After the discussions regarding thermal cameras in another thread, I noticed that Hackaday just added an article talking about this video:
Where the guy is checking out the Thermal Master P2 USB-C thermal camera:
US$250 - 256x192, 25Hz, 56 degree horizontal FOV
US$350 - As above but with a removable macro lens
The P2 Looks like a smaller version of the phone-connected Seek thermal cameras that have been around for a while. That prompted me to go looking at the Seek series and they’ve updated theirs quite nicely. They have a cheaper lower res option or for the same price you higher 320x240 resolution. Both have the option for a macro lens. The Seek unit has a minimum focus distance of 30cm so the addition of the macro lens is nice, although I don’t think I ever really use our work one much closer than that.
US$150 - 200x150, 25Hz, 35 degree horizontal FOV
US$250 - 320x240, 25Hz, 56 degree horizontal FOV
One thing I thought was interesting was that he was comparing it against a multimeter with the camera built in:
That’s cheaper than both options and has free shipping. Appears to have image saving and USB camera output capability. The guy mentioned it having a macro lens attached but I couldn’t find any info on whether that came with it or not. The image looked a lot better on the P2 but I suspect that’s just some software trickery and sharpening to display it on the higher resolution phone screen.
US$141, 192x192, 20Hz, 50 degree horizontal FOV
The same brand has something that’s basically the same as the P2:
US$140, 256x192, 25Hz, 56 degree horizontal FOV,
US$26 macro lens
Interesting to see so many good options with them getting cheaper and cheaper. 25Hz being standard now is awesome, too. I think both of our work ones are 9Hz due to export restrictions at the time and it makes a surprising difference to how frustrating they are to use, especially if they have a manual focus.
