids the issue that some users had with mobile phones equipped with micro USB connectors that pointed the wrong way for the dongles use.USB access is nothing to be scared of. If your chosen phone does not have a USB C port, buy one if the many compact adapters that are available or use an umbilical cable that also adapted a USC C connector to a Micro USB connector. If working with a phone that uses micro USB, be aware that accessories that plug into the micro USB port often need to activate the phones OTG Host mode using a OTG activation pin on the port. If using any form of adapter or cable with the phone, it should be one that supports OTG or the phone will not go into Host mode.Owners of Apple products are out of luck as the Infiray P2 does not natively support iOS or Apple products…. But read on, all is not lost !So you have a mobile phone that is either incompatible with the Infiray P2 series or you just do not want to use it with a thermal camera (side loading unapproved software issues for example) What are the options?I faced this situation and found a very affordable solution that works well for me. I went on eBay and bought used phones that would meet my needs and some were very inexpensive as I will explain.If you buy a used mobile phone on eBay, you need to make sure that it works enough to be used as a host fir a thermal camera dongle. If you see ones that do not switch on, have broken displays or are “sold as see”…. walk on ! If however you see a “Spares or Repair” phone that is perfect except for a faulty Phone SIM card port…. It is perfect as a Host to a dongle camera. Wi-Fi may be used for application downloads and file transfers. A USB cable may also be used to transfer image files etc. you likely do not need the phone call functionality for thermal imaging, so take advantage of that fact ! I bought phones with failed earpiece speakers, microphones and SIM card ports that were damaged through attempted use of a SIM card size converter. I also bought phones that were less popular (cheaper) because they were locked to a network. When buying a used phone, do make sure that it is not locked-out through incorrect password attempts or ant-theft countermeasures. Those phones are about as useful as a brick, and for good reason.When buying a host phone for your dongle camera, do consider which models are best suited to your needs in terms of quality processor power, size, battery life and operating system support. Old Android phones with their older Operating Systems will eventually drop out of support and a modern dongle camera may not work with the older operating systems. If you have the option to buy a decent used phone that uses a Type C USB port, no adapters will be needed for direct on phone useI bought all my “Host” phones for less than £30 each, so do not over pay ! Remember what I said, a phone with a fault that only effects the phone cal, side of things, is an excellent candidate for a thermal camera host. It is basically an Android Tablet computer after all !Talking about Android Tablet computers……Remember that the Infiray P2 Series is compatible with Android devices…. That means you can use it with a nice large screen Android tablet computer. I have a few very nice rugged models that I can use and the smallest screen is 7” and the largest 12”It may also be possible to use Android computers or their TV Box variants !The Android App fir the P2 series is side loaded onto the host.If we see decent Windows support by 3rd party software developers, it will open up the host options to include Desktop PC’s, Laptops and Windows Tablet PC’s.

content: lol, I got convinced by Frasiers posts here so I withdraw the order of the uni-t camera and I order P2 series camera to keep my post relevant here. It is a P2 though.Does Infiray sell P2 Pro Macro lens separately? It would be nice.I got some ideas because extension of USB-C cable (why i haven't thought it before).A 3d printed pistol grip with a holder for phone above the grip. Also, a holder for p2 series camera placed behind phone in the middle. So, in overall, it resembles a typical thermal camera.

Some of those Uni-T models are pretty good. The lower resolution ‘a’ versions use a Guide Sensmart TIMO core and are lower resolution than the P2.Fraser

content: Ah yes, the UT690A model. As we have previously discussed on the forum, the UT690A is capable of doing some useful PCB analysis work when combined with a close focus lens to get closer to the PCB. It is, however, close to the minimum useable resolution for such activities and, given the choice, I would elect to buy a higher resolution thermal camera like the P2, even if it meant buying a cheap used mobile phone and constructing a pistol grip holder for the phone/camera combination.Technical spec comparison…..Uni-T UT690ACore: Guide Sensmart “TIMO”Optical Resolution: 120 x 90Pixel count : 10,800Lens FOV: 38 Degrees Horizontal x 50 Degrees Vertical (in Portrait format)Temperature measurement Range: -20C to +400CInfiray P2 (Standard Model)Core: Infiray Tiny1-x technologyOptical Resolution: 256 x 192Pixel count: 49,152 pixelsLens FOV : 56 Degrees horizontal x 42.2 Degrees Vertical (in Landscape format)Temperature measurement range: -20C to +170CAs can be seen, the FOV figures are similar but the P2 has ~4.5 times the number of pixels covering the target area at any given distance. The greater number of pixels for the similar FOV is a significant advantage over the UT690A where PCB analysis or even home thermal survey work is concerned. The 256 x 192 pixel microbolometers are now what I consider “entry level” resolution and replaces 160 x 120 as “entry level” in my opinion. 80 x 60 pixels and 120 x 90 pixels are still better than nothing, but it takes 160 x 120 pixels before the thermal scene becomes easier to interpret without a visible light image overlay.Fraser

content: Thanks to the modern trend of using smart phones for photography and video recording, there are many options for attaching a smart phone to a tripod or pistol grip handle. Choose one that suits your needs and budget ! The P2 is so compact that it woukd easily mount on the rear of the brackets with nothing more sophisticated than Velcro tape. A more sophisticated holder for the P2 could, of course, be designed and made. There is the obvious option to use thecP2 as intended and leave it attached directly to the USB socket at the end of the handle mounted phone.A short OTG compatible cable between the phone and the camera will be required, but such are not hard to find.Fraser

content: Tomasis,Regarding a close-up lens….. I recommend a 20mm diameter lens and suggest two focus distances ~100mm and ~50mm (two lenses and lens holders needed)By using a 20mm diameter lens you use the central lens area and less of the outer, lower performance area.The best choice of lens type would be a meniscus type rather than Bi-Convex or Plano-Convex, but such are not as common cheaply.There are two qualities of ZnSe lens commonly available on eBay…. PVD and CVD. CVD is the better quality lens. The price difference is small in most cases so go for CVD if you can.We have yet to test the Infiray macro lens on the P2 but that lens may well out-perform our simple Plano Convex ZnSe lenses as they are, after all, just repurposed CO2 Laser focus lenses not intended for thermal imaging applications. The AR coating is likely something more appropriate as well.Fraser

content: Thanks Mike,That burn-in protection mode is a great idea. I am surprised that we have not seen this done on thermal cameras previously.The little P2 Pro operating on the end of an extension cable sounds very useful, especially where you might wish to survey the inside of an equipment rack with the phone outside the rack at a comfortable viewing position. Hence my comment on a thermal borescope. We just need a decent thermal image and a compact head assembly. The P2 offers us bothI will be honest and say that dongle type thermal cameras have not been my favourite format since owning the FLIR One G2, G3 and Seek Thermal Classic units. The affordable T2L and P2 are changing my opinion of dongle type thermal cameras though. Versatility is their great advantage over larger “all in one” type camera formatsI am looking forward to your video review of the P2 Pro. I will be producing a written review with various tests and saved images and it will appear on this forumFraser

content: (I had re-post as I did it in wrong thread)Thanks Fraser, good job with the pictures. It gives me some idea what to design. Looks like pistol grip is worth to buy instead of print.I like the idea of modular case you attach either on tripod or microscope stand. Sort of Gopro case but with tripod mount female-screw.The USB connection that sticks outs is fragile, so the case helps, also it would support ZnSe lens attachment.

The Infiray web site provides a direct download link got the App as well so side loading is possible.Mike has stated that his older Samsung Galaxy J5 (Android-6 2016) phone ran the APP but the frame rate was impacted by the phones lack of processing power. This is why I bought used (Circa 2018) Samsung Galaxy A8 and S9+ phones in order to give the P2 Pro camera a fair review with a decent mobile phone host. The S9+ has a powerful processor setBought used, these Circa 2018 phones are very reasonably priced, especially if they have a SIM card port error or other minor fault.The P2 Pro suffers no frame rate issues, that I can see, during a brief test on the Galaxy A8 or S9+. The A8 is running Android 9 (Pie) and the S9+ is running Android 10 (Q).Fraser

Infiray, Guide Sensmart, Dahua and Hikvision are all major players in the new world of affordable thermal imaging technology…..and we have just seen the major player that is Infiray/IRAY effectively banned from participation on the largest, most technical, thermal imaging forum in the WorldSomething seems very “off” with this whole situation to me and I am going off-line to avoid a saying something that I may regret later !What a crap day and there will be 5 forum members not getting a P2 Pro to review thanks to the thread being locked and the OP being banned.

content: I am a relative “Old timer” at 55 years of age so You Tube video creation is not really in my realm of activities. I tend to like studying reviews, associated still images and maybe the odd MP4 video capture. Sometimes You Tube makes absorption of fine details harder for me and if there are no high resolution still images it can be harder to study imaging performance. This is what I said to Infiray when I discussed reviewing their camera with them. They seem to agree that I still have something to offer via a written review that contains lots of nice still images. I can still add video captures to show moving image performance as wellIf I were to be ‘forced’ off this forum I would likely do as Bill_W did and create a specialist forum of my own but I really do not want to go down that path unless forced to. This is normally a friendly place to chat about all things thermal imaging related. Outside this corner of the forum I have recently witnessed some unpleasantries relating to the Test Equipment Anonymous thread and other areas of the forum seem to be getting less friendly than I remember from past visits to them. Could the ‘storm’ outside have somehow found its way into our quiet forum area and Infiray have taken the ‘hit’ as they were in the firing line.I may well be over blowing the incident in my mind, but today I saw, what I consider to be, an aggressive over reaction to a situation by a man I respect. That kinda shocked me. It is his forum though and he can do as he likes with it. Words like “infested” relating to Thermalengineer and Rambo Sonny posts in one thread did seem a little extreme though ! Oh well life goes on.

There is very little information and all reviews I could find are produced by the own company or Youtube videos that also seem sponsored by the brand. The thing is I decompiled the APK and I found libraries from Infisense so probably they use Infiray Core, it also contains what it seems a firmware file called P2-256-V3.03-20220402.bin and the P2 reference made me think if is some sort of rebrand of the same thermal imager.

The main miniature cores coming out of China are from Infiray (S0 and Tiny1-x) and Guide Sensmart (TIMO).The Topdon could easily be using either the Tiny1-x or TIMO 256.

The Tiny1-x series is a fully formed USB camera solution and an OEM just needs to use ID codes in the core to prevent use of their software on other Tiny1-x core based cameras. This is done on the S0 core and its associated software that I have. The OEM can even limit which variant of an Infiray core the host software will work with. This helps OEM's to offer differing products with different capabilities that use the same core hardware and different host software.Fraser

content: Chemart,Thank youI have not tried the Topdon Android App with the P2, but will do so tomorrow.I was hoping for an easy “win” on the a windows software front as such would make the P2 Pro more user friendly when mounted on a desk stand as PCB analyzer.More from me when I find some spare time. I need to start on my review of the standard P2 Pro configuration. I managed to get it working on all four of my Galaxy phones. It even seems to run well on the S5, which is goodTo use it with phones equipped with a micro USB port, it is important to find an adapter that is truly OTG compatible. Many of mine were not ! Once I found an OTG compliant Micro USB to C type adapter, all was wellFraser

content: I kinda mentioned it in my "what do you want this forum to be". But from only skimming across some of the threads there has been at least 3 if not more accounts that acted extremely sketchy while clearly not being impartial users. If they are employees, the marketing/sales team, hired shills or third party resellers that profit of selling through their stores or distributing their *software* in private (Discord) communities - I don't know. But it clearly wasn't declared and that seems strongly disingenuous and as far as I remember against the rules.Without having the admin tools or writing down notes, you have to take any account that says something positive about a certain product or brand for a potential trap. So be careful what you even contribute yourself.I am not against companies participating in this forum or even talking again their own products. But it shouldn't be in this form of faking to be an interested member. The whole giveaway story could have easily ended in 5 people 'winning' that actually are their own people. And the account saying their already have got units to test could be part of their scheme as well. While they likely hand out honest review samples, they also clearly engaged in wrongful conduct, so why trust them. Especially if they try and circumvent being declined."It's easier to beg for forgiveness then ask for permission" is a guiding stance in said jokingly in the filmmaking industry. But in this case it sounds like they asked for permission, got turned down and then lied and misrepresented themselves in an coordinated effort to steer public opinion.So yeah, what are the ethics in tech journalism and how can it be done better?

Is just an hypothesis and I don't own any of this cameras to try, maybe the modules have some firmware signature to avoid burning the firmware of other model.

content: Back on the topic of the P2 Pro....I ordered a simple microscope stand for my P2 Pro as that will ease its use in PCB analysis activities. Now I do not need the P2 Pro for such work as I own a DYT CA-10 and the FLIR ETS320 but I am interested in how the P2 Pro performs in that role when mounted on a stable platform.The microscope stand I bought cost £18.99 from Amazon and I am pleasantly surprised with what arrived today. Let me first say that the stand is made for those torpedo shaped digital microscopes and is built down to an affordable price ! That said, the whole microscope stand is made from aluminium, except for the vertical movement brake and tips of the microscope retaining screws that are nylon. I was surprised to not see cheap plastic used for the vertical adjustment knobs and the locking nut at the columns base. It is better than I expected for less than £20The vertical movement is smooth on my stand and the nylon brake is effective at setting the tension. This stand is not NIKON or Olympus quality, but it does suit the application that we are discussing hereAs stated the stand is intended to hold a digital microscope of diameter up to 35mm. That is clearly not suitable for the diminutive P2 Pro, but the stand is easily adapted to our needs using nothing more sophisticated that a 'bung' to fit the microscope ring and some velcro pads to mount the camera to the 'bung'. It is also possible to make a nice adapter with 3D printing, as has been done for other dongle thermal cameras.I have seen some nice aluminium 'bungs' used with silicone hoses in cars and there is a 35mm diameter size available. I might adapt one of those or 3D print something when I have more spare time. For the moment I will Jerry rig something for my tests.For anyone wanting to buy this microscope stand, here is the Amazon UK page that I bought from but it is also widely available on eBay.https://www.amazon.co.uk/gp/product/B0797PPX8D/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1Price was £18.99, including a nice zipped carry case for it and accessories, delivered next dayFraser

I quickly roughed up such a design but will create a proper 3D printable model shortly. The Cylinder height has yet to be determined as it could be used for added height adjustment below the microscope mounts minimum height setting. It looks like I will be firing up my UP! Box 3D printer again soonIn case anyone is wondering, the mount is also a hard case for the P2 and the camera may be installed backwards to protect the optical window when not in use. It is a nice tripod mount design that has saved me a lot of workI attach the pictures of the tripod mount before I grafted a cylinder onto its rear. I will also print the tripod adapter as originally designed as it will be very useful.Fraser

I love that machineI created a combined holder and cylinder design but then decided to print the two parts separately to facilitate experimentation with the cylinder part without needing to reprint the more complex holder each time. This approach also simplified the supporting structure, as in non was neededThese are just prototype parts but they will work fine for my review tests.

It is just a reduced height cylinder with the required clearance hole for a 1/4" 20TPI camera mount screw in its end plate.I also printed another P2 holder for it. The ball mount was one I had lying around but I think I have smaller ones hiding somewhere and I will likely change to one of those when found.Why build a ball mount for the P2 ? Well why notIt does in fact have its uses. Sometimes you either cannot look directly down on a target or you wish to view the target at an angle to gain thermal information from a different plane. The Ball mount permits angled viewing through 90 degrees, from vertical to horizontal.Fraser

content: I am thinking of making a 'camera on a stick' as well. That would be a P2 adapter and mini ball mount attached to an extending pole plus a long USB cable to a host phone mounted on the handle of the extending pole. That solution would provide the ability to look at targets in false ceiling spaces or similar spaces like plenum chambers in HVAC.Then there is the thermal borescope ! A miniature version of the 'camera on a stick' using the same principe but more compact for accessing challenging areas of car engine compartments of similar cluttered environs.When you have a miniature thermal camera that just needs a USB cable to its host computer/phone, it opens up all manner of deployment optionsIn the above use cases, the fixed focus of the P2 is a distinct advantage over its manual focus T2x series siblings. Focussing a camera that is remote from the user can be a royal pain in the backside.Fraser

I had a word with the Sales manager of the company and he apologised. He confirmed that the individual responsible had acted alone and did not understand the damage he could do to the brand by his actions. He stopped posting here. Sometimes people in a company have great belief in the projects they have worked on and make the mistake of posting lots of positive comments or recommendations for their product. From their point of view it is a double win.... their product sells and people get a decent (in their eyes) product to use. This is where a company needs to have good guidance for their staff regarding advertising products and who may do so. It can easily get out of hand if done incorrectlyI am honestly sorry that Infiray have made a mistake as they have good products to offer the thermal imaging enthusiast. I have permission from Dave to review the P2 Pro and I will review any other cameras I am leant for review, provided it is on my strict terms and the review is kept completely "warts and all" honestNo product is perfect and honest reviews assist companies in improving the next generation of products.More from me soonFraser

I have asked in other threads, but nobody knows if those limitations could be hacked to unleash the full range/full resolution, it will be nice to save some bucks.I don't put prices here because they change constantly, but the VICTOR VC328B and Mileseey TR256i are the cheaper ones (their variants with 160x120 resolution are even cheaper), the others are more expensive with a wide range of prices depending of the seller.

content: I have been asked where I bought my P2 Pro from…… I did not buy my unit, it was sent to me by Infiray free of charge for testing. If buying an Infiray product, I recommend buying from a well known reputable seller who offers quality service and support. Christmas is coming and the scammers will be on the hunt for victims ! I personally would avoid some of the lesser known sellers, especially any offering significant (unrealistic) discounts compared to the average market price. Infiray are not offering deep trade discounts on these units at the moment. I have no connection with Infiray or any sellers of their products so cannot recommend any specific source for these dinky little cameras.Fraser

content: My latest purchase for the P2 Pro (I really am spoiling this camera with accessories) …..I decided to buy a good quality mobile phone holder for use with a tripod or pistol grip. There are many plastic and metal types available but I chose this particular aluminium model because it is well designed and nicely made. I like that it includes cold shoe and 1/4” 20tpi mounting points as this makes it very versatile when using my phone with dongle cameras etc. The tripod mount point offers both sizes of screw mount plus Arca Swiss clamp compatibility. I can either have the P2 Pro mounted on the phones USB socket or mounted on the rear of this phone holder using the 3D printed camera holder and a short USB cable.This mount is not inexpensive at £25 but quality costs and it will last a long timehttps://www.amazon.co.uk/gp/product/B09TPDSLF8/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1Fraser

content: I have tested the P2 Pro with the following phones and it works well with them all …..Samsung Galaxy S5 Circa 2014 - Android 6 (Marshmallow) / UI TouchwizSamsung Galaxy A6 Circa 2018 - Android 10 (Q) / One UI 2.0Samsung Galaxy A8 Circa 2018 - Android 9 (Pie) / One UI 1.0Samsung Galaxy S9+ Circa 2018 - Android 10 (Q) / One UI 2.5The frame rate was fine on all of the above but clearly the S5, being an older phone, may be under greater recessing stress than the later, more powerful phones. Mike has advised that a Circa 2016 J5 worked but the frame rate was impacted. The J5 is not a very powerful phone.The Samsung S9+ was bought with a network connection issue for £79 so was not exactly cheap but I wanted a mobile phone with decent processing power for this, and other tests. An underpowered phone for the P2 Pro test would be unfair to the manufacturer in a review scenario. The A8 is a decent phone with powerful processor and may be purchased at reasonable cost if you look for one with a minor fault. My A8 in “as new” working condition was £65. The A6 is worth consideration as it has a reasonable processor but go for the A8 if the option exists. The S5 is my old workhorse for testing dongle thermal cameras. It had a powerful processor for its day and the FLIR One G2 APP was developed with a Samsung S5 platform considered the ‘standard’. By modern standards the S5 may not be that powerful but my phone did work OK with the P2 Pro once I found a Micro USB to USB type C adapter cable that worked. I cannot recommend the S5 though as she is an old girl and the battery in mine is showing its age. You can likely buy a better used phone for your money now.Fraser

content: This is probably the best app for the P2 I have used yet. None are perfect however.Infiray Goonly has limited editing capabilities after the pictures are taken. No changing the colour palette, adding the scale only adds it in rainbow palette, regardless of the chosen one. If you make a picture with a visual picture-in-picture added it gets lost if you edit the image afterwards.P2 Prohas a better UI but when changing measurement points/lines/rectangles later you get completely wrong values. Also loses any picture-in-pictures upon editing.Uni-T'sThermal mobileprobably has the best UI and even allows overlaying the visual picture instead of putting it into a corner. You can choose opacity and even move the visual picture in regards to the thermal one. Editing later works also, but High, Low and Center point measurements are unfortunately un-toggleable since they are set in the settings and these are inaccessible while editing. No changing the colour palette when editing either.I should note that the current version on the play store (2.1.6) works fine with my P2.I would love to have the option of setting max and min value of the displayed temperature range instead of autorange to make image comparisons with the same range. Seems to be fixed to autorange in all three apps.

content: On another note, I got a P2 with a slightly different case that I can't find any pictures of on the web. The sales listing was P2 and used the usual images with the blue ring and the little ridge along the edges. Mine only has slightly filleted edges and what seems to be a sticker insert with the infiray logo next to the lens. The box label lists "P2" as the model and "IRAIP2A0IR00" as the part number.Edit: All specs seem to be the same otherwise, as expected. A little downside of the case is that, while metal it's either aluminium or some other non-ferromagnetic material. I was hoping of making my own magnet clip-on lenses with the commonly recommended CO2 Laser ZnSe lenses. Basically make the P2 pro accessory myself. Since magnet's won't work I will have to make aliteralclip-on solution instead, like shown somewhere before in this thread.

content: Hmm. So I was just considering getting a Uni-T UTi120M since with the current sales it's almost in "impulse purchase" category. But as always, I started looking if there's anything better and now here were are, I narrowed it down to these options:Uti120m - $150UTi260m - $240P2 Pro - $255I feel like it's between the Uti120 and the P2 Pro. The 260m has more resolution but still a fixed focus lens. But I'm not clear about the P2 Pro. The lens is still fixed focus, just macro, right? Can it at least be removed? I'd like to be able to use it for non-PCB purposes (which I don't do all the time anyway) as well, such as around the house or for car stuff. The descriptions aren't very clear about this.Edit: I see there's also an IniRay T2L with a manual focus lens, but I think I have to set a limit somewhere or I'll be spending $5000 soonEdit 2: Never mind, I found a listing on AE that made it clear there was a detachable magnetic lens so I bit the bullet and ordered it. $200 without VAT, now to just weasel out of that

I picked it mostly because the price different between the options is not huge, and if they make the core then theoretically everything else involved (software and hardware) is likely to be engineered optimally.

content: The P2 (and a 50.8mm focal length PVD ZnSe lens that I held by hand for now) already helped me several times with debugging a tiny short under a QFN chip after soldering as well as see that a prototype board I made became much hotter than anticipated without cooling. (For the latter there is no need for a thermal camera of course)These are two images of said board, made with the uni-t app. The hot square chips you can see are TQFN-32 packages (5x5 mm size). With the 50.8mm lens you can even make out individual tracks in the closeup image. The singular tracks on the right side are about 0.3 mm/12 mil width and the differential tracks on the left side are about 0.2 mm/8mil each with about the same distance between them. Since the lens was held manually in front of the camera the best achievable focus might be even better than shown here.Note how the hot and cold spot measurements have differently oriented text to the center spot measurement and the scale. This is a slight downside with the uni-t app images. I still prefer it over the other apps I've tested so far.Note that this isnotthe P2 Pro closeup lens! I just have a regular P2 and an additional lens I bought.

content: I have been hat of in with my P2 ProBeyond using it just to inspect PCB’s, I have been looking into other uses for this tiny camera dongle. The cameras small size makes it extremely versatile and I can forgive some eliminations in its imaging compared to my much more expensive pro-sumer and professional camerasI cannot thank Bostwickenator enough for designing the tripod mount ‘cube’ for the P2. That 3D printable camera mount has enabled me to attach the tiny P2 to all manner of useful and exotic mounting solutions. I bought various USB C direction adapters and extension cables to provide maximum deployment versatility, and it has been great fun thinking up different ways to deploy the camera. It is the small size of this unit that continues to impress me. It may not be small enough to be called a borescope camera, but add it to a simple ‘selfie stick’ or long camera monopod, and USB C extension cable, and you have a very useful ‘probing’ device for thermal imaging in hard to reach or inaccessible areas. I have a pile of different mounting options on the table for the P2 and I will include details of these in a annex to my P2 Pro review. Just as I did with the DYT CA10 review, I will add plenty of sample images and uses as annexes to the main review. This will demonstrate the versatility of the tiny camera module.My thoughts on the P2 in précis ? Well I have never been a great fan of dongle type thermal cameras and always preferred the ‘all in one’ designs that do not rely on a mobile phone. I can honestly say that the P2 Pro has changed my view of dongle cameras. When made well and made small, they can be very useful tools. The ability to separate the camera head from the viewing device offers advantages over ‘all in one’ camera designs. We live in the real World and miniaturisation of this technology does not come without some compromises. Whilst the P2 Pro performs very well in my use cases, it’s App is a little basic for my tastes and there is some patterning on the image that I am not used to seeing on much more expensive cameras. Does this stop the P2 Pro performing well in many varied thermal imaging scenarios ? I am pleased to say, no it does not. I really like this little camera for what it can offer me above and beyond my larger unitsIf only I could convince my DYT Spectrum Owl 2.0 PCB analysis PC software to recognise it ! We cannot have everything we want thoughTo those who might ask whether the P2 Pro (Tiny1 core) or the T2 series (S0 core) cameras are recommended for them to buy….I say, if you want an affordable thermal,imaging dongle solution, I recommend both camera series. The P2 and P2 Pro definitely deliver decent thermal imaging and fixed focus in a very small package. The T2 series use the larger S0 core that does perform better than the miniature Tiny1 core,. The manual focus will always provide sharper imaging than a fixed focus lens. Manual focus does not suit some use scenarios and can become a drawback, rather than an advantage, if using the camera head remotely from the phone and users easy reach. I make no secret of the fact that that I love the Infiray S0 camera core, and cameras that use it perform well. The DYT CA-10 uses the S0 core. The Tiny1 offers another level of miniaturisation though and it’s smaller lens does reduce performance a little. In the world of miniaturisation, we are always battling physics !Fraser

I'm hoping to get it working on my computer but no luck so far.Interestingly, this Mileseey camera doesn't work with any other Android thermal app intended for Tiny1-c sensors. I read some people were able to use the P2 Pro with apps from other brands, so I was expecting the same to apply to this sensor. I can however use some apps intended for generic endoscope cameras. It shows the splitscreen input directly from the camera, a 160x120 black and white feed showing the thermal image, and a second 160x120 greenscale image showing what I expect is the raw temperature information in each pixel.

I suppose the 160x128 camera has a different USB descriptor and that's why it can't be used with other apps, but have you tried the UNI-T app, it lets you choose the 256 or 160 version when the app is launched.Probably unlocking the higher resolution would need a firmware update as the camera only presents 160x128 resolution.

I was pleasantly surprised by my units image quality and frame rate and thank you for testing the frame rate as that has saved me a jobMy Dianyang CA10 produces a very nice thermal image and that uses the larger Infiray S0 core that is very similar in size and appearance to a Seek Thermal Mosaic core. The S0 offers a larger lens and manual focus and it is to be found in the Infiray T2 series of camera dongles. For me, I would like to own both the P2 and a T2 as they are both strong performers and the fixed focus suits some applications but manual focus provides excellent sharp imaging in other scenarios. I discovered this when comparing my FLIR E4 with my E40….. the manual focus needs of the E40, with associated shallow depth of field, could actually be a bit annoying when imaging targets at differing distances. The fixed focus E4 just provided an acceptable image anywhere in its range of fixed focus, and it has a decent close focus specification. Your video review shows just how easily the P2 may be used for PCB analysis and its close focus without the Macro lens is impressiveLike you I have been using my P2 instead of some of my larger cameras as it is just so convenient. I have lots of thermal cameras to choose from yet I used to grab my E40 (E60) or Hikvision DS-2TP31….. I now reach for the little P2 Pro if needing to do a quick thermal check. For PCB analysis I still use the Infiray S0 cored DYT CA10 (upgraded to CA20 spec) as that offers more capable software that runs on a PC.Fraser

But, if I try to use the P2Pro app, it is asking to turn on the OTG function, strange if it works with the other app.I've tried various Default USB configurations in the developer settings but none seem to make it work.The phone is locked to a particular mobile phone company, would that be an issue?

content: Hey guys... what's the difference between these different models?I've ordered the TOPDON TC001 a few days ago ($175.95 shipped) after doing some research but I couldn't find too much information about it. I can't imagine anything better in the price range and it seems like the Infiray P2 Pro uses the same chip?

content: Something that I found interesting was that the Topdon TC001 Android application has a firmware update function. When I plug in my Mileseey TR160i 160x120 camera, the Topdon app suggests a firmware update for it. I'm hesitant to try it as I don't want to brick my camera from being used with the original app and possibly any app at all. But... The TC001 is a 256x192 camera, so there's a slim chance that depending on what the firmware is for, it could hack my 160x120 camera, which uses the same Tiny1 sensor, to a 256x192 camera.Anyone have any theories on that? I suppose it depends how the Tiny1 is being configured to run in a lower resolution and if the controller/USB interface chip is the same between brands.

If they had areliable/reputable resellersaround the world, some side-by-side comparisons andsome decent softwarethen it should blow the western competition out of the water (or at least get some price reductions). They should get onto that rather than wasting time spamming enthusiast forums and selling direct on AliExpress, the product will sell itself.edit: To add, I bought from the UNI-T store and received one with the silver case and a screen-printed white logo, not the style with the inset logo on a decal.

content: A little update from me….Like Mike, I have been testing the P2 Pro for a few weeks now and I am about to release the review that I have written.Infiray released a new version of the APP on the 6th December and I loaded it today to see if some bugs had been fixed since my testing was completed.To note: My September release of P2 Pro (1.0.5.220921) had some bugs that included …..1. The APP sometimes not seeing the camera dongle and asking for it to be connected. The solution to this was to close down the P2 Pro completely and erase it from the APP history page in Android (three horizontal bar icon on desktop). The P2 Pro APP would then work correctly if manually started or the camera plugged in to initiate an auto run of the APP. I had this issue with the Samsung A6, A8 and S9 Plus phones.2. On the Samsung S9 Plus, when switching to the Wide range (High temperature) mode, the displayed spot temperatures were all over 800 Celsius even when viewing a 20C target. No solution was discovered during testing. The A8 phone did not suffer from this issue.The new release of the P2 Pro APP dated 6 December 2022 has fixed the temperature measurement error in the high temperature range on the Samsung S9 Plus. Sadly a new issue has appeared though. When selecting the P2 Pro APP icon the phone reports that the APP is not installed. Plugging the camera dongle into the phone initiates the starting of the P2 Pro APP and all works normally. Trying to start the APP with the camera plugged in still returns the "APP not found" error. Hopefully a fix will be released soon. This fault is present on my Samsung A6, A8, S9 and also my Motorola G5 so it is not a “Samsung issue”.I have yet to test the new release properly but it still appears to have the issue of not always seeing the camera dongle and needing the history entry to be deleted before it will work again.Fraser

I'm getting rather frustrated with this device - it seems extremely picky about which devices it will run on at all, it doesn't work on my Motorola smartphone, I tried a Xiaomi from a friend and it wouldn't run either (just stuck at the OTG screen). I've now got a Samsung tablet and it shows an image for a second or two, then just hangs (until restarting the app, at which point it shows a picture again for a second).Connecting it to a Windows computer it works just fine (with the occasional stutter in the framerate, however), but that's not exactly how I imagined using this.

content: I've found pretty severe JPEG compression artifacts affect the images captured from the P2 Pro using the "P2 Pro" app from the google play store. Does anyone have a recommendation for alternative android-based software, or a setting I've missed in the "P2 Pro" app? I'd get better image quality if I took a screenshot via the OS, as compared to using the built-in image capture. Toggling the "Improve image quality" setting doesn't appear to affect anything.The resolution is fine, the images come out at around 350kB, 1440x1080x24, but the image quality is pretty ragged. It's especially obvious around the overlay text, there is a fuzziness about it that has nothing to do with the comparatively low-res thermal sensor.

content: tjhowse,I agree, the images that are saved do not do justice to those seen on the phones display as a live image. Sadly the are no options for the user to change compressions levels in the P2 Pro App. The image quality control acts on the algorithm that is in the image processing algorithm and not the image save process. I saw little difference between the image quality enhancement being on or off.There are other APP that work with the P2 Pro as, thankfully, the Tiny1 core is used in several other cameras.If the Vid and PId are the same, the other manufacturers software will often work with ten P2 Pro and even supports the high temperature range.Take a look at the TOPDON TC001. It has Android and Windows software that may be downloaded from the TOPDON web site. Sadly the Uni-T UTi720M app will not recognise my P2 Pro which is a pity. Infiray have another Android App called “Go” that was for the P2 standard model but it still has the Pro option switch. I suspect saved image compression will be the same however.It would be good to identify sources of alternative Apps for the P2 Pro so that the best ones may be used for a particular application.Fraser

But yes, cost a little bit more. Are they so new that this hasn't come up yet? Or they a bit older already?Speaking of T3/T2, I suppose the biggest differences between the T and the P series is the target market? T for 'outdoorsy things' and P for professional use? Idk. I see that the T's are sold in kit form with one of those 'gun-type' holders, though on ali express that doesn't seem to be the case?So am I missing something obvious, or is this discussion entirely price driven? Or do we wait for a P3pro :pP.S. just noticed that on AE they also now list an iOS version, for those that care

content: So pardon my ignoranceSo T is FPGA, and P is ASIC, which could explain why the P2 is cheaper, FPGA's cost a lot. In theory, more functionality could be added to the T (if the development gods will it) and the FPGA variant _could_ be more powerful/feature rich in general I recon?Anyway, So the sensor is about 50% more expensive and older, but at a higher resolution. There's no P3 only the T3, so would it make sense to hope that a P3 would be released somewhere this year? Or is the P2 'really more then good enough'. Higher res sure sounds nice, if all other things are equal. Heck If it'd take to long, might still try to get a T3 still...

Different drivers provide different functionality. The ASIC (rather than PID number) driver provided the greatest number of options for fine tuning the core. Anyone wanting the windows SDK should contact Infiray and not me please.I have tested the TOPDON APP with my Infiray P2 and it works fine. The TOPDON and P2 both have the same 5830 PID. The UNi-T APP did not work with the P2 PRO even though their 720M/721M camera uses the Tiny1 core.Fraser

Right now its happy to stream on motioneye installed on a pi3 but I'd like to get rid of the raw image and be able to use at least a grayscale palette. I'm thinking that it's going to involve processing the image and then getting that into motioneye instead of motioneye directly. I'll also mention that this isn't a p2 but a tiny1 core pulled from a sketchy camera but it does support UVC as is and shows as the generic realtek usb cam.

I've moved it slowly across hard-edged objects parallel to the crack and haven't seen any odd artifacts. I tested blocking the front and found that the lens behind the cover is a small portion of it. So as a repair I put a tiny piece of Scotch tape in the corner over the cracks, to keep them from worsening. It's held up for a few weeks now being used daily.Next step is to contact the site I ordered from (Pergear) and then Infiray and see if they can send me a new cover piece (I guess it glues in? I've seen the teardown video where there's a washer-looking thing below it). Maybe it just needs a new shell. The card I purchased it with actually includes insurance for accidental damage like this though I'd need a repair estimate. I'm not keen on shipping this off to China to be maybe repaired, maybe damaged.Just thought I'd offer some warning to be careful with theirs. I'm still LOVING this thing.

content: It seems there is interest in using the P2 Pro as a USB camera on PC and interpreting the content of the video stream, so I will share the experiments I made after receiving mine.Basically I played with ffmpeg to extract raw data from the video stream.The main finding is that the USB UVC device is exporting 2 video streams- a 256x192 yuyv422 stream that contains a grayscale 8 bits normalized video that is directly exploitable (the 8 bits luminance channel is the temperature data and both chrominance channels are fixed values to give a colorless/grayscale result)- a 256x384 yuyv422 stream that contains an exact copy of the previous stream in the upper half of the image and a greenish picture in the bottom half. This greenish picture is actually the raw non-normalized sensor values that are actually encoded in gray16le format (just 16 bits per pixel, in one grayscale channel, little-endian).Examples playing with those video streams on a linux box:Code:# First of, find the device corresponding to your IR camerav4l2-ctl --list-devicesCode:# Check that the normalized stream works fineffplay -input_format yuyv422 -video_size 256x192 -i /dev/video4Code:# Look a the combined streamsffplay -input_format yuyv422 -video_size 256x384 -i /dev/video4Code:# Use ffmpeg to grab the combined stream, crop to keep only the bottom half# then pipe the raw data to ffplay and reinterpret it as gray16le.# The resulting picture will be almost uniform gray due to the low range of# the raw values in the 16 bits dynamic range.# The raw values in a 0°C to 100°C environment ranges around 19000 to 24000# (in a 0 to 65535 dynamic range).ffmpeg -input_format yuyv422 -video_size 256x384 -i /dev/video4 -vf 'crop=h=(ih/2):y=(ih/2)' -pix_fmt yuyv422 -f rawvideo - | ffplay -pixel_format gray16le -video_size 256x192 -f rawvideo -i -Code:# To make the resulting raw stream more useful, you can add a normalization filter# followed by a pseudocolor filter with typical IR camera colorsffmpeg -input_format yuyv422 -video_size 256x384 -i /dev/video4 -vf 'crop=h=(ih/2):y=(ih/2)' -pix_fmt yuyv422 -f rawvideo - | ffplay -pixel_format gray16le -video_size 256x192 -f rawvideo -i - -vf 'normalize=smoothing=10, format=pix_fmts=rgb48, pseudocolor=p=inferno'Code:# You can then play with pretty much infinitely long ffmpeg command lines# For example, you can upscale the video stream, display the min and max raw# values in the top left corner and add a time graph of the min and max values# at the bottomffmpeg -input_format yuyv422 -video_size 256x384 -i /dev/video4 -vf 'crop=h=(ih/2):y=(ih/2)' -pix_fmt yuyv422 -f rawvideo - | ffplay -pixel_format gray16le -video_size 256x192 -f rawvideo -i - -vf 'signalstats, split ;  normalize=smoothing=10, format=pix_fmts=rgb48, pseudocolor=p=inferno, scale=w=2*iw:h=2*ih, drawtext=x=3:y=3:borderw=1:bordercolor=white:fontfile=FreeSerif.ttf:text=MIN\\: %{metadata\\:lavfi.signalstats.YMIN} MAX\\: %{metadata\\:lavfi.signalstats.YMAX} ;  drawgraph=m1=lavfi.signalstats.YMIN:fg1=0xFFFF9040:m2=lavfi.signalstats.YMAX:fg2=0xFF0000FF:bg=0x303030:min=18500:max=24500:slide=scroll:size=512x64 ;  vstack'So the raw data from the sensor are very easily accessible. The only missing part is the conversion from raw values to actual temperatures. I don't know if some kind of calibration needs to be applied or if the raw values can be converted directly to temperatures with a simple fixed (linear ?) equation.In my quick tests I derived the following equation to convert raw to °C but this is only a rough guesstimate: f(x) = (x - 19295) / 51.2857

content: very nice!Not sure if ffmpeg is good option for extracting frames in real-time, because of performance reasons.I tried using the "libuvc" library to access the camera, but apparently it does not work on MacOS > 12, because Apple now takes exclusive access of cameras, and apps need to ask for permissions, which is another hassle.But if there is no need for the extra metadata to generate the thermal image, then it should be possible to do it with the browser media Api + canvas.For temperature reading, we need the metadata because the colors are not directly mapped to a temperature. That equation needs at least another variable for determining the range, like max temp value

I added a final .txt just in case Bin isn't allowed.2) it seems to me that the InfiRay Go App is the only one that not only saves the images but also saves (but I don't know where) the temperature values or the raw values of the entire matrix, because from its gallery, with the "edit" option the image without overlays appears and you can work on it exactly as in the shooting phase. This option on my smartphone does not work with any other compatible app. I find it extremely useful. I have not been able to find where this data is stored - does anyone have a chance to check?3) Rune Hansenhttps://discord.gg/R95eer5khas announced its intention to support P2 Pro in the new version of its wonderful software soon!Thanks for your attention and good work!

(e.g. video format, temperature conversion and the out-of-band communication and format of the USB vendor requests, like setting the color palettes, shutter control, high temperature mode, etc)Some of it has also already been found out by others in this thread, as I've just discovered.I plan on publishing a write-up of everything I've found later on too, but for now I'm focussing on getting a basic Python implementation working.Here's also a Mastodon thread about my progress, if you want to keep up-to-date in the meantime:https://chaos.social/@LeoDJ/109633033381602083Quote from: aurel on January 28, 2023, 12:29:05 amAccording to my reverse engineering the lower video frame contains the temperature data directly in Kelvin. It's 14-bit, shifted into the most significant bits, multiplied by a factor of 16.So to get from the value from the camera to a temperature in °C, the formula is:Code:t = ((x >> 2) / 16) - 273.15or simpler:Code:t = x / 64 - 273.15

content: Hi. I need the advice of experienced thermal imager users. Because of the cheap price, I bought myself a Victor 328B thermal imager. As far as I understand, its filling is similar to the P2 PRO. In the evening, I indulged them in the P2 PRO app from Infraray. At first glance, it worked fine. But the next day I noticed that it began to show the wrong temperature. Moreover, in the application from Infraray it has a room temperature of hundreds of degrees, and in the application from the manufacturer a negative temperature at a real temperature of about 20 degrees. Judging by the sound, calibration is performed every 5-10 seconds. At the same time, it seemed to me that after warming up, calibration becomes much less frequent. Do you have any advice on this situation?

content: In such a situation I would delete both Apps (Victor and Infiray) and reinstall, just the Victor App. Test the camera again for correct operation. It is unlikely that the Infiray App will damage your camera, but it is possible for an App to corrupt another Apps driver.A high temperature reading error was a bug in one version of the a Infiray App whilst it was set to the high temperature range. That bug was fixed in a later release though.FFC flag events decrease in frequency once the cameras microbolometer has stabilised at its nominal operating temperature.Fraser

If they can replace the window or housing and sell it as refurbished, they've made money, albeit a small sum, with very little effort. My point being, did they see an opportunity to barely profit and appear to have amazing customer service? I can't help wonder what they would do in other cases if it weren't an easy fix.

content: The window can be Germanium or Chalcogenide IR glass. In some cases, very thin Silicon windows may be used. Silicon is not good at LWIR wavelengths so it has to be very thin and the cameras calibration has to take account of the transmission loss. A suitably AR coated window in eitherGermanium or Chalcogenide IR glass materials would cost as much, or more than, you are being asked to pay. The supplier is, in my opinion, being very fair to you.The camera does not need that window to function but it’s calibration might be slightly off without it. Buying a generic window of different transmission figure would also mildly effect measurement accuracy.Fraser

Interestingly the Topcon app looks virtually bang on, Anyone come across this on the P2Pro app as well, I have tried the Sliders for room temp and distance but tbh its not solving it.

content: Hi! I've made a native C++ app for the Topdon TC-001 and the Infiray P2. It runs smooth on a Raspi4B, and of course on a PC.It just displays the video (with fixed temperature range), and can record video, that's all for now. I'll see what I can do with it.I do only own a TC-001 (it is a bit cheaper than the P2) This should work on a P2 and similar cameras that uses the mentioned earlier 16 bpp thermal raw format.Thanks to all for the info provided on this thread.It is only for Linux for now. The requirements are libv4l2 and OpenCV so it could be built for other systems.Code and documentation are here:https://github.com/yomboprime/yombirThe only quirk is that I only use the v4l video stream, I don't set any parameters via USB. I think that for this reason the camera sometimes readjusts the range or the optics by itself, making an audible clic and stopping the video for a second. I should read more deeply the code at the @LeoDJ 's repository.The app displays the colored image in fullscreen and you can toggle recording by pressing enter. Press spacebar to exit.There is a script to later convert (offline) the recorded raw files to colored .mp4 videos (optionally upscaled with linear interpolation)(More info is in the README)The second video I recorded:https://youtu.be/NDmfXmaBHv4Attached is a test image.Greetings

content: I have noticed that the camera develops a "significant" gradient when warming up. In case of my P2 Pro the "left" of the image becomes offset warmer and warmer over time but once it has reached thermal equlibrium and does not get any warmer, simply restarting the app (and there by triggering the shutter self correction) fixes the issue.I wonder if the P2 Pro has an internal thermal sensor that could detect the thermals changing and reissues a self cal or at least promt the user about the issue.On a side note: I also notices that setting the scale range manually in the P2 Pro app, does not actually expand the full color pallet to the selected range but just crops away the parts above and below, which is kind of stupid and does not increase the usable thermal resolution at all.

It was a really nice review you did of the P2 ProI have a bit of trouble to decide between the T2S+ and the P2 Pro. They are currently very similar in price.Perceived cons/pros of the P2 Pro:+ Very small+ Very large depth of field with fixed focus. (20cm to infinity according to Frasers review)- Needs fixed macro lens for closer than 20cm inspection- Fixed macro lens has shallow depth of field at appx 25mm.- No hard case included- P2 Pro App is crashy and glitchy according to reviewsPerceived cons/pros of the T2S+:+ Included hard case+ Built-in variable focus macro lens capable of focusing to ~1cm according to some reviews on youtube+ Included pistol grip (not really sure, I want to use it though...)+ May have slightly better image quality than P2 Pro due to the S0 core?? (according to Fraser - no comparison seen)- Variable focus lens may have shallower depth of field for more general use >20cm ?? (No info found)- Slightly chunkier case than the P2 Pro- Slightly less maximum temperature span than the P2 Pro (450C versus 550C)- Xtherm app is perhaps even less functional than the P2 Pro app?Hope someone can enlighten me a bit

The T2S+ has a wide temperature range, while the T2L has two smaller ranges, which can be inconvenient. Apart from that and a slight difference in measurement accuracy, they are essentially the same.I am not aware of a better thermal camera than T2S+ (for electronics) even within the $1000 price range currently. And this is for about $300-25fps-adjustable focus-adequate resolution-low noise-wide temperature range-PC appsWhat more could one ask for?

The phone support the OTG function according to the speification. Unfortunately the manual switch mode of OTG is removed from the settings menu, Android should recognize the attached device and switched the OTG mode automatically.Tomorrow I will have a canche to try the camera with a Samsung S7 - Android 13 patched - with an OTG supported USB-C to USB-micro converter. I am a bit sceptical about this test because the Android 13 settings has no manual OTG switching as well, it is automatic. Plus the converter could be a problem as well. We will see.Hope you have some information how to proceed forward on this,Regards,Mihaly

content: Sadly this is a risk with buying Thermal Dongle format thermal cameras. Unlike designing for an iOS phone, a manufacturer has to design for a very variable environment that is the Android phone ecosystem. The hardware can vary greatly and there are many versions and variants of the operating system in use. This makes it very hard to ensure that a dongle camera will work with all phones and equally well across a large range of phone specifications. FLIR designed their Android FLIR One G2 to operate well with a Samsung S5 model that was a current performance model. They told me that it was a real challenge to design a camera that would work with a range of hardware platforms and they used the Samsung S5 as a reference phone. They even admitted that they found it hard to get the performance of the FLIR One G2 equal to that of the iOS version as software fine tuning was more restricted in order to maintain broad platform compatibility.Fraser

content: I just found out that the raw data of the P2 Pro seems to be embedded in the jpeg file. When you open a P2 pro jpg file in the digikam desktop app, the metadata panel on the right shows you the overview of the extra information in the ExifTool tab. The actual raw data seems to be in the APP3 segment (never heard of the APP segments before...). I have attached sample metadata copied from digikam that does not include the real binary raw image data block. I have tried to extract the raw data with Exiftool but only managed to get a formatted dump of all metadata using the -v5 option. There is also a thread on the exiftool forum where a similar situation for a DJI thermal camera is discussed:https://exiftool.org/forum/index.php?topic=11401.msg61816#msg61816I really like the camera but the software kinda sucks. Extracting the raw data and making your own plots and analysis would improve the situation.

This image does not change when you edit it in phone app and save it, so I assume it is the temp data. The temperature scaling is unclear to me and I found no scaling factors in the exif metadata.It looks like the original app is unclear about the scaling as well! The extreme case is when you edit an image recorded with the high T range (550C max). Then the edited image shows a temperature more than twice as low as temp show during recording... I found substantial differences also for images recorded in the high res/low T mode.python test code:Code:from PIL import Imageimport numpy as npimport matplotlib.pyplot as plt# The APP3 block is 294912 bytes in size# This corresponds to 6bytes/pixel for a sensor size of 256*192# 256*192 = 49152 = 0xC000# 294912/256/6 = 192# 65532*4 + 32784 = 294912im = Image.open("cold.JPG")# concatenate APP3 chunks of data.

content: Hello,I got myself a P2 Pro a few days ago and had some time playing with it connected to a windows PC. Here are some of my findings and issues:The P2 Pro is usually installed as a simple USB video device, which can be accessed via any software that can handle a webcam. In this mode, the cam shows a YUY2 formatted 256x192 gray-scale image and, if you can configure the software to use the second possible frame format (256x384) the lower half of the frame contains the raw data. Just like the one of @PaulDamian, my P2 Pro Hardware has the VID: 0BDA and the PID: 5830, which means that most of the usual Tiny1C drivers cannot be installed, because they expect a PID of 5840. That said, my P2 Pro does not work with any of the usual PCXthermDemo-based windows tools. Most of them are able to detect the camera, but as soon as they try to trigger advanced functionality like the gain mode or any shutter related functionality, they just crash instantaneously. This is most likely because the PID 5830 P2 Pro with the default usbvideo driver does not seem to be capable of executing the respective usb commands. Forcing one of the Tiny1C drivers to be installed for the P2 Pro can be done, but then the P2 Pro does no longer work in webcam mode and also cannot be detected by any PCXthermDemo-based windows tools. This is most likely because they expect a device PID of 5840 in this case.The only tool that worked out of the box but offered no advanced calibration and shutter features in its trial version was the IRCAM Thermal Viewer which can be found in the Microsoft app store.After analyzing the P2 Pro app, which works with my camera, I discovered that it most likely accesses the camera by using the libuvc and libusb-1.0 libraries. So I put together a little c++ program to access the camera, but it did not work until I replaced the default usbvideo driver in windows with a libusbK driver using the Zadig tool. This also killed the ability of the cam to be used as a webcam, but after replacing the driver, I was able to get images via libuvc, extract the lower RAW data part of the image and convert the contained 14 bit data by normalizing the image, rescaling it to 8 bit and doing some sharpening, resizing and color mapping. It is worth mentioning that the obtained image looked good, but not as sharp as the P2 Pro's own gray-scale image in the upper part of the frame, which seemed to be sharper and produced better contrasts in darker areas.Until now, I have found no way to change the sensor range, activate the sensor protection or activate a NUC function on my P2 Pro (does it even have shutter control?). The latter would be especially useful, since the P2 Pro has a pronounced noise pattern, which becomes very visible in the image when rotating the camera. I also discovered a seemingly sensor temperature dependent blotch in the lower left corner of the images of my P2 Pro that seems like there is kind of a spec on the sensor or the internal lens (see attached images). It is very subtle when starting the camera in a cold state, but gets more and more pronounced as the camera temperature is rising after a few minutes. I am pretty sure this blotch was not there during the first two days of use and it is also visible in the RAW data portion of the images(the green part with the inadequate YUY2 conversion). Has anybody else spotted something like that on their P2 Pro? Or maybe it is a sensor defect and I should get my P2 Pro replaced?

The periodic NUC calibration is necessary to account for the changing sensor and device temperature. After a cold start of the camera, you can actually see a non-NUC corrected image before the first shutter click.

Videos come out looking like this no matter what I do. I'm not sure if it makes sense to keep the P2 Pro if I have to rely on old versions of the wrong app continuing to work in Android. It would be a bummer to lose the macro lens, but there are somewhat more expensive standalone products, as well as the TC001 of course.

The same can be also seen with the ffmpeg command shown above (white line on top).The other obvious issue is the clipping/noise (you can clearly see it in the image, around the fingers). Those clipping patterns/areas are also visible in the greenish wrongly-parsed preview as well, exactly in the same positions but more pronounced.I am just getting the bottom half of the stream, treating it as 2-bytes per pixel, little endian and that's it. In code I also tried to do some linear AGC scaling but the clipping/noise areas are still there. They do change on each calibration (shutter cycle of the camera)Any help? I'm I missing something, is there some further processing that has to be done? (Thanks!)It looks like the issue is with ffmpeg. Somehow it messes-up the data, not giving actual raw values (or maybe the options I pass are not correct). With opencv I'm able to get proper data.

content: Attention there... that Sharp Infrared Analyzer 0.6.3 file is ringing every virus scanner bell available in this part of germany.Aside from that, from Windows 7/10/11, I found that a quite reliable way to get data from the P2 Pro is by installing libusbK with zadig and then use libusb to get the image data. I am also digging my way to get a solution working that includes the command interface. For this, I contacted the surprisingly good customer support at Infiray and got two seemingly beta state SDK compilations. The older one has all the code for the command interface and the newer one is encapsulating that in a separate lib with no source available, but with a better usable set of interface functions. The SDK is a modified version of libuvc and among other things adds still image support and the command interface. The catch is: the current state does not work out of the box, but needs some bug fixing. Apart form one bug in the startup code or the resource management, which temporarily locks up the camera, I managed to solve the issues and communicated the solutions back to Infiray. In contrast to what everyone in the "IRCAM Thermal Viewer" bubble is willing to communicate, the command interface is no longer a repurposed UVC standard function for setting the absolute zoom that is fed with some 4-digit hexadecimal commands. Instead, the RTS5840/5830 chip is used to relay I2C commands to the Tiny1C IR assembly. Once I get this working, I will forward the solution to Infiray, to make it available for everyone for free. Until now, they seemed pretty motivated to make the P2 Pro a great experience for everyone.

The pull request adds commands for shutter control, basic NUC calibration (against shutter or background), and gain switching. There are additional Windows(7/10/11) specific add-ons for that in my fork of the project (https://github.com/Pinoerkel/P2Pro-Viewer), including a little command interface. Because this uses OpenCV, it should work without additional drivers in Windows, and with minor changes in LINUX as christosnc confirmed.

I tested the versions available on apkpure and the last one that works and is available as an apk (and not apkx) is the Mai 31 version (2.00.003).Unfortunately the original P2pro app is utterly garbage when it comes to measurements. The point and rectangle measurements and the provided statistics are obviously not correct while the topdon app gives reasonable values. Things get much worse when one tries to analyse existing images. Then the measurement data is completely useless. Also a recent update of the infiray app did not change anything in this respect. If had known this before I would have choosen the topdon or some other camera instead.

It gave readings for the houses wall of -30C and the window region of -10C! I checked both the p2pro and the topdon app - same result. Then I tried to measure the freezer (inside the house) with its door open. This should be somewhere around -18C. Also getting -30C here. While the temp readings are wrong, I still get a good image contrast, so the problem seems to be in the conversion function and not the sensor itself. Finally I did a series of measurements warming up a cup of cold water, starting at 1C. See the results in the table below. Clearly the error increases drastically towards 0C. Maybe infiray did confuse 0C vs 0K as the absolute zero.... Anything seems possible.

content: Well, I think the major problem here is physics. At low temperatures the IR emission is low and the reflected radiation becomes the dominant factor. I just tried to take a look in my freezer - the numbers are all over the place despite I think everything there is relatively the same temperature. Why? because different materials reflect & emit IR at different rates. Ideally, you should use proper emission values in the sensor setting when you take measures of a specific material. And because the emission depends on temperature exponentially this is crucial at low temperatures. So technically I think the low-temperature limit of the device is just a temperature where errors become too much. Maybe you can have more-or-less good results at -10C but you MUST calibrate for material in this range while in +20C it is not that critical.

content: all valid arguments but I think this does not explain the wrong temperature readings. Consider the outside experiment for example. There the whole environment (all heat sources except my body) was around -1C and the window areas a little warmer. No reason here to show -30C. For the open freezer the temperature should be higher if there was much reflection from heat sources around it and not lower.

content: Quote from: ksxx on January 07, 2024, 11:54:09 amFWIW, I have the Topdon TC001 (which supposedly uses the same internals as the P2 Pro) and wrote my own C/C++ app based from Les Wright's Python script.https://github.com/92es/Thermal-Camera-ReduxWhen I tested it on my frozen goods, it measured the same as my freezer thermometer. Granted, neither are lab grade, but both were in sync.The app is free and you are welcome to see if it performs any better than the OEM app. It has already been run on a P2 Pro.Also, if you have a known delta curve, I could add an optional calibration filter to the app, similar to microphone calibration filters.

content: Quote from: G28 on January 11, 2024, 04:59:24 pmLooks like cool a app - thank you! Since I am on windows and have no real hardware Linux box around I cannot test it at the moment (and I dont know how to compile it on windows). However this triggered me to look at the older python code and I tried to get it to work for me. The simple linear temperature conversion posted here in this thread earlier works well, but again I see the same temperature error at low temperatures as with the manufacturer apps. Looks like both the topdon and the infiray app display the normal (upper) video stream as an image. This image looks ok and has contrast also for cold objects. The raw stream (lower half) clips to -30.2C for everything below ~0C and is completely featureless in the cold areas.If my camera is not an exception, this may point to an internal problem of the Infiray models but I have to do some more testing here. It would be nice if someone with a P2Pro could test their camera on frozen objects to clarify this issue.stripped down python code to stream video from the cam and temperature conversion here (using the cv2 package)https://gist.github.com/ks00x/af520dbba1ada0fbdc5e5d6582b22e55#file-p2prolive-py-L10

The upper half of the image is the normal picture from the app and a line profile cutting the pizza in the center. The values in the graph have no physical meaning. The lower part shows the temperature data extracted from the raw data in the file. The line profile values are in deg C. I did measure with an infrared thermometer as a reference and the plastic wrap at the right side of the pizza was ~ -4C and the unwrapped part was ~ -12C. The temperature in the exposed pizza area is totally clipped to -30C. That is also what the native app shows in this area.

I used black electrical tape as it has good emissivity. I then stuck the block & probes into the freezer and let it soak for an hour or so. After a while the 2 identical probes were within .1F of each other. I then put the block under the P2 Pro, wiped the condensation off the tape and took the following pictures.After 15-20 min the block had warmed up to ~40F, the 2 probes were still within a degree or 2 of the P2 Pro.This is using G28's software.

content: Yes, the P2 Pro tracks my thermocouples well, the setup wasn't perfect but the probes were in as intimate contact with the aluminum block as I could manage, the electrical tape was as good a black body as I could find. I would have liked to get the block colder. It actually warmed up from about 6F to 13F in the 2-3 minutes it took to get from the freezer to my lab setup. I wiped the condensation off the tape without touching it with anything other than the wipe so as to not add any heat to the tape. In the picture you can see that the tape that is not in contact with the block is slightly warmer than the tape the measurement is taken from.Right now the P2 Pro is measuring 66.4F and the thermocouples 64.6F and 64.4F.The setup has been running continuously for over 2 hours.

I've read about a lot of problems with the app, but on my samsung a52s works flawlessy.I was worried about the lack of fusion mode of this type of camera, but the resolution and sensitivity is so high that i not feel the need of it. The macro lens allow crazy detailed photos of really small things.The only thing that i not like too much is the compression used for the photos. The realtime image is much more detailed. I would love to have the ability to choose the compression level, or eventually get uncompressed images.I know that they made some crappy marketing, but the product seem quite good, and compared to the other ir cameras that i have, is waaay better. And it's incredible as it's so small.I was unsure if get the uni-t 260/271 or this one, that must be almost the same thing... i wanted a portable device with the macro lens, and i not liked the "gun" format. I've seen the tooltop t5 and t7 cameras (that must have the same sensor), but for have the macro, i've had to buy 2 cameras (t5 macro and t7 normal fixed focus), they not have the lens option.

Even trying to access it with ffmpeg results in errors. Trying the latest python raw dump example results in an error message saying this is not a capture device.Anyone know if Topdon pulled the plug on this open source project and implemented something in the camera firmware to block access to the device?Edit:Seems I was in error. My laptop lists /dev/video0 (my webcam) when nothing is connected when issuing 'v4l2-ctl --list-devices'.Connecting the TC001 then shows /dev/video1 and /dev/media0. I assumed since /dev/video0 was already present, that my TC001 would be /dev/video1. I was wrong.Using /dev/video0 along with @aurel commands fromhttps://www.eevblog.com/forum/thermal-imaging/infiray-and-their-p2-pro-discussion/msg4665403/#msg4665403I was able to get mine working.Now that I know it works, I can have some fun.Thanks to everyone in this forums.

content: Infiray have apparently continued their development of their thermal imaging cores. We have already seen ‘V2” versions of their camera dongles and there is now the release of the Tiny2 imaging core. The Infiray P2 and P2 pro use the Tiny1 imaging core and I have not seen references to a P2 V2 or P2 Pro V2 so it appeared that the P2 series were not updated when other dongle cameras were. The V2 versions of other dongle cameras were incompatible with 3rd party software that had been created for the V1 cameras so the authors had to make some changes for V2 compatibility.Now to Thermal Master and their P2 series……I can make no comment on whether Thermal Master are part of the IRAY/Infiray spiders web of companies but I can advise that a representative of Thermal Master insists that they are an independent company and not rebranded Infiray. I have yet to research Thermal Master and their obvious links to IRAY/Infiray but that is for another day. I was surprised to see a new dongle camera called the P2 coming from Thermal Master and they have even sent one to me for testing. The P2 Pro is also available from them but that looks like a rebranded Infiray product. That said, it may either use the new Tiny2 core or a Tiny1 core with changes to the USB identity that confused software created for the Infiray P2 series. I can state that my Thermal Master P2 unit has a completely different USB ID to my Infiray P2 Pro. There is also the possibility that the Tiny2 core is the new “V2” technology that we have already seen used in other Infiray dongle cameras.Infiray, as a company, appear to be in a period of reorganisation/restructuring and it is challenging to work out exactly what is happening with regard to changes in their product offerings. I suspect that they are providing hardware and software to companies like Thermal Master, but they may be using revised core versions and/or modified USB identities to distance the product from Infiray and IRAY.Fraser

content: Hello everyone! This is my first ever post on this thread, and even on this forum. I'm an undergrad CS major and am currently doing a personal project involving these sensors (this is one of my first ever "major" open source contributions, so constructive criticism is welcome).I currently have a TS001 and attempted to use the "PyThermalCam" script written by Les Wright (original forum post:https://www.eevblog.com/forum/thermal-imaging/infiray-and-their-p2-pro-discussion/msg4949002/#msg4949002) to just test the system. Unfortunately, it did not quite work immediately with my system (Windows 11, Python 3.12.4). I figured out the solution(s) through tweaking the code and removing certain drivers, but while doing so thought I just might as well continue where Les left off and hopefully help others in the process.I have forked, refactored, and overall cleaned up the program. It is now much more readable, largely follows OOP principles, and is pretty modular. It practically constitutes as a rewrite. I am still in the process of refactoring, and there are absolutely still issues (specifically with the sensor temperature calculation), but the overall functionality of the program works and I was able to test out my TS001.This fork is specifically designed to work for theTS001onWindowswith newer versions of Python and OpenCV; however, ithypotheticallyshould work with TC001 and Linux too. I will be actively updating this repo with changes, fixes, and additions over the next few days/weeks.Anyways, I hope it helps someone struggling like I was for a while.

A technical limitation by Apple, or does InfiRay consider this product an old model and just isn't putting resources towards it anymore...?It looks like the USB-C HIKMICRO Mini2Plus V2 has found a way to be dual iOS/Android compatible, so it is possible. But it's not available in the US, so for me it's not an option.

content: Hi all,I've had my Thermal master P2 Pro a week now and I've noticed that on the side of the image there is a dot showing in the images. When I switch the auto hottest/coldest point measurement on, on occasion this dot gets measured as the temperature. Is this a fault with the device?The dot can be seen clearly on the right hand side of the images

content: Any pixel, or group of pixels, that are not brought to the same level as the rest of the image during a flat field correction event are out of specification. That said, some small difference in pixels can occur during use through individual pixel temperature drift characteristics. If the pixel causes the hot or cold spot tracking function to misbehave, that is a fault IMHO.I suggest you contact the supplier and request an exchange.Fraser

content: Thanks for the response Fraser, I suspected this may be the case but I just wanted to be sure. The camera was bought directly from Thermal Master on Aliexpress - I was told by their customer support that it looked like a spec of dust on the sensor, but I'm not convinced. They offered me a partial refund, which I accepted, but now I'm realising this was a mistake and I should have just initiated a return. For some reason them issuing me a partial refund has now disabled the return option. I guess this was their motive so they could avoid accepting the return. My own fault for falling for this.My only hope now is that they honour a warranty replacement but given track records of these companies for warranty replacements, I won't hold my breath.

Unfortunately due to apples DRM(?) chip etc... finding a replacement port is not easy.I decided to solder a usb-c cable to the correct pins on the pcb and managed to get it showing in windows (see pic) however it does not show up as a uvc device, ive tried installing all kinds of drivers Infiray official, TopDon, generic libusbK drivers but still cannot get it to detect in any program (or show up as a uvc device).If I install the official Infiray PC software/drivers during installation it detects "com.xinfrared.pios1" and installs "infiray falcon001 5840" but the actual windows program does not detect the camera (and the Infiray Falcon001 5840 driver doesn't seem to have uvc capability)Anyone have any ideas on what I could try next, maybe try to solder to the camera module directly using the unlabeled test points?

content: Hi. Any clue why these upscaled images from p2 pro are not correctly read by SharpInfraredAnalyzer (when upgraded it turns to Temp Master from ThermalMaster) ? When the image is shot with laptop it gets 256x190 and is editable in pc software but if I download stuff from phone directly it simply fails or gives black data.ps: just a small edit - i've installed te temp master for android and the images taken by it are processable by PC. The drawback is i've lost 25fps (as in p2 pro app) and it feels like 10-15fps. Omg.ps2: i've turned off 'X3' option and it gets 25fps...I assume I solved myself.

I also queried Thermal Master about this and they said they would mark the replacement as a 'sample' as to not attract any further VAT/duty. Not sure I'm happy about this as it breaks the outward processing rule and delegitimises the warranty process. If it did get caught up in customs, this may not end well. That's also assuming the thermal camera gets to its destination and if so, the company can really can do what they want, there's zero consumer protection and therefore the camera could go in to the ether and I lose everything.To be honest given the risks associated with returning an item back to China with zero accountability, I think I'll just keep the camera and live with the problem. There are too many red flags with this and I wouldn't trust the warranty process that they claim on their website.Motto of the story, try and order locally and pay more for peace of mind (if possible) or just hope that if you order one of these devices from AliExpress or directly from their website in China, that everything goes smoothly, because if it doesn't then you're pretty much on your own. :-(

content: I have been using an InfiRay P2 Pro with its macro lens as a part of an infra-red telescope to take pictures of the Moon.The telescope is based on a modified Celestron FirstScope (75mm f4 spherical main mirror), The secondary mirror has been removed to eliminate infra-red radiation from it spoiling the image. As it is no longer used, the eyepiece focus tube has also been removed, The main mirror is tilted by a few degrees so that the focal point is just below the lower edge of the telescope tube (see attached ray diagram), and the P2 Pro is placed near to the focus. The telescope in this configuration was first used in the mid 1700s by William Herschel, the discoverer of the planet Uranus. A photo of the modified telescope with its red dot reflex sight is also attached.The telescope has been used to obtain false colour infra-red images of the Moon from when it is a few days old (crescent) up to a full Moon. A few images are attached.I have also been developing another telescope using the P2 Pro and a 50mm f5 ZnSe lens. This has a resolution similar to that of the FirstScope Herschelian configuration.

I do not use the YUYV stream at all.I have yet to implement "Save Video", but other functions are fully working.That is, cycling colourmaps, subtracting background and saving thermal images to tiff files in full bit depth (viewable in ImageJ).Tested in Linux and works with full device path to camera "--device /dev/video#".GUI is editable in QtDesigner.On Windows, I think path will need changing to an integer.If people are interested, I will continue development.Screenshots and code attached.Thanks,Shailen.

content: Quote from: LeoDJ on January 28, 2023, 07:16:33 pmDear all,I’ve just joined the forum, and I apologize in advance if this post is not in the right place.I recently purchased a Thermal Master P2 camera, and I'm working on extracting temperature data from the raw image files for further analysis. So far, I’ve managed to retrieve the raw data from the JPG files and convert it to temperature using the formula suggested by LeoDJ (Thank you for that helpful insight!):Code:T = x / 64 - 273.15 (Eq. 1)However, I’ve run into an issue when switching the camera to extended range mode (100–600°C). The conversion using Eq. 1 appears to give incorrect results, even though the Temp Master app and the saved JPG image show accurate temperatures.I tested a hot source at approximately 280°C, verified with both the Thermal Master P2 and a FLIR E75 camera. Both cameras reported a consistent temperature of ~280°C, so I’m confident that’s the correct value. However, when I extract the raw values from the JPG and apply Eq. 1, I get a result of 310°C. In another test, a source at 310.1°C yields a converted temperature of 442.7°C using the same equation, a clear mismatch.I also tried reading the image using P2 Pro Viewer (https://p2proviewer.streamlit.app/) and observed the same (incorrect) temperature values, which suggest the issue lies in the conversion rather than the raw extraction.Has anyone else encountered this issue?Could there be a different conversion formula for the extended temperature range?Does the raw data scale differently depending on the camera's gain mode?Is it possible the camera applies a different calibration internally that’s not reflected in Eq. 1?I’ve attached some sample images (next comment) in case anyone wants to investigate further or run their own tests.Any suggestions, insights, or guidance would be greatly appreciated! Thanks in advance for your help.Best regards,Simone

From what I can tell, it seems that the in-app displayed temperatures are calibrated on the fly, while the exported JPGs don’t include those corrections, so they end up saving uncalibrated data.

content: While I appreciate your point about angular effects potentially influencing temperature accuracy, I believe their impact in this setup is minimal. If the discrepancies between the app-displayed temperatures and those derived from the raw data were primarily due to acquisition geometry, I would expect a consistent trend, either increasing or decreasing with angle or distance. Instead, the deviations appear non-linear and do not follow any predictable pattern.Furthermore, based on the available documentation and my understanding of the Thermal Master (Infiray) modules, the internal correction mechanisms account for emissivity and distance (to handle attenuation and atmospheric effects), but not for the angle of observation. This supports the idea that the angular offset alone is unlikely to be responsible for the inconsistencies observed.To strengthen this analysis, I also conducted controlled tests using a temperature-regulated heating plate. The camera was mounted on a tripod at approximately 2 meters from the target to ensure stable acquisition conditions. The residuals plot (see attached) shows a deviation pattern that is better explained by calibration drift or software-side correction inconsistencies rather than geometric distortions.

content: Among the 6 factors that influences the emissivity, are shape, angle and surface.When the angle of measurement is greater tan 45° then emissivity is no longer static.The impact of the angle is huge!In this case, the angle is way more than 45° and the change of emissivity is not lineair, hence the huge error in measuring.Use of thermography with an angle of more than 45° is not only a bad practice, it shows one does not know the huge impact onto the emissivity and therefore the measurement is truly unacceptable.Distance by the way, is never an issue in reality because atmospheric conditions do not change unless the measurement takes place at at distance of several hundreds of meters.While I do agree that in this setup the differences are probably due to drift or wrong corrections internally, this measurement is by default not acceptable solely because of the bad angle.So why bother about the other issues?

content: @Sorama Thanks for the interesting observations and thoughtful points, vey much appreciated!You're absolutely right that the angle of measurement can have a significant influence at extreme geometries. While I currently believe that, in this particular setup, the impact of emissivity due to viewing angle might still be minor compared to other sources of error (such as calibration drift), I’m completely open to verifying whether that assumption holds.That said, it's important to note that my testing isn’t intended to assess the accuracy of true kinetic temperature readings. Rather, the goal is to understand why discrepancies arise between the thermal data shown in the app and the raw data retrieved from the system.I'll be away for a few weeks, but I do plan to revisit and replicate the experiment once I’m back. It should give a better indication of whether the viewing angle contributes significantly to the observed offsets. I’ll keep you posted on any developments.As for your question regarding the surface and dimensions: I’m not currently in the lab, so I can’t provide precise details at the moment. Roughly, though, it’s a 20 cm rounded heated plate with a dark-colored heating base. I’ll share more specifics once I’m able to rerun the test.

The original lens was very thin (less than 1 mm thick), about 12 mm in diameter, and had a slight golden or mirror-like appearance. When I removed it, the camera worked fine, but when I replaced it with a regular glass lens, the camera couldn’t see anything.Could anyone please confirm what material the original protective lens is made of? Is it Zinc Selenide (ZnSe), Germanium (Ge), or something else?

content: The lens protection window is made from Chalcogenide IR transmissive glass, as is the cameras actual lens. Sometimes Silicon is used but that has poorer transmission characteristics at LWIR wavelengths so must be kept very thin.Ordinary glass is opaque to the LWIR spectrum, as you have discovered. The cameras measurement system will have been calibrated to take account of the small transmission loss introduced by the thin window but the error introduced by the absence of the window will be very small. The Thermal Master P2 does not have the window and you can operate your P2 Pro without it if you want. If you desire the protection afforded by the window on the P2 Pro, you will need to find a ZnSe, Germanium or Chalcogenide IR glass (GASIR) window of the same diameter, similar thickness to the original, and it must be AR coated for LWIR use. Infiray and Thermal Master do not offer the window as a spare part that you can purchase. A thick window will introduce slightly more transmission loss and may interfere with the correct fitting of the close-up lens.Hope this helpsFraser

Whilst I could find a “Polished”, uncoated window of the correct dimensions, I could not find an AR coated window. Do not be tempted to use a window that is not AR coated for LWIR, it will perform poorly and ruin your cameras measurement accuracy.In your position, I would likely use the camera without the window, as with the TM P2. A custom made LWIR window will likely be uneconomic. Warning, if you find a ZnSe window with the idea of cutting it down to the correct diameter, do not do so. ZnSe is harmful if cut or ground.Fraser
