Mine are night vision with IR, and it works well.
As for range, I am not sure what you mean, but it states - of the top of my head - something like 10 meters. Practically, though, I have no problem seeing the same distance as I can in daylight.
MD with IR is probably more limited, though.
Cables are 15 meters.
