- jcims 6y agoThat and the associated optics. There’s some reason for encouragement however. I bought a Seek Pro, with 320x240 resolution, on sale for $350 earlier this year. The app is pretty terrible unfortunately and the camera physical construction is flimsy, but the imager seems to be of reasonable quality for the price point. Couple of examples: https://imgur.com/a/ZGsOwUm https://imgur.com/a/ZGsOwUm
- garaetjjte 6y agoSeek cameras are rather noisy though. More expensive, but much less noisy and still reasonable to buy as a expensive toy would be TE-Q1 from i3system: http://nicesuper3.cafe24.com/down/TE-Q1-compressed.pdf http://nicesuper3.cafe24.com/down/TE-Q1-compressed.pdf
- jcims 6y agoLooks good! Any idea why they make it so difficult to buy their product?
- garaetjjte 6y agoi3system is based in South Korea, and I guess shipping thermal imaging technology is PITA due to various restrictions, not profitable enough to sell to individual customers. There seems to be EU reseller (thermalexpert.eu) but they sell only to companies (likely because VAT accounting when selling exclusively to companies is much easier).
- ampdepolymerase 6y agoThermal imaging resolution is restricted by arm control laws unfortunately. There are forces at work beyond market forces.
- jcims 6y agoITAR compliance assurance isn't free and certainly impacts operational costs, but the sensor I have isn't export controlled and still normally costs >$1K when you buy it from FLIR.
- benhurmarcel 6y agoThat's only for the US though, and I'd expect such a product to come from Asia.
- jansan 6y agoI once rented an IR camera for roughly 100€. This is probably the best option for people who only need IR cameras on very few occasions. Will we ever see chap(ish) IR cameras? Is there an alternative to germanium lenses on the horizon?
- jcims 6y agoI believe there are some metamaterial-based approaches for the actual microbolometers that should help drive costs down. Ostensibly metamaterials could also be used for lenses but I'm not aware of anything there, we're probably stuck with germanium for the time being.
- CamperBob2 6y agoZinc selenide lenses for laser cutters work very well in the spectral range covered by consumer IR cameras. They are dirt cheap on eBay, Ali Express, and other places.
- giantg2 6y agoThat carboy is pretty hot.
- gandalfian 6y agoYes I do covet them. Getting cheaper but still fairly low resolution. Keep hoping for a tipping point like digital cameras where cheap decent sensors will suddenly be everywhere. Not yet though.
- jstanley 6y agoI bought one on eBay a few years ago for about £300, but it sucked so I got rid of it. It used a traditional camera to draw most of the image (itself already quite low-res), and just highlighted even-more-low-res temperature data in blue and red.
- SoSoRoCoCo 6y agoI was just considering buying one. Would you share your thoughts?
- jstanley 6y agoThe resolution was too low. I didn't really have a use in mind for it, I just thought it was interesting and thought I'd find uses for it after I owned it, but the resolution was too low to be able to do anything useful. Here's the only picture I have of it working: https://img.jes.xxx/1047 https://img.jes.xxx/1047 As you can see, you can't see anything.
- SoSoRoCoCo 6y ago> As you can see, you can't see anything. Thank you. I wanted to get one to (a) find creatures outside at night while camping, and (b) fix my house energy leaks. But that rez seems awfully low. So amazed at the OP for doing such an amazing job stitching images!
- dheera 6y agoI've had decent luck finding and seeing creatures with the Seek RevealPro I used, although there may be better ones out by now. I even used it to try to find a friend's lost cat once. I didn't succeed in finding the cat with it, but I did end up finding a few other stray cats and racoons. (For anyone wondering, the pet cat was found later and was taken to a shelter by some good samaritan.)
- freeone3000 6y agoFor (b) even a quite low res thermal camera can be useful. Compared to a laser thermometer, you have a much wider fov, and you can always get closer.
- soared 6y agoI'd imagine demand for thermal imaging has skyrocketed due to covid, so its possible the tech will get better and cheaper.
- CyberDildonics 6y agoI don't think cheap cameras are sensitive enough and you don't need an entire image that is better for seeing relative heat, you just need a single accurate reading. Those thermometers are only $20 and are being cranked out in bulk.
- SoSoRoCoCo 6y agoIt's $570: https://www.amazon.com/Seek-RQ-AAA-Thermal-Revealpro/dp/B07B7N4DLV https://www.amazon.com/Seek-RQ-AAA-Thermal-Revealpro/dp/B07B...
