This monitor is a popular mid range iten with the same performance as more expensive monitors. It shows a nice bright colour picture taking full advantage of the 800 x 480 pixel resolution. The camera uses a 700 TVL CCD sensor made by Sony. They use a high quality support board and we have these made with a stainless steeel bracket. Although the camera has sound the monitor lacks a speaker so is unable to give sound. The monitor can take 2 cameras and can be set up to automatically show channel 2 when you go into reverse. The CCD camera is capable of showing a colour day view and a black and white picture at night.
