This product does not support simultaneous recording of three cameras. It can only keep two cameras at the same time (three choices two), that is, the camera in front of the camera + the camera in the car at the same time, or the camera in front of the camera + the camera in the rear view.
If the rear view camera is installed at the same time, the selection screen is displayed as the front camera + in-vehicle camera mode. When the reverse gear is reversed, the screen will automatically display the rear view screen in full screen. If the reverse gear is canceled, the camera will be automatically restored to the front camera + car.
The internal camera mode, and when the reverse gear is reversed, does not affect the same recording inside and outside the vehicle.
