They use a 1/3" Sony CCD sensor and this is aided by high quality circuits for processing the signal. It has 12 IR LEDs to help with the night vision. It is designed to fit the vertical wall at the rear of a vehicle with the cable fed into the body underneath the dome. It uses the 4 pin aviation style connector and we have a number of kits available that use this camera. It should be noted that when on a vertical surface the camera when adjusted down sees withiin about 1 foot of the vehicle bumper.
We occassionally have clearance versions at a discount. THEY MAY BE OF A DIFFERENT SPECIFICATION. They will be on clearance usually for paint marks, new customer returns (change of mind) or old stock. Also they may be of a lower specification like a mild steel bracket or Sharp 1/3" CCD sensor at 420 or 480 TVL. If available they will be in our clearance section.
