We have perfected this over the years, ending up with the 960H 700TVL 1/3" Sony CCD image sensors, a matt white finish painted stainless steel bracket/hood to resist rust, 2.8mm wide angle 120 degree lens for the reversing/parking camera (to give a wide view).
This model is fitted with a 4 pin aviation connector (the standard type you mostly see today with the spin locking connectors).
