Excellent video and explanation.

What's the refresh rate

I tried using your coupon code at Banggood to purchase the HT-19 but it said it had expired. Do you have another code?

I have one of these and the image quality is nowhere near the claimed 220×160. My FLIR TG-165 gives better images than this does and that is only 80×60. I've tried various settings but never get anything other than a blurred thermal image. I suspect the lens is the issue but it is not adjustable.

Very interesting and informative video. Thanks for sharing.

Interesting, well made videos as always. A little off topic, but would you consider making a video(s) about your digital clock and/or calendar that appeared in this video? They look great!

Thermal cameras are actually really handy in troubleshooting electronics. Finding faulty components and ICs. For this amount I would rather buy a FLIR one, which can be used on a smartphone.
