Our CAM222 twin lens reversing camera is effectively two cameras in the same body. This cable has been developed to send the signal from both cameras down a single cable. It overcomes issues of cross channel interference found with poorer quality cables. By having one cable it simplifies feeding cables through a vehicle. It also keeps the number of connections down to improve reliability. We now supply this cable with all our twin lens systems. This listing is for the 20m version. If you need longer we have them available in multiples of 5 metres.
