content: If it is the same as my other Scout units you just need to unscrew the plastic securing ring that sits around the lens barrel and this releases the complete silicone coated plastic front piece. The core is then accessible and may be released by removing the securing screws on either side of it. DO NOT just pull it out ! Gently pull it forward to see whether the core will release from its rear connector. In some cases the whole ribbon cable moves forward with the camera core. You need to be able to look at the ribbon as it attaches to the connector on the control PCB. If it is not properly inserted into that connector, that is your problem.Fraser

content: I recently scored a cheap (~$150) thermal camera on AliExpress, and it turned out to be not that bad. The model is HABOTEST HT-820, and it can be used with the apps TOPDON provides on Android and Windows. With 256x192 resolution, it seems to be almost compatible with TC001. I can also access it on Linux, but still struggling to get meaningful image on that.Anyway, I've done a review on github, so check it out if you're interested in buying a budget model!https://github.com/tai/thermal-camera-notes/blob/main/ht820-review.ipynb[ Specified attachment is not available ]

content: Thankfully many of these dongle type cameras are using well known thermal imaging cores that will produce a decent thermal image, provided the host software is not a total mess. The functions offered by various brands of host APP can vary so it is great if a camera works with another brands APP that is more advanced. Sadly some Brands lock their APP to their Dongle to prevent use with other brands of camera.The Infiray Tiny1C is very common in these dongles and you appear to have that core in your unit as it works with the TOPDON TC001 APP. There is now a Tiny2 core so that is a possibility in more recent dongle cameras but I am not up to date on APP cross compatibility.Fraser

content: I just got one too. I don't have other cameras to compare this to so I'm here to ask if this looks fine to you, with a simple flat homogeneous wall in front of the sensor i get this static gradient with a reading 3 degrees higher in the corner, also the calibration click happens every 5 seconds which seems too frequent. Does it maybe need a calibration? or could just be a defective unit

author: LMasterGame
author_rank: Contributor
timestamp: October 08, 2025, 07:18:57 pm
content: The frequent FFC calibration happens specially when the camera is just turned on, since the sensor is cold and in the process of heating up, non-uniformities appear on the image.And the gradient I'm not 100% sure, but it might be happening because local heating, maybe from the FFC shutter coil. And if thats not the case, then it might have bad NUC from factory.
Is it impossible to do athermalized + auto-focus?  - Page 1

timestamp: October 10, 2025, 09:48:29 am
content: Hi, I am in the process of sourcing a thermal PTZ camera for outdoor use, and I am being told by suppliers that it is impossible to have both an athermalized thermal lens and auto-focus in the same camera.They are saying you have to pick between athermalized with fixed focus, or non-athermalized with auto-focus.My understanding was that athermalization is important in outdoor use cases in the case of temperature fluctuations, to keep the camera focused, but that auto-focus is needed in order to look at scenes of varying distances (otherwise you are locked into just a single focus set at time of deployment).Am I just mistaken and it really is in fact not possible to have a camera both be athermalized and have auto focus?

author: IR_Geek
author_rank: Regular Contributor
timestamp: October 10, 2025, 04:17:32 pm
content: Interesting question. You mention PTZ and assuming you truly mean you want to 'Zoom'. By zooming you are changing lens positions or adding/removing lenses from the optical path. In that case, your athermiliztion would be taken care of by auto focus. Athermilization is for fixed optics that compensate by material expansion/contraction to keep focus. Normally that would be focused at infinity but I could see some special industrial cases to be focused at a specific object / distance.A point of concern could be how well the autofocus algorithm works or how well the position calibration is from factory.

Does this need calibration at the dealer?- Does the camera have a 640x480 sensor (like the T560)?- Has this camera model been hacked in any way so far?- What are my options regarding close up shots?

I think it was Fraser who mentioned that it won’t be moving quickly since the Exx and T5xx series cameras are still pretty expensive. I guess it’s a waiting game.I would like to get just a little bit closer than the 42 lens I have allows me, but buying the macro lens (~4000€) and enabling macro mode (~2000€) just seems a bit too much. I bet there are some DIY macro lens options out there. For macro distances, accuracy for me at least is not a big concern.

content: Hello I am looking into purchasing my first thermal imaging camera, as i would be using it in every project moving forward, i would like to hopefully purchase something in the mid - high end territory, with a budget of ~500$. I would be mainly using it for electrical project checking for overheating breakers, relays or other components. I also dabble in PCB making so it would be nice if it can capture small components (with a lense upgrade maybe?)I would like to hear what are the popular favorites.First major question is : Handheld Standalone or a phone attachment thermal camera? which would give me a better thermal image? As i don't mind about the form factor, i would rather get a slightly accurate or higher resolution (dont know if these are specification i should be chasing) than a bulk or slim (whichever is is unwieldy to use ). I both have a USB-C iphone and a USB-C android as my daily drivers, so any phone attachment thermal camera i should be able to useSecond question: It is possible that i will not be able to purchase the models that you recommend, so may i know what specification should i prioritize when choosing a thermal camera? Resolution? Frame rate? lenses ? I just have no idea yet.Thank you so much, your insights will be greatly appreciated

Meanwhile, other devices are now on the market with multi-platform compatibility, e.g. the TC002C Duo (and, yes, TM's P3 - but fool me once, etc.).Can anyone confirm if the TC002C Duo (specifically this Duo model) shows up as a UVC camera when plugged into a PC or Mac (or anything else supporting UVC cams)? I'm hoping there's a chance for third party apps if the manufacturer drops support or is out of business.Any other thoughts on this camera, or a similar alternative (USB-C, wide temp range, adjustable focus, decent software), are appreciated.Thanks!

I'm using mine in a more industrial setting, however I don't require pinpoint accurcacy for the most part (although the more accurate the better). I have been using a Vevor Sc240 that I got from Home Depot awhile ago, and so far it has impressed me enough that I would like to upgrade to whatever would be the logical next step in higher quality devices. Im aware of higher quality name brands like FLIR, however what concerns me is their lack of higher refresh rates when compared to the Chinese devices, in which I much prefer that user experience.Im not super concerned with budget, however I would like to be under $700 if its another "Chinese" brand, however if there is a good new comparable with a name brand behind it I'm ok with exceeding that budget by a bit. I have mainly been looking at the Topdon TC005 as an upgrade over my Vevor Unit.Thanks for your assistance!

I’ve been thinking about getting one myself.USA

For some, a small gadget connected to your smartphone is ideal for its portability and getting close to a pcb in a crowded case, for others a standalone device with a good screen and rugged case is essential.I have several IR imagers: a cheap A-BF RX500 which is probably similar to your Vevor device (i.e. nothing professional but really not bad at all), a tooltop T7 pro (gadget for android, very handy for electronics and on the go with a surprisingly good app) and recently an Thermal master Thor002 (large hefty device that feels professional. Had to return the first instrument but got a free replacement that performs very impressively).We have a forum member who is really into thermal cameras and posts his extensive reviews here on a regular bases: Look for user Fraser.

I know Tau2 has many variants and option codes, and some labels can be cryptic.I’d appreciate help decoding the following:What does the letter “C” or “E” on Tau2 labels actually designate (configuration/class/export/grade)?The printed number on my unit: “41640001X 259322”. I’ve never seen a Tau2 part number starting with “41…”. What does the “41” prefix represent?Is this core 9 Hz or 60 Hz?Is it a “Performance/Professional” grade or an “Industrial”/OEM variant?Any tips to identify the exact FOV/sensor/resolution from label or boot behavior?Thanks!

content: TAU cores that were integrated into systems often have unusual identification numbers on them. They are part of FLIR’s integrated core system so the exact specification is often not detailed in the part number. As has been stated, the basic coding says it is a TAU 2 640 with no lens fitted but the frame rate and performance identifier are not provided as that would be detailed in the original equipments integration document. If you use the GUI in its advanced mode you may be able to determine more about the core. That is if you can get into the full GUI menu areas as some cores restrict what may be done with them via the GUI. It is not uncommon to find TAU cores in CCTV applications that have a different ID coding to standard ‘retail’ cores. Customer configured cores for specialist applications can have very different ID set that are not in the public domain.

I'm sort of a passive member over the years with a wealth of knowledge I picked up in my 28 years as an electrician/engineer tech/electrical inspector/geek that is currently dabbling in electronics. Just two minutes ago I realized there's a section about thermal imaging so this is my first post in here.I'm not by any means a subject matter expert on thermal imaging. I am a Level 1 certified thermal imaging technician where I use at work doing electrical surveys on navel vessels. We use a T530 FLIR camera as well in the past I used a FLIR E4. If you have any questions about the T530 or doing electrical infrared surveys. Give me a shout and I'll give you my 2 cents. If you want to talk about Emissivity, reflective heat in your pictures, and the science behind the scene, I'll leave that to the experts here. 🤣

The FLIR T530 is a nice instrument; curious if you mostly work in spot-check mode or do you record full radiometric images for later analysis?Looking forward to hearing some of your insights on field challenges, like dealing with reflections off painted metal or keeping measurements consistent in windy conditions.

The very first board we did, an 87 foot Protector Class Coast Guard patrol boat and found the attached picture. It turned out that there was some sort of micro bump of some, maybe, slag from when the breaker was manufactured 25+ years ago. The "bump" prevented the contact surfaces from sitting flat with one another so it limited surface contact between the two. Found it, popped it out to where the bump is now a micro dimple and hotspot went away.

There is no way, for example, I'd have been able to afford a fire service thermal camera when they were first introduced, yet now I own several. Others on this forum probably have similar stories.So, clickbait - yes, perhaps, but at least it's firmly on-topic and well-intentioned.

The site filter seems off: picking 25 µm + 640x480 should mean ~20 mm image circle, yet it lists lenses that vignette. I just pull the PDFs and compute the diagonal, or filter by image circle ≥ 20 mm.

I've used it for the past 2.5 years without any problems.I have already done a Reset through the Menu. It's not an emissivity or ref. temp thing. It's set to the low temp range. Battery is OK. It seems to self-cal every now and then, as usual.Any idea what else it could be, or what I could try? Is the calibration data suddenly gone?Version: V1.4.5.20230117Firmware: V1.2.3.20230112Thanks,Ben

content: Loss of calibration tables would create far worse symptoms than you are seeing. The error you have is more subtle.The cameras measurement system uses the FFC flag as a temperature reference to fine tune the measurements. A temperature sensor in close proximity to the FFC flag is used to measure the air temperature around the FFC flag to determine its true temperature as a reference point. It is more likely that the error is in that part of the system than the cameras calibration.This is not a fault that I can diagnose remotely.Fraser

The effect of distance on IR temperature measurement - an interesting paper - Page 1
Forum section: electronics / general

author: Fraser
author_rank: Super Contributor
timestamp: August 11, 2025, 12:28:30 am
content: Whilst doing some other research I came across an interesting paper that discusses the error introduced into IR non contact temperature measurements by the distance to target. It uses a simple IR thermometer as the measuring device but the issues also apply to thermal imaging cameras. An IR thermometer has the disadvantage of a relatively large spot size compared to a thermal camera but in the detailed testing this was not a factor as a large wall was the target. Thermal cameras intended for temperature measurement include a “Distance to target” variable in the menu that the user configures. This paper explains why this can be an important menu entry when wishing to obtain accurate measurements at distances of several metres rather than at close range.https://iopscience.iop.org/article/10.1088/1742-6596/2520/1/012032/pdf(https://iopscience.iop.org/article/10.1088/1742-6596/2520/1/012032)This paper does not cover the effects of thermal energy flight path contaminants (water vapour, solid particles etc) in the air between the measuring system and the target so is a “best case” scenario with data collected in a lab environment.I have added the PDF file this post.Fraser

content: That was an interesting read ... for both the content and the choppy English conversion! This was an interesting take on how to compensate for 'range to target' signal loss. Looks like they basically just took a curve fit of empirical data as a way to avoid the typical atmospheric loss calculations. Depending on spectral band the losses can be very severe until the spectral windows start to fully form (see my Avatar). I've ran ModTran a lot across full spectrum UV to LWIR in increments of inches to kilometers. If you require accurate temperature then placing a calibration source at the same range as the item of interest makes data reduction MUCH easier. the higher the accuracy you desire the more you need to compensate during calibration and measurement.For a head hurting, put you to sleep, set of papers, then look up Nicodemus who worked at NIST in the 70's and 80's.Willers book "Electro-Optical System Analysis and Design: A Radiometry Perspective" has some excellent diagrams and a huge equation on page 281 that tries to account for everything between source and sensor.

I'd also like it to be able to work on its own, without having to attach to a phone or anything.I’m not a fan of the kind that plugs into a phone (like the FLIR One) — my phone’s pretty old anyway and probably wouldn’t work well with it.Aside from that, it should just be able to display decent thermal images on the built-in screen. Picture quality doesn’t matter a lot to me. If you know of anything that would fit those criteria, let me know!

Potential downsides:Does not act as a webcam via usb, only storing on SD card.Every so often the image freezes for half a second for calibration. I guess this is common to most such devices but don't know for sure for lack of comparisons.No manual min/max range setting, only automaticno firmware upgradesAs I said: it's a cheap device but does everything I need.

To my surprise, the moment i plugged the M7 init was actually 50HZ(as advertised)The device is round and bulky (compared to the P2) and it has a manual focus ring on the front.After consulting the booklet in the box, the qr code redirected me to an app calledPixfra SightThe image looks nice and clear, although it isn't intended for indoor use, and i didn't find any temp reading options yet.The 10mm lens offers a FOV of 17.5° x 13.1° (compared to T2 PRO which has a 13mm lens, 13.6° x 10.2°, and Xinfrared One XH09 (also 50HZ) with 9mm lens, 19.6° x 14.7°)

What is the TM code I keep reading about?Below $400 is my price point.Also looking at the $299 Thor002 with the good review here.. It seems the only thing missing from P3 is the manual focus and macro. Is it possible to repurpose other IR macros with 3d printing for something like the Thor002? I know the T001 has a specific menu setting for the macro.Only the old Topdons are on sale I think. I could be wrong, but it seems like comparable newer models are more desirable due to fast evolving tech.Any opinions? Anything else I sho0uld look at? USA

content: It is hard to ignore the new Thermal Master THOR-002. You get an awful lot for $299 (and a 5% discount is available and detailed in my review). It is fixed focus but a $20 close-up lens of your choice can be attached for PCB analysis. Manual focus can actually be inconvenient when out and about and quickly capturing images. You have to focus a manual focus thermal camera carefully to obtain the sharpest image. That said, best focus is achieved with a manual focus lens.I personally prefer a complete, self contained, thermal camera solution that does not rely upon a mobile phone host and an APP that can become “out of support” and stop working on later phone OS versions.Fraser
