This 4 pin cable is for the CCD reversing camera systems that have waterproof connectors. It is 15m long and comes with a rubber O-ring on the screw fit connector. Together with the rubber boot that fits over the join it gives 2 layers of water ingress protection. The cable takes both the current and video signal. There are a number of designs of 4 pin connector that have been used for reversing cameras so please check carefully your existing system if this is a replacement.
We have these cables made to our specification. The cable diameter is 0.5mm with a pure copper and aluminium foil outer shielding. The inner cores are made from pure copper using 12 strands of 0.12mm bare copper. A lot of cable on the market use copper coated aluminium (CCA) or copper coated steel (CCS) which are more easily damaged and give reduced image quality.
