2 to 1 Auto Camera Switch System

How To Install It? Great set-up for caravans or trailers when you want an auto camera switch system to change your reverse camera when you have the caravan or trailer connected. When the Caravan or Trailer is connected it will show the camera on the caravan or trailer and when you unhitch it will go back and just show the car reverse camera. Two video input sources, one video output, for switching between two video sources.Solve the problem of two cameras into one display.When two video signals are available, the main input V1 (Caravan Camera) takes precedence and the secondary input V2 stands by. If the main signal V1 is not available, it will automatically switch to the secondary input V2(Car Reverse Camera).Power supply: DC 12V and DC 24V (optional).
