The 5x5mm camera is by far the smallest I've ever seen and the image quality is impressive for such a small sensor. The lens is supposed to be 3.6mm. It can be powered from 5.5V to 12V (a 9V battery with a DC jack is perfect). I used an USB grabber to test the NTSC composite signal, as expected the best results are with a resolution of 720x480 @ 29.97fps (it would be 720x576 @ 25fps in PAL). I also tested it directly on my TV with a RCA peritel adapter and it works perfectly. Next will be to test it in a FPV system. Also, shipping was fast and the camera comes in a little box with antistatic bag.
I checked All functions. this is an epoch-making product. The image quality is the same as the home video of the 1990s, but can shoot even with the brightness of the full moon. Color and monochrome are switched automatically. sharpness is high, can identify a person at a distance of 5 meters. Recommended for crime prevention in tight spaces.
