If the camera does as advertised I should have some 1280x960 images pretty soon. I know of a 1280x960 native detector that is available to the “general public” but it is super expensive and it is just the core. No one has put it in to a portable system yet to my knowledge.
Testo has the technology patented but I still think the others will figure out a way to do something similar. Fusion (it’s still a trademark of Fluke) was patented, yet everyone has digital cameras with PiP, side by side and blending of IR and digital these days.
