content: Hi all!I have a Flir T400.I decided to upgrade the firmware to v9.4.5.The update took around 15 minutes and was sucessful.But after this update I noticed the digital camera is very 'jumpy' and fusion mode has lost it's colours (only in black / white background)When Fusion mode is switched off the camera runs smoothly.It also looks like fusion mode shrinks the IR image and there is an offset when focusing.Does any one know what could be wrong?

content: I upgraded an Flir B360 and saw similar behavior.The visual camera was shown in full resolution and color. But in Picture in Picture and other "fusion" modes, the visual Image is cropped to fit with the thermal image. If you focus, the visual image is shifted to compensate for parallax issues.Additionally, it was converted to grayscale, therefore each color like red or blue comes from the thermal image, not from an object in front of the camera.

content: Picked up a Seek compact XR because i wanted one to mess around with and since i can expense report it why not?So started i wanted to see some components "0201 and 01005 surface mount stuff" Did that pretty easy. Then decided to how good i can get a 350X350um component. After some work and testing some quantum pla i made my part and tested it out. And its great. Picture sucks because im holding the gel pack with the part over the lens since i don't have the mount at home so Tuesday i'll do some real testing and get everything set up. This was more of a test to see if it is possible.Based on known feature sizes i can just make out 20um. When i power it on im sure i will be able to see that a bit better.Not expecting amazing things from this. For what i got it for it works great and the image quality for that is pretty good. But seeing how far i can push it im pretty impressed.

content: I have a thermal imaging weed growing but am ignorant of class of products here. Surely, I want the Goldilocks' solution.Typical home hobbyist uses like T-shoot PCBs, appliances, home leaks, fun, and general learning. Ido not want a cell phone dongle.I saw the Ames model for $200 at HF in the US. 32x32 sensor seems pitiful, but it also looks like it might do some of the stuff I need.But money is only a small object. I can spend more, but not too much. I'm not spending a grand, so maybe up to 500 if there is a decent jump in features or, I like performance, resolution, depth (dynamic range) type metrics... i.e., I care less about things like multiple temp cursors on the screen. hi, lo, center is probably just fine, and commercial productivity concerns are not important to me. Video record might be nice. I would like to see the live image on my PC too.Maybe the UniT260B? The ebay sellers either have low feedback (~1100) or are gouging.If I buy the Ames on my way home, I won't buy any other one later and will have to suffer with what I get.

content: The Ames is pretty scuffed if you actually wanted to troubleshoot PCBs. Please see attached images for the same PCB being imaged by the Ames compared to HTI Xintai HT-19 (320 x 240). I got some 20 mm dia ZnSe lenses for it to do PCB repair, and I'm fine with the performance. The fact that it's portable makes it easy enough for me to bring it to work everyday and just use it whenever a thermal image might help.

content: I have a 80x60 9Hz Multicomp Pro that I got very cheaply (<$100) and although I'm happy to have it, it is at the bottom end of the useful range. It focuses fairly close so I can scan near the PCB or item of interest and the temperatures do seem accurate. And even with the 9Hz refresh rate, it seems to react promptly and doesn't seem laggy. But going down in resolution from 80x60 would be intolerable, IMO. At least it would make any sort of work with SMD nearly impossible.

Old FLIR EX320 Replacement - Streaming Video to TV/Monitor Display? - Page 1

content: For years I've run a thermal imaging demo for kids events/outreach with a ~20" LCD display running RCA video streaming from an old FLIR EX320 camera. I fired up the camera this week and found that the image had a number of horizontal bands/poor resolution but the menu was perfect. For better or for worse, flexing the camera would somewhat straighten out the image momentarily but it would revert as soon as it was released (light pressure). I pulled it apart and found a large ceramic capacitor dislodged from the power board (not in the case, might have happened long ago) but otherwise it seems to be in clean shape. I reseated everything, reassembled, and now it's even worse than it was before :-) I'm going to take another stab at repairing it or at least determining the cause of death but:Long story short - I was contemplating a new FLIR E4 and hack upgrade it to E8 so I have the same resolution, but in looking through the forum there's a lot of better imaging options out there now (resolution and frame rate). I'd like to spend <$1,000 on a new camera,what should I buy if my principal need is streaming video I can display on a monitor or Windows computer?(or rPi, something standalone and easy to set up/keep working like a webcamera stream, etc). I should also mention a preference for something with 10+ year standalone capability, if it relies on a particular phone/OS/etc it's bound to be a PITA someday when the OEM goes under.

There's also some Youtube clips from resellers that seem to look alright, but again I'm not sure how objective they are, eg:I've been considering one of their industrial imagers (348A) as an off the shelf setup to avoid hassles with setting up something from a thermal core to save time/expensive mistakes. It also offers autofocus which would be mighty handy for some imaging work! Usage would be primarily engineering inspections and 'thermal photography'.Cheers,Marcus

I've only found two video reviews so far, but there's no guarantee of impartiality because both reviewers seem to be distributors.

content: Great to find this forum to discuss thermal imaging . I am from China, I can hardly find a technical forum to discuss thermal imaging on the Chinese Internet. There are some small forums, but they are all focused on thermal imaging for hunting.Here I get three thermal modules from IRay (or InfiRay). The model of these modules are LB3230 and FT384. LB3230 is a very early module of Iray. I can't find its specification. But some key information can be guessed from its model name. The resolution may be 320 * 240, the pixel pitch may be 35um (IRay's first thermal detector pixel pitch is 35um, then 25um/20um), and the frame rate is 50Hz (according to my test).The other two modules are both FT 384.but they have different thermal detectors,RTD311 and RTD3171MR,they both have 17um pixel pitch.RTD311 is early than RTD3171MR,and RTD3171MR can find on IRay’s website.The user extension board have different interfaces.LB3230 only have a HRS socket for power/rs232/video.One of the FT384 have two focus/zoom sockets,the other have digtal video output sockets.

content: Great showcase. Especially looking through the window and seeing how much smaller the actual die is. The shutter flag looked like it was blocking the corner of the image if you don't know the specifics.Having a smaller resolution version window was seen on other devices like the TE-M1 from ThermalExpert but I don't believe we ever found out if those were two different detectors (as they moved the window to the center via a software update).As IRay has since made 12μm and even 8μm sensors, it would be very interesting to see how much their packaging technology has advanced in this short time.

content: This might be interest to some of you (even if it does use the "lowly" FLIR Lepton 3.5). For the past couple of years I've been designing a wireless thermal imaging camera using the ESP32 and Lepton 3.5. My goal was to be able to make radiometric data available to people. The camera is designed so that various applications, including custom ones written by users, can connect to it via a socket interface over WiFi and use the data for a variety of purposes. In that sense it is a little different than the traditional thermal imaging camera. However I wrote a companion desktop application (running on Linux, OS X and Win), and an iOS app for iPhone/iPad (hope to have an android app later this year), as well as a python driver. The apps allow visualization and temperature plotting (desktop app). Other people have written Matlab and R drivers for getting the data into those environments.The original design could be built using an ESP32 dev board and Lepton breakout from Group Gets. I also designed a PCB version and partnered with Group Gets to get it built. They have just finished the first run of the new revision 4 PCB and it's available on their website as two models (links below). Full disclosure: I do make a small commission on their sales but I'm not going get rich off this. Mostly I just wanted an easy way to share my work and they're a distributor for the Lepton so it was a good fit.https://store.groupgets.com/products/tcam-mini-rev4-wireless-streaming-thermal-camera-boardhttps://store.groupgets.com/products/tcam-mini-rev4-external-antenna-wireless-streaming-thermal-camera-boardThe design can be found on github and some files more easily downloaded from my website.https://github.com/danjulio/lepton/tree/master/ESP32https://danjuliodesigns.com/products/tcam_mini.htmlI've also been documenting my experiments with the Lepton over the years on hackaday.io. Mostly before I learned of this great resource.https://hackaday.io/project/159615-lepton-35-thermal-imaging-camera

content: HiI am looking for small modules with 384x288 or 400x300 resolution. RS232/I2C for camera control would be nice. The module should do all the image processing magic internally, I do not really plan to do postprocessing on the data. I do not really need radiometric modules, if possible I would go for non-radiometric as they would be cheaper.I will integrate it in a quadcopter (therefore it should not be too heavy) for locating fawns in the grass. I know that there already exist "dedicated cameras" for this purpose, but they often seem overpriced for what they can do. And apart from that, I like building drones and integrate all sorts of electronics on themOf course there is the FLIR Boson, but not all people are too happy its performance when compared to the price. There are some interesting Chinese manufacturers. Infiray, Guide Sensmart and Global Sensor Technologies. However, the latter two seem to have exactly the same products, with the same model-numbers. Both based in Wuhan, but definitively different companies.From GST/Sensmart the interesting modules are (12/17um):COIN412, COIN417, PLUG412, PLUG417From Infiray some are named "LWIR", but they all their products are specified to have 8-14um spectral range. Modules (all 12um):Mini 384, G1 384, Micro III 384, NanoⅡ 384- Are the modules listed above suited for the applications?- Do you know better suited modules?- What would be your preference?- Does anybody has some background info regarding Guide Sensmart and GST? Why do they sell exactly the same modules?- Experiences with any of the modules above?Thanks

content: Hi,I own a HIKMICRO B20. Have wrote about it a bit here:https://www.eevblog.com/forum/thermal-imaging/hikmicro-b20/msg4047262/#msg4047262The Uni-T devices take more than 20 seconds to start and when changing temperatures (-20-120°C to 120-550°C) it takes over 20 seconds again. This shows that a very slow processor is installed. Things have their price!The HIKMICRO B20 have 25 Hz and it appears that way when panning. Start time is 8 seconds. With the software update since December there is also the option of changing the palettes as a shortcut without first having to go to the menu. But for most settings you have to go in there first to change something.The field of view (FOV) is a bit wide-angled. This is also a quality thing about a thermal imaging camera in addition to the processor and of course the sensor.The sensor is quite good so far, the sensitivity is high and the device is more than sufficient for home inspections!No touchscreen here and the display looks like its a cheaper one with only 256-bit colors. The sensor has "only" 256x192 resolution - for a 384x288 sensor I would have to pay 2.700€ for the device... Have a look into my thread for some examples.Fraser once took apart a similar device from HIKVISION (belongs to HIKMICRO) and found the quality of the components to be very good - in contrast to e.g. the Uni-T devices.Since I don't know the M200A, I can't say anything about it.

If you can change the gain setting of your camera, you may get more of a dramatic shift if you could restrict the dynamic range of the scene to maybe half or a third of what it is here - centering around the temperatures you expect that day with some excursion on either side should make the change most visible.

Which FLIR Photon has the model number 412-0035-21-07? - Page 1

timestamp: April 03, 2022, 11:03:45 pm
content: I was looking on eBay for FLIR thermal cams and found an old one, a Photon. Unfortunately the seller didn't leave the specs or even the model number. Fortunately he did have a cellphone-cam captured screenshot of the Photon GUI on his computer screen, showing the part number (which I assume is the same as the model number). That number is 412-0035-21-07. Unfortunately a Google search for that exact model number turns up nothing other than search results for thermal cams with SIMILAR part numbers. When I do the search for 'FLIR "412-0035-21-07"' (with the model number in quotes, to force Google to search for that exact string), it says 'No results found for flir "412-0035-21-07".'. So that means that apparently this exact model number doesn't exist, or somehow Google doesn't know about it. Below the message about that exact search turning up no results, is where it shows results for flir cams with similar (but not identical) model numbers. So the only thing I can assume is it's such an old model thermal cam that Google no longer has webpages about it in its database of searchable webpages.All I want to know is what is its resolution, what is its framerate, and what is its field of view. I hope someone here with extensive FLIR Photon knowledge can answer that.

content: BST is dead and buried now. There was an attempt at a new ferro-electric detector by Raytheon but it came to nothing.If we look at things in 2005:NeTD not that far apart, similar pixel sizes and therefore lens costsBolometers needed a lot more image processing.Bolometer uniformity was bad, while BST is self correcting for column patterningBolometer dead pixels were higher (even with 50µm pixels)BST more tolerant on bias noise, higher basic thermal responseVOx was not compatible with mainstream fabrication so higher cost (2x BST)Flags and choppers were about as much of a pain as each otherBoth needed TEC temperature controlHowever in 2022 .....Image processing is cheap and low powerBolometer uniformity has improvedBolometer dead pixels have improved despite smaller pitches.TEC-less bolometers give good imagingEnough volume for dedicated VOx processing lines to be as viable as standard siliconBolometer pixel sizes have reduced, I doubt that BST would have been able to shrink in the same wayFlags have got smaller or been eliminated.Bill

content: I have met FAT12 being used on small capacity CF cards. It would be worth using an earlier version of Windows or a formatting utility to try FAT12. FAT12 is more commonly found on floppy disks but early CF cards of small capacity used it as well. Any CF card with a capacity of 16MB or less may be FAT12. Over 16MB and it will be either FAT16 or FAT32.I tend to use 256MB CF cards in my FLIR cameras and they work fine with a FAT16. Anything larger than 512MB can cause the card to be not recognised on my FLIR PM series.Fraser

Is it possible to do that ? I don´t have a Firewire port on my Notebook.Besides radiometric videos, is hacking possible to generate UltraMAX, MSX and other hidding features ?I read all the E40 hacking posts. I noticed by the files extracted from the P620 (conf.cfg, gui.cfg, etc) that some are disabled.Thanks in advance.Cardoso.

content: Hello everyone on the forum,I'm based in Vienna, Austria and doing drone work for a scientific research project at the moment.I recently purchased a FLIR Vue Pro R radiometric thermal camera. The software for radiometrically analyzing the still and video files from the camera is done with FLIR's proprietary Thermal Studio software. However, this is pretty expensive and MS Windows only.From what I've read so far, file formats for radiometric image files are mostly proprietary and not open source based.Can you point me in the direction of an alternative or FOSS software for these specific files? That would be very much appreciated.thanks,GebhardLinks:366 https://www.flir.eu/products/vue-pro-r/]https://www.flir.eu/products/vue-pro-r/]366 https://www.flir.eu/products/vue-pro-r/https://www.flir.eu/products/flir-thermal-studio-suite/?creative=549408328069&keyword=thermal%20studio&matchtype=p&network=g&device=c&utm_campaign=emea.de.solutions.cmprem.t.aw.om.cm-phh-thermal-studio.search&gclid=CjwKCAiA1JGRBhBSEiwAxXblwY4xq1LcrqK2TrsblWBYrl2aD2y7Nmm3xA3CPvoQ-bW5r6uymWv0PBoCL7cQAvD_BwE

content: Hi,I have a couple of MR277 Flir Thermal Imaging Moisture Meters.Both seems to have an issue with ambient temperature measurements.Everything stars out fine and the temperatures are "close" to my Fluke's. But then the MR277 slowly starts to show temperature increases - and drifts to 4-6 deg C above the Fluke's. The increased temperature readings stay after power cycle. But if one leave the MR277 to cool - after about 1-2 hours temperature is "back down" to Fluke levels.Fluke support say it might be "calibration" issue - but I'm not quite "happy" with that answer.Apart from that the MR277 are really nice for moisture detection and humidity measurements! I bought them for boat and building diagnostics. But if ambient temp is off - everything else is off...

Is the HT-H8 really a true 25Hz thermal imager? - Page 1

timestamp: February 24, 2022, 06:37:23 am
content: I've heard HTI makes good quality thermal imagers, however after I watched the official demo video for it hereI noticed it seems to have a much lower framerate than the claimed 25Hz. Also, it seems to have significant lag. And I don't mean for the wifi streaming video feature. I see there's quite a time delay between when the imager moves, and when the image on its screen moves. Is this just a prototype version they are showing in the video, or maybe a 9Hz limited-features version that they sell to countries they don't trust selling the full version to? Or is this actually the best capabilities of the the HT-H8 thermal camera? If anybody here has used an HTI HT-H8 thermal imager, please let me know about your experience with the device.

content: Quote from: Ben321 on February 24, 2022, 06:37:23 amThere is indeed a lot of pipeline delay, can be fairly endemic on cameras without a lot of highly specific hardware or with an operating system in the way.Whether it is 9Hz or more is really quite separate. You can still do 25 images a second delayed by 3 seconds if you have a 75 frame pipeline !If fully designed for 9Hz only, rather than cut to 9Hz near the end, you could design to reduce the pipeline as there's more spare time when nothing is going on.Bill
