Easy Installation in 8 MinsThe waterproof camera and HD monitor are powered by one power supply, No need to power the camera and monitor separately, just connect the monitor to a cigarette lighter adapter/Acc/fuse etc, then wire the camera and monitor. Plug and Play - Much less installation effort than wireless rear camera systems. Wired Back up Camera, Stable Signal TransmissionThe wired reversing camera kit has more stable transmission and will not lose signal at any time. If your wireless backup camera is always intermittent and delayed, a wired camera is a reliable companion for every drive. The rv backup camera connects directly to the monitor via a 66ft cable and is widely used on trailer, truck, tractor, bus, rv, van, suv and more.
