Just received HTI HT-301. What Android device should I get? - Page 1

content: First off, I had no idea how tiny these phone thermal imaging cameras are! Neat!(I also had the naivete to believe HTI that they would be shipping from a "US location"... which last I checked that doesn't include Hong Kong.)That aside, the HT-301 doesn't work at all with my go-to cheap Android phone, a BLU Studio M6 running Android 5 (<-- perhaps the reason). The phone recognizes and sends a few hundred mAh to the camera, but it won't display any image - including with ThermViewer.So I'm off to Craigslist for an Android phone. What are some options for the most economical device that will afford me the full functionality of the camera?

content: Thermal camera image management and analysis software used to be an optional extra that cost several thousands of Dollars. Whilst that situation existed, there were 3rd party software providers willing to create cheaper (though still not cheap) software for a range of thermal camera brands. One particular 3rd party software suite was even sold under a particular camera brand as it was so good. The software was licence locked to the brand you purchased it for so not truly a universal solution.In recent years, thermal camera Manufacturers have provided free image management and analysis software.They sometimes offer “paid for” software for professional users who require greater capabilities.This current situation appears to have effectively killed the 3rd party thermography software market. I had a quick look and all of the thermography software I was aware of is now long gone.Fraser

Let's say that I want to back up the existing firmware on an existing camera.2. I install a new firmware update onto the camera, overwriting the original firmware.3. Then, using FLIRInstallNet.exe or an SD card, I'd like to overwrite the updated firmware with my original firmware using the FIF file I created in step one.Is this as simple as downloading all the files from the camera via FTP and creating a FIF file from that directory structure? Something inside of me tells me that isn't the case....especially as it pertains to some of the "protected" files....Hopefully I'm wrong

The installation will display a thermal view of the exhibition's attendees.- The interface is not important since I can capture in analog, HDMI, SDI or over IP.- The resolution shouldn't be that high, even 320px in width will suffice.- The price cap is quite low , around $1000.Is there any model you guys can suggest? Think of it as a thermal webcamI've been looking at a solution where I run the SEEK mobile app on a PC using an android emulator and then capturing the region of my screen that contains the video. This could work with a Seek Shot Pro which is plugged to power for the whole duration of the installation.But as you can see it's kind of a hacky way and I may face problems. What do you think?

But its also so cheap it does not have a mechanical shutter for calibration, so you end up putting the lens cap on and manually telling it to calibrate a few times until it warms up and becomes stable.If you ask them they will give you the driver library for windows or linux so that you can grab frames from it in your own software. The driver is pretty crappy but it works.

You can hear the sensor adjust from time to time and the laser pointer button works normal. I'm thinking the software must have got corrupted? It has no signs of physical damage. Also I searched is there any disassembly info available here on the forums (I searched)?

(simplified version)Loads OS from Flash memory into RAMRuns OS in RAM and self tests software integritySplash Screen Created (FLIR)OS tests hardware presence and looks for fault flags or nil responses from sub systemsOS loads calibration tables and user interface.Camera ready for user(Done from distant memory but gives you an idea of what is going on)Your camera may well be finding a hardware error and going into the ‘Halt’ state.One way to see what is happening is to monitor the engineering RS232 port on the main board and see the boot sequence progression and any error codes that are produced. If your camera has an external RS232 port, this will also provide boot information.The fact that the camera produces a splash screen suggests the main processor is working as that drives the graphics production. There are several camera sub systems that can cause a ‘Halt’ situation though. It would be worth changing the RTC battery or even the whole RTC chip as I have had those fail and ‘Halt’ the camera due to corrupt data in their registers that cannot be corrected (IC failure). The RTC memory is often used to hold camera hardware configuration information such as country specific data like NTSC or PAL video standard etc.I regret that I have not worked on a 300 series camera so all of the above was learnt from different FLIR camera models that predate the 300 series camera that you have.

Usually, the entire apparatus and techniques are dependent on the absorption and re-emission characteristics of the fluorophores.What's most interesting to me is the temperature dependence of the fluorophore intensity. It's pretty amazing that they can get 0.005K resolution. Given standard PMTs, it would stand to reason that the technique might require high intensity UV lasers? Do you know specifically how they get that kind of thermal resolution? It occurs to me that the fluorophores would saturate across a very narrow window with that kind of thermal resolution...Also, do you know what kind of linearity there is between the fluorophore temperature and the resulting photon emission?

My T440bx can, but I never use it due to how awful the image quality is.They're worth getting if you can get them at a low price. The T3 series performs about as well as earlier Exx, the T4 outperforms the Exx in terms of image quality, but not by much. Autofocus is about the same - mediocre, but rather accurate.

Looking for a thermal sensor or camera for less as many here (p.s don't mind used sure, pm me) however the DIY sensors are really subpar and the damn Flir are keeping their Monopoly with the lepton really high priced.Anyway,I stumbled upon these searching online, also knew that amprobe is kinda part/Ally of fluke for tight budgets.The 110 model has no sd card or saving mechanisms, however the sensor resolution is really high for a 200$ product.The 120 have all the bells and whistles, including saving data etc.Have seen scattered YouTube reviews..The Irc-120 looks really interesting but display is really small (can it be modded to have an external supply connection?)What do you general think of these compared to the common mobile USB Flir/seek thermal.I need to experminte with thermal pads and modding for GPUs and I wanted to heat map lots of concepts + find weak spots, heat accumulation and I think anything below 100*100 is a no go.Regards,Nabil

content: The Chinese like to play games with specifications.You must look carefully to spot the tricks in the specifications but the classic one relating to resolution is to state the visual camera resolution and display resolution but not the actual thermal camera resolution or pixel count. The camera you have referenced appears to be a classic example of this and the sample images Suggest to me a camera using a 128 x 128 pixel visible light image overlayed with something like a 32 x 32 pixel thermal image that has been interpolated and up-scaled to match the visible light image.Always ensure that you know the thermal image true optical resolution and do not settle for a ‘displayed’ resolution as that can be a low resolution thermal image that is interpolated up to any size the manufacturer desires.It does Amprobe no credit that they have partnered with a Chinese OEM who plays these games and actively avoids revealing the thermal imaging array resolution. Just read the ‘non-free sample’ reviews on Amazon to see what you would get for your money.Fraser

content: From what I know of them, the Therm App and Thermal Expert use different diameter threaded lens mounts. I cannot comment on the XTherm as I do not know its lens mount details. The lens needs to fully illuminate the Microbolometer pixel array so check the dimensions of the originally intended FPA compared to the one you want to use it with. Some cameras use ‘commercial off the shelf’ lenses so you can look up the datasheet for the technical details.You also need to consider the back focus distance if thinking of adapting a primary lens to fit another camera. The back focus can be different between cameras with and without an FFC flag. Cameras with an FFC flag can require a greater backfocus distance to accommodate the thickness of the FFC flag assembly. Whether the threaded mount of a lens enables adequate adjustment to use a non FFC flag camera lens with an FFC flag equipped camera is a possibility that would need to be investigated before purchase.Fraser

The corners will either be brighter or darker.Same applies looking skywards at an even cold scene.Bill

content: Hello guys.I want to find a MWIR camera for my friend, which need:1. If it's cooled, it need to be a closed loop cooler, no requirement of adding cooling material continuously;2. Have live-view mode, not snap-shot only.And better to have the following, although not absolutely nesserary:3. All-in-one, no need to get seperate controller/monitor/battery, etc;4. Minimum resolution of 100×100;5. Minimum HFOV of 25 degrees.I remember I saw many of those like FLIR PM or AGA on ebay years ago, but many I can find now are LWIR after Googling, and some even have both LWIR and MWIR for the same model number?! It's really confusing...Thanks for any advice.

content: You may wish to read this post on cooled cameras.....https://www.eevblog.com/forum/thermal-imaging/thermal-camera-purchasing-the-perils-of-buying-a-cooled-camera/Cooled MWIR cameras are uncommon and a relatively risky purchase compared to uncooled thermal cameras.Please also be aware that most closed circuit cooled cameras are also quite heavily regulated with regard to export controls.Models with closed circuit cooling that appear on eBay include the following g:AGEMA THV900 - scanner type with external controller. Old so cooler could be dead.AGEMA THV450/470 scanner type with internal controller. Large and uses multi-stage Peltier Stack coolerAGEMA THV550 Cooled Staring FPA in camcorder style housing. If working these are normally expensive. One recently sold for almost £3KI cannot recall any closed circuit cooled AGA cameras. They used Liquid Nitrogen. In case you are unaware, AGA became AGEMA.Inframetrics produced some scanning type closed circuit cooled MWIR cameras. They have an external controller. Models to investigate are in the 700 series. These sell for relatively low sums of money but do check if they are working. Look for the Inframetrics 740 or 760 on eBay. They come up for sale quite often. I just bought an AGEMA 470 for £100 but that will need some restoration work due to age related deterioration. Whatever your friend looks to buy, he needs to see pictures of it producing a thermal image, not just a boot screen ! A unit with a dead mechanical cooler is basically a paperweight with no simple way to fix the cooler.Fraser

The window looks like germanium. Markings on the back of the PCB are 070510 and TP46 (no relevant hits to the latter). There is a resistance of about 138K between the pins, independent of polarity.Click on image to expand. Any guesses as to the exact identity?

Thanks very much for the links.The one pictured above outputs only about 0.7 mV (measured with a 10 Meg DMM on the 200 mV scale*) when pointed at a full field source at 100 C, so it doesn't seem to correspond to any of the offerings in the link by TE.(*)Am I correct in assuming that VTPis essentially an open circuit voltage? As mentioned, the internal resistance is 138K.

content: Hi,answering your questions:1) Yes, it delivers 30Hz, exactly not more and not less. BUT: only on a PC, on my phone which may not be the fastest (2GHz Octacore) it only get somewhere around 15Hz. I did not measure it exactly but it is a bit faster than the Q1 some significantly slower than 30Hz. The issue here for me is the crappy TE App - it's Java, it's not really optimized and just slow. On a PC, even on very low end tablets like an Atom Z8350 powered Dell Venue 8 you will get 30Hz.2) Build Quality (mechanically and detector-wise) is the same as the Q1. I had pretty good detectors on both Q1 and V1 (see link below for dead Pixel maps). Although the first V1 I got had some issues, like scratched lens, used case screws and lots of dead-pixels - the distributer exchanged it and the second on was perfect. Mine currently on has 141 dead pixels - less than my Q1. Noise and sensitivity (visually) is the same.Maybe this thread may help you in some regard:https://www.eevblog.com/forum/thermal-imaging/thermal-expert-te-v1-vs-te-q1/msg1797836/#msg1797836If you have any other questions you can also PN me.RegardsToni

content: regrading your question about similar cores. ThermalExpert also sells the V1 and V2 as a OEM core and not phone dongle. The prices are a little higher but it might be something for a project.FLIR Boson 320 can be found cheap, always have an eye on Groupgets. But also see through the threads that critize the performance. You may get lucky and find a working core on eBay or can harvest one from a camera. It can save money but it's more effort and there are unforeseeable parameters.

content: You're doing it wrong. That sets the calibration range, or the "gain." You don't need to be in the settings menu. To adjust palette min and/or max, just press the "OK" button while in camera mode. A menu will come up with "Auto" selected. If you press the right arrow, each successive press will then change the palette to "Manual" then "Manual min" then "Manual max" and these are pretty self-explanatory.In "Manual" you can move both ends of the scale up or down with the up and down arrow keys. You can make the span between the min and max greater or lesser with the left and right arrow keys.In either of the other manual modes, you can adjust the manual end of the scale with the up and down arrow keys. The opposite end of the scale will float to suit the min or max temp visible to the camera.

content: The T1K has higher resolution and therefore bigger sensor. Given that the focal length is 36mm for the 28° fov (if the datasheet is correct) you get a much higher angular resolution with it than both options of the T650sc. However you have to ask about close focus, as tiny targets might need a lens that works in a microscope fashion. I am not sure if the T1K lenses support that.

I can find the options for the programmable button, but can't for the life of me figure out how to change one of them to save! I think bud had great success with the E4 hack, but I'm not sure it is suitable for the T620.Does anyone have any ideas if this is possible without having to nag FLIR to modify an end of line camera?
