It looks like a veritable stampede of new players in the thermal market.

I just noticed and am surprised that the 640 version with nearly 3x the resolution (327680 pixles) has less than 50% better overall detection, recognition, and identification capabilities of the 384 (110512 pixels). Is that the same with other thermals?
