After-market Rear-View Camera Systems (also called reverse or back-up cameras) are designed to allow users to see on an in-cab monitor what's behind the vehicle and/or trailing implement. This allows him/her to more easily hitch, check on the work being performed-and they can help prevent equipment- and people-related accidents. Complete system kits usually include (1) a 5- to 7-inch color monitor (can connect up to three cameras and switch between views via button or remote); (2) a monitor harness and mount (dashboard-magnet or windshield suction cup); (3) camera convertors and connectors; (4) ample length of cable if a battery-powered system or appropriate app if a wireless system; and (5) one camera (with the option to purchase additional ones if the monitor has multi-screen capacity). Depending on make/model, camera may be night-vision with built-in infra-red LEDs to allow visibility in low-light conditions.
