content: Just saw this guy in today's BangGood hot deals (see title)US$389.99 for a 320 x 240 imager, that sounds almost too good to be true?I have strictly no idea what it's worth and I'm not even on the market to buy a new device, so I'm just passing along. Maybe it can interest some of you guys or maybe you'll tell me it's total crap and that will help other members not to fall into this trap!PS: you might see a different price since I think I'm at the highest level of their VIP advantage program

content: I was just looking at this imager yesterday...Based on the noise style in the video below I would say that it has SeekThermal core inside.And it looks like SeekThemal is still providing fake images to promote their modules:Marketing (Thermal images from 50,000$ camera):Reality (taken from the video of actual device):Resolution is not all. If core is crap and lens are tiny and all you can see is noise then pixel count also does not matter...

content: I have found it on Seek website. It seems to have C306S or C306SP core inside (visual match to 320x240 9fps core).https://www.thermal.com/mosaic-core-320x240-6mm.html

content: Alex, Frenky, did you end up buying/testing one of these? I've recently been looking at cheap thermal cameras with 320x240 resolution and this one came up. Just wondering if it's worth the money or just junk. AliExpress has sellers offering this for around US$110. Hard to beat that price.-RoB-

content: Quote from: frenky on February 15, 2022, 10:08:04 amThe processor seems to be a bit sluggish here, the image freezes every few seconds. It won't calibrate that often? It is also always popular with these handhelds to simply save on the inner workings (CPU, RAM, etc.).Quote from: frenky on February 15, 2022, 10:08:04 amThese pictures were taken with a resolution of 640x480 but it doesn't need $50,000 for that. You can achieve this quality with any core, it all depends on the thermal contrast.I personally avoid such "honeypots". If you look at the quality of the more well-known UniT devices, for example, then I don't want to know how much worse it can get.

content: Looks like a Hti HT-19!I am pretty sure it's a rebranded HT-19. Here you find a few image-samples:https://www.amazon.com/Resolution-Infrared-Included-Lightweight-Comfortable/dp/B08CGZKV5R#customerReviewshttps://www.sevarg.net/2022/08/14/hti-ht-19-thermal-imager-review/https://www.eevblog.com/forum/thermal-imaging/hti-instrument-ht-19-(320-x-240)/I would say the image-quality is not really better than a Guide PC210, Hikmicro Pocket2/B10/B20 or Infiray C200/C210...In some cases technologies like iMIX, MIF or Hicmicros Fusion would give you maybe even better details with the lower resolution cameras.The 320x240 look on paper really impressive but the grainy sensor of that camera is not really great.
