This is pretty neat. It's some sort of CCD or CMOS color imager. It's not as sensitive as a Gen1 tube, but it's pretty good. It seems to be very sensitive to near IR at 850 nm, and also to my UV flashlight, 395 nm. Gotta try some more wavelengths.
At its lowest illuminator setting, it lights up a room just fine. I'll have to wait til dark to see how it does at distance. Maybe I can peep some raccoons or skunks in the back yard.
Resolution is good, better than my Russian Gen1 imager. It takes still snaps and stores movies in the micro SD card that was included.
It won't webcam, which is a disappointment.
