These DVR kits include a high resolution 550 TVL Sony Ex-View HAD CCD that
can work in near darkness (only 0.01 lux). They don't require any infrared
LEDs, which can cause a reflective glare off glass, and so are ideal for
use inside cars. The 12V motion detect DVRs can be powered direct from a
car cigarette lighter and can power a camera directly hence negating the
need for an additional power supply.
