I don’t know what gear you are currently using or how much it costs, but calling 384×288 “very low resolution” is unreasonable.
A typical thermal sensor resolution scale would be something like: 160x120, 256×192, 320×240, 384×288, 640×512, 1280×960 and above. So the question is: which resolution would you call “normal”, and how much does that level of equipment cost?
Regarding the “Hmm” video, surely the author could provide side-by-side comparison footage from the NordForce and from his other thermals that are not “Hmm”. It would also be helpful if he could state what those other thermals are and how much they cost, so viewers can make a fair comparison.
