content: Hi,Because i couldnt find any infos or reviews about this unit i just bought this device. I was looking for a reasonable priced but good quality thermal camera for smartphones with a not to bad resolution. I am a bit disappointed of the device i have to say but since its my first thermal camera maybe i expected to much despite reading and watching hundreds of youtube videos of similar cameras before. The first thing i dont like is it produces sometimes ghost images when i tilt the camera arround, i made a little video of it, maybe someone with the same camera can confirm if that is normal or not ? Also annoying is that the temperature data is not recording in the video, i see it on the smartphone but in the video file the Min. Max. temperature is missing, only in the pictures you can see the temperatureAnother thing is that the autofocus is missing the correct distance alot, you can adjust it manually with the volume +- button. The autofocus you need to tab the screen, otherwise it wont adjust by itself. The App can not be downloaded from the playstore, only directly from Guide in Wuhan. Thats why i actually bought a cheap Xiaomi redmi note 11 just because of the thermal camera and for this purpose because i dont want any questionable apps on my main phone. Now i was thinking in sending it back for a device with a little better resoluition like the HTI HT-301 or Infiray T3s but i dont know if the difference is that much better. For my taste the videos of the guide are just a bit to pixelated, maybe i expected to much.

content: The smearing looks to me to be down to the amount of frame averaging / image processing being done to reduce noise.It also seems to have limited greyscale levels, resulting in flat blotchy areas, which might just be the video compression for YouTube.

content: Quote from: Bill W on December 11, 2022, 12:25:32 pmThe flat blotchy areas are also in the original file, it looks identical to the youtube file. Thats what i thought, i saw alot of reviews from seek, Flir and chinese models and many of those produced alot of noise, like grain in the image but with more details. The one i have dont has noise but dark areas look flat and blotchy. I watched for a example footage of a camera with slightly more resolution, the HT-301 and the video of someones hand looked also better, you can see hairs and stuff more cleary but in dark areas you could see the cold objects much clearer. Maybe because the sensor size appears to be larger on the HT-301 ? I mean it has a much larger lens that sticks out of the cam while the MobIR 2s has a much smaller lens. I bought a relatively weak smartphone with the xiaomi redmi note 11, can this also be a factor ?

content: The smartphone has nothing to do with it. An older Samsung Galaxy S5 would also suffice if the Android version fits.The difference to the HT-301 is firstly the higher resolution (384x288) compared to your camera now (256x192). Second: the HT-301 has a manual focus hence the protruding lens. I don't know how the autofocus works on the Guide MobIR 2S. The disadvantage of the HTI-301 is the annoying calibration mode which freezes the image every 10 seconds. I don't know if they had since fixed that or changed it. There have also been reports of some people having to remove the dongle and then plug it back in again because the software crashed.So for the 440 EUR or what you paid I think the picture is very bad compared to other manufacturers. This is probably primarily due to the software which apparently still needs to be improved.Your image looks normal for a resolution of 256x192 except for the strong blurring to reduce the noise. The manufacturer HIKMICRO used to do it that way too until reviewers then called for improvements. They were then able to correct it in the meantime.As for manufacturers of thermal cameras I would personally only use INFIRAY or HIKMICRO nowadays. How important is a smartphone dongle to you? Because HIKMICRO also has thermal cameras of very good build quality. E.g. the Pocket 2. If you are more interested into a super sharp image, maybe for "thermal photography", then Infiray is currently ahead with its T3S because they offer a very good sharpness of the thermal image and here also offer a higher resolution (384x288). Of course it's about double the price.I had various devices with 256x192 resolution: These are recommended as the minimum resolution for general rough tasks, e.g. checking electrical cables, electronics (with macro lens) or heating systems. For a more detailed investigation (or, as it looks like in your case, more the visual impression of the surroundings?) a higher resolution is recommended.To be honest I personally wouldn't bother with third-class manufacturers like Guide. Likewise Seek or Flir are also out of the current race, at the moment.

content: I thought guide is considered as a good company because they produce the sensors unlike many other brands. The Autofocus dosnt work that good, it misses the correct distance in some situations and you have to tap on the screen for Autofocus, so i think to manually focus is not that bad. Ok, i think i will order the T3S because of the good price now but i have concerns regardings the App. In other threads people report that Android 10 is not supported for the "Xtherm" App and when you read the App info in playstore it says you have to download a newer version from Xtherm directly from them.That would be no problem but some people say even this newer version is crashing when recording videoThere is also another App called "Xinfrared(Inforayserach)", it also says you have to download the Android 10 version directly from themSo that is really confusing. Am i right that the first app is for meassuring temperature and the 2nd App is primarly for night vision ? Yes i paid 440 Euro and for 150 more i can get the T3S, that would be ok for me.I only have three conditions when i order, no visible dust or dead pixels, recording video is possible and it have to run on android 10 because i bought a xiaomi redmi note 11 for that purpose at the black friday sales and it would be annyoing when i have to sell it.To the freezing, that calibration mode is also present on the Guide but very mild and the click is super silent and i think its not every 10 seconds but as i said i am a bit disappointed from that device. Should have bought a higher resolution one but the videos from the T2 pro looked pretty good to me, thats why i thought the lower resolution was enough.As an alternative App people always write about the Therm viewer App but its not in the Playstore, do you know where i can officially download or buy that app?

content: Hikmicro and Infiray also produces their own sensors. But they are on their way to fix software issues. Guide seems to be not so good at that front.I'm not really a fan of these dongle devices for smartphones. I also wanted to try the HTI-301 or the T3S but decided against. Firstly because the HTI-301 is specified as having a NetD <60mk (which would be much worse than my Hikmicro device) and accuracy of only 3%. I also would have to buy an additional phone. All this for optically more beautifulsharpenedphotos... for me the temperature measurement is the decisive factor, not how beautiful the pictures look. But I can fully understand your desire. Please consider that if you don't have a clearly defined application for a thermal camera then it'll be a pretty short gimmick. At some point you tried everything to point it on.Then there are also these app problems: People are always dissatisfied with the Infiray/HTI app. That's why I don't like the dongles. There is the risk that at some point the app will no ​​longer be supported by your cell phone or the manufacturer does not develop it further. A standalone device will continue to work even in 10-15 years but the drawdown is the battery which has to be replaceable. Someone is always complaining about the apps but I haven't heard anything bad about the standalone devices.I am also convinced that there is still a lot to come in the future in terms of optical and thermal resolution. Maybe just try something now so that you know what you need/want and what doesn't work for you and then wait a bit? I think the whole sector will look completely different in 3-5 years from what is offered to us now. I would really hate to play the beta tester for immature apps.There are tremendous improvements underway, almost a revolution, in the field of outdoor thermography. If you compare the quality of their devices with that of our temperature measuring range here you think you are in a parallel world although basically its the same technology. They are currently at 640x480 / <20mk with high-quality (larger) full germanium lenses including telefocus (2x) for <3,000 €. If this continues I'm sure the same technology will also be used in our temp measuring range in the upcoming years. Maybe then they have resolved their app issues. It will also then be much clearer who the leading manufacturers will be in this newly restructured area.

content: Yes, i saw that <60mK but i thought to myself who knows if the competitors stated the correct numbers because i guess there is alot of lying going on there as well in the specs of those devices and generally with other electronical devices or even 18650 batteries. My guide model has 2% and <50mK, detector type VOx, 7mm lens, 25° FOV but is that honest? nobody knows. So the sensor should be more sensitive on my model, right?Stand alone devices are nice but i dont like the non replaceable battery and i dont like to take care of the battery every 6 months, thats why i prefer a smartphone version. The smartphone dongle has several benefits, you can record video which the guide PC210 or the Uni-T stand alone model couldnt do, thats why i went for the smartphone version. The problem with the App and updates is not a problem for me because i bought a cheap Xiaomi smartphone only for using it with the dongle, i will never update the smartphone or the app when it works. So it will work in 8 years as well, i dont even need internet working or other apps. Its bascically only a giant "screen" for me. I use an iphone 13 pro max as my main smartphone, thats why i wasnt afraid of viruses or backdoor programs. I agree that the stand alone device look nicer and give a better feeling but what device offers such a large OLED screen my xiaomi smartphone has? Also working with the app is very fast because of the touch screen etc.. Another benefit, the dongle is smaller and more mobile and has no battery. They are usually also cheaper compared to stand alone devices.

content: Quote from: Danielsan79 on December 11, 2022, 07:19:51 pmOkay, if you don't change the smartphone and only use the same app and device it's probably the same.But can you change the battery of the smartphone in eight years? Same problem with standalone devices. If you don't use the Xiaomi for other reasons then you will also have the need to take care of the device every 6 month (recharge the battery).Quote from: Danielsan79 on December 11, 2022, 07:19:51 pmI'm wondering how the manufacturers manage to upscale a small 384x288 pixel image onto an OLED screen with more than HD resolution without making you nauseous?BTW, Hikmicro's Pocket 2 also has a touchscreen (640x480 pixels).Seems you've got what it takes (Redmi), now find a good store and try an HTI-301 or T3S, preferably a trustworthy store where you can return the items if you don't like them. Incidentally I don't find that so easy with HTI or Infiray: there seems to be only Amazon and both only ship directly there, not via Amazon.Maybe you like it? Everyone has other priorities when using a thermal camera. Try it out.

content: True but a cheap smartphone with Android 10 will be available in 10 years, somewhere on ebay for sure. However nobody knows if a spare battery for the thermal camera is still available in 8 years from now, especially with a chinese brand. So if i am lucky my thermal cam will be still working in 8 years but need a battery and then i have a problem and even if spare batteries are still availbale, they want money for it and the installation. Thats why i dont think the HKmicro pocket 2 is a good idea, its expensive with over 600 Euro and has the same resolution as the guide. For the same price i got the android phone and the dongle, which is not bad to have two devices and more versatile. Of course i use the redmi 11 for google search or something like that, youtube etc.. i just wont put in personal data, banking APPs and all that. Yes the OLED screen is large and the original resolution is much smaller but the App dont use the full screen for the Video feed but i can imagine that the screen on a todays smartphone is much nicer than the ones they use in the stand alone devices, like viewing angle, OLED, colors. Another point is if you have a dongle there is less that can fail in my mind. Because if you screen fails on such a stand alone device you have to send it in and who knows if it can be repaired and to which costs. When the redmi screen, CPU, GPU or whatever part fails i can buy just a new one, they are cheap and i think more robust and repair shops can repair it as well. Thats why i thought it is not bad for having two seperate devices, you also have a free camera in the smartphoneI saw one on idealo for that price, will check that again, i think it was 590. For 900? i will keep my guideor buy a T2s instead. I also thought about the uni-T UTi730E but i think the T3S is the much better solution.Edit: the only negative thing about the T3S is the pixelpitch is 17 while the guide has 12 which is according to google a more modern design. a lower number means sharper and more contrast in the end.

content: Quote from: Danielsan79 on December 11, 2022, 09:36:35 pmThat is not correct.12um is 'newer' but a smaller pixels inevitably mean worse signal (simply due to pixel area) to noise.Maybe the vacuum is better, or internal electronics improved, or they just had to throw more software noise reduction at it.12um also pushes the lens design harder, so must be worse optically, until they throw more sharpening at it.If they increase lens aperture to fix the noise, the sharpness falls off. Cannot win !However 12um means more chips per wafer, so is cheaper / higher profits.

content: Thank you, that is good to know. A thermal camera shop had exactly the opposite text on their website. I think i will buy the T3S then but my concerns are the poor App. The Xtherm App is extremely basic, actually the guide App is much better in that regard, you can adjust brightness, contrast, set temperature range, it even has a dedicated night vision mode. What i really like about the T3S is the clearer image but i saw in many videos that for example humans or animals in a city at night are hard to detect because they dont glow as much as within the guide app for example. The guide shows houses and other objects only blurred and with darker color, humans and animals very bright, so you can detect it much easier. In the Xtherm app you can see everything pretty good and that makes it hard to detect animals. A temperature range option or contrast option would probably help, to set minimum temperature at lets say 30°C. Then there is the problem with Android 10, many people wrote that the Xtherm App can not be used under Android 10, even the updated version directly from Infiray will go black when you hit the record button. I want a thermal camera for multiple use cases, like for household use but also fun use at the forest for example. So the FOV should be not to wide and not to narrow.The aftermarket App ThermViewer is a myth, nobody knows where you can buy it, its a bit dubious.

content: Quote from: Danielsan79 on December 11, 2022, 09:36:35 pmThis is definitely worth considering and makes a lot of sense. But I would have to try it myself first to evaluate the advantages and disadvantages. You often only notice the difference when you use it. But thanks for the suggestions!Sounded like you wanted to put up a fight with my arguments but I really had no intention of dissuading you from the idea of ​​using a dongle with a smartphone.Quote from: Bill W on December 12, 2022, 11:38:45 amWe used to have the same discussion about whether more megapixels would be better in optical cameras because you can't handle that much resolution and the SNR degrades. It was agreed that 6 megapixels was the limit between good resolution and pixel size.But that's no longer the case nowadays either as technology has progressed so far that the image quality with smaller sensors is umpteen times better, due to various improvements, than a large sensor with 6 megapixels. This will certainly also be the case with the thermal cameras.But basically what you say is true, of course, especially at the moment in these "times of upheaval".The question always arises as to what is more important: I can see objects in the distance better with a 17 µm pixel pitch sensor than with a 12 µm pixel pitch sensor. If I need exact temperatures then I use a 17 µm PP sensor because of the better SNR ratio. If I want nice pictures then 12 µm is enough. If I buy price-consciously then also.In the end we can say that the entire industry can only push ahead with further developments because production costs are falling (ie by reducing the PP) and profits are rising. But then you can also invest more in R&D. Profit does not always mean that in the end there is someone who stuffs his pockets to buy nonsensical vehicles, boats or islands for himself.

content: I like stand alone devices as well, i know what you mean. A dedicated stand alone device feels more solid and its a proper thermal camera, if money plays no role i would propaby go for such a stand alone device and VGA resolution if it could record video. By the way i ordered a T3S, there is a online shop in germany called Liemke and they offer it for that price. I think there is a way to get it even cheaper from aliexpress and a guy on youtube who get huge discount on the infraray dongles, its probably even cheaper than 590 as far as i know but i went for an offical german shop and liemke is part of the blaser group or something like that and they are well known for hunting stuff in germany. For 1000 i wouldnt even think of buying it, now i have to add another 150 for the T3S but i think thats ok. I already downloaded an alternative app for it, a private project from a discord member. I think its originally for the T2s+ but it should work with the T3S as well. The quality is not as good as the xtherm app in terms of sharpness but it has alot of functions unlike Xtherm. I will definately test it when i receive the T3S and see if it runs on Android 10 and T3S. My Guide dongle is already on its way back.The only concerns i have now is Dust on the sensor because i saw T3S out of the box with a huge amount of dust on the sensor, there is a youtube video showing it. The other concern is Xtherm and Android 10 because accoriding to some people here it will result in black screen, especially then the record button is tapped. In the worst case i still can activate screen recordI have a feeling that this thermal camera will be replaced in some years because i will buy one with higher resolution.

content: I noticed that an hour ago. Before it said "Black Week" until 15th december and i assumed the price of 590 Euro was valid until that date. I ordered 7 hours ago via the online shop from them, it seems i either got the last one or i will get an email from them tomorrow telling me that it was a mistake and they are out of stock.Maybe somebody from here ordered one after i posted it here, who knows. I hope i dont get an already opened one if i get the last. By the way, do you know how sensitive the lenses from those thermal cameras are? Of course, i will let you know if this device is much better than the Guide model. I decided to send it back because i think its not fair to keep it for 30 days and make thousands of tests with it, i dont like that behaviour. I had it for two days and it was enough to see that i expect a bit more in terms of image quality, the App was actually not bad at all. Since i alreasy installed the Xtherm i can see that its much simpler.

Or how sensitive they are to scratching?Found an interesting report about the T3S:https://s3.i-micronews.com/uploads/2020/11/iRay-T3S-performance-analysis-report_Sample.pdf

content: Sensitive in terms of scratching the lensI am not an eletrician and have no experience in thermal cameras but i can imagine that those lenses are specially coated. I will avoid to touch it but would be good to know how it can be cleaned without damaging it.That is a very large and accurate test of the T3S, like i said its hard to understand for a non expert but it seems the T3S is not that bad. I dont think the manual focus is that bad, i had the Guide device with Autofocus and yes it is more comfortable to tap the screen for focus, if the focus is correct and that was sometimes not the case, so i had to manually focus it. Unfortunatley the status of my T3S ordering hasnt changed yet, i hope they will send it to me because as you wrote yesterday, it is now ouf of stock or better said there is a text saying its only available at their stores i guess. If i dont get it i will order a T2 pro i guess, pergear has them for 339 Euro? The only thing i dont like here is the lens, its a bit to much of a tele lens for my taste because its not really nice for closer objects inside the house. The Guide had 7mm and the FOV was already a bit narrow, the T3S has 13mm i think and has a slighty more narrow FOV, the T2 pro is super narrow.I can imagine that the accuracy of the T3S is not that good because it says 3° C accuracy while many other models claim 2°C but who knows if the other brands are honest, i will surely test it against an IR Thermometer i have which should be pretty accurate. It has also a Type K contact sensor and both ways gave me nearly identical results when i meassured a hand warmer some weeks ago. I dont even had to put black tape on it because matte black anodized Alu should be ok with 0.95 emissivity.

content: You can buy the full report for only 6999€:https://piseo.fr/en/press-news/iray-t3s-thermal-camera-performance-analysis/From what I've read here the lenses should be VERY scratch prone but depends on the material: Germanium not so much but the cheaper Chalcogenide is very prone to it. The coatings in particular can also be damaged. Therefore it is recommended not to attempt cleaning. Better just use a dust blower for cleaning. Or alternatively a VERY soft brush.Dust and fingerprints should hardly make any thermal differences unlike with optical systems.

content: Ok, i had to google it but i can not really imagine that the lens in the T3S is germanium because on ebay people want like 700 Euro for a lens, costs more than the whole T3S camera. Maybe the chinese can offer it much cheaper but i wouldnt be to sure, even when they say its made of that materialBut interesting to know that fingerprints dont matter, so its better to leave fingerprints on instead of trying to wipe them away i guess?

content: 'Germanium Alloy' is chalcogenide.It will be moulded chalcogenide to keep to one element with aspheric surfaces. The need for multi-element to do a spherical surface pure Ge would certainly be more expensive.A decent coating should be fine for home use, getting DLC (hard carbon) on chalcogenide has been tricky though.I'd expect a 13mm f/1 single element to be around USD100 at factory volumes.

content: Stupid question, i received the T3S some minutes ago and it looks nice but you get it in two pieces, lens and body, both have caps on it for dust protection BUT i can not see the sensor when i remove the dust cap on the body. I mean when i look at the pictures of the T3S without lens you can see a giant glossy sensor in the back. Is it possible that there is a matte black cover in front of it and you have to remove it? I dont want to hurt that little thingBy the way, the case is a fail in my mind, you have to remove the lens everytime otherwise it wont close, so you have dust entering it all the time. I will not do that and put it in an other case and let the lens always fitted to the body.Edit: Ok, it is the shutter sliding over the sensor. I was irritaded because all the pictures you can find from T3s showing the bare sensor when the lens is removed. I guess they removed the lens when the camera is powered on then?

content: Thermal cameras that have removeable lenses often use the FFC flag to protect the microbolometer windows from harm and duct. The T3S sounds like it is such a camera. It is a good idea but I personally would not want to remove the lens every time I put the camera in its custom made case. As you say, a failI searched out a little hard case for my Infiray P2 Pro and Mike found the same one. He modified the foam insert to fit the new case shape. You may wish to start looking at camera cases and camera memory card cases. They come in many different shaped and sizes so hopefully one will meet your needs and protect t the camera at the same time.Fraser

content: I had to check again and now the bare sensor is visible when i remove the lens, strange. Maybe the shutter is only closed when it comes from factory? I looked a 2nd time because i was scared i might had screwed the lens to deep and hurt the shutter but that seemed not the case. In general i like it much more compared to the guide, the focus is not that much of a problem, for my taste the lens can be screwed to easily, i like more resistance. Also the sound when focusing is not nice, you hear some grind noises all the timeI had to remove the smartphone case because the USB-C connector seems to be small, the guide device fitted with the case but its not a problem since its a cheap smartphone. Temperature wise it is not bad, i had to adjust the correction to 0.0, the app had it on +1.5 which was to much according to my flir IR Thermometer. Of course i switched both devices to 0.95 emissity. The images are more clearer compared to the guide, also it works on the normal version in playstore on my andropid 10 device. Videos are saved in the normal google pictures folder which is nice, the guide saved videos and images in its own app only. It also seems the Infiray videos are not only clearer and sharper, they are alre more fluent.I have an alternative App from someone who made it on its own, this has alot more adjustments but it shows alot more noise.Why is it that the colors of certain objects in the thermal image all of a sudden when you slighty tilt the camera? Is that because of automatic temperature range adjustment? FOr example the desk is blue and when i slightly tilt the camera, the desk gets reddish. I guess it is because you can not "lock" the temperature range?

If you pan the camera these values ​​change because there are other min and max values ​​in the scene but the desk always has the same temperature.Can't you set manual Level & Span on the T3S?

content: Nope, not with the original Xtherm App, its very basic. I have also an alternative app a user made himself. Would love to get my hands on ThermViewer as well but the user responsible for that app is not responding, i guess he isnt even into therman cameras.Since i only made very little videos and images with the Guide MobIR 2S i tried to copy the same scenes with the Infiray T3S and compare them in a little video clip. All in all i am satisfied with the decision of switching to the T3S with the added 150 Euro. The videos looking much clearer to me, its like night and day despite the resolution isnt that much higher. I even thought i made operational errors with the guide because the quality is so different, maybe i didnt removed a protection foil on the lens or something like that but i dont think so, i guess the quality of those 256x 192 sensors is just like that. Its actually more than double the amount of pixels, 50.000 to 110.000. The Guide App however was better compared to the infiray and of course it is not fair to compare the two models because of the different resolutions. The T2S would be better suited here.

content: Quote from: Danielsan79 on December 17, 2022, 08:21:36 pmThanks for the insight. Don't worry, a foil or something similar would not have given a picture at all or would have had no effect - we are talking about heat radiation.Maybe the focus wasn't set right? Looks a little like it to me. Plus the fact that the post-processing of the thermal data is probably not as good/clear as with Infiray.The photos at the beginning with the heating seem to me as if the dynamic range was set too extreme by the automatic of the guide: cold areas are totally black and the hot radiator is totally white. This can then not be corrected without manual adjustment.

content: The focus was always set correctly, i even tried to manually set it right with the volume keys +-. I also discovered that when i tap the area on the screen to focus it started to search a bit for the correct focus, found the correct spot and then decides for the wrong in the end. Yes, i think the post processing is a bit below inforay when i look at similar models with the same resolution. To compare it with the T3s wouldnt be fair of course. Maybe that is why i couldnt find reviews of the product all over the internet. Yes, the automatic of the temperature range is working and adjusting constantly, similar to the T3S. I also used the framing option and added a frame arround the heater. The guide app has the ability of customizing the temperature range and then you dont have the fast changing colors anymore when you tilt the camera.

content: In the Specs of the T3S it says "germanium single crystal alloy lens", does that mean its a germanium lens and not chalcogenide? Im not an expert but germanium single crystal sounds like its 100% germanium, i dont why they say germanium single crystal alloy lens, maybe because the frame of the lens is alloy?

content: QuoteI bought this outdoor case now, couldnt find a smaller case but i like it and i think it was 17 Euro which is ok. It has the pre cut foam, so you can customize it to the correct shape.I should have mailed Infiray because they deliver the T3 search with a nice little case, like a semi rigid hardcase with zipper which has exactly the right size.
