This is an 12mm Shot with a C-Mount Professional CCTV Surveillance Camera
The same camera switches from color
to black and white with the overhead lights off. The camera automatically adjusts to lower light levels, as low as .001 Lux!
In this case, and light from a nearby exit sign was enough to allow the garage camera to ‘see in the dark’.
