This matches the dual lens brake light camera with our MON705 dash monitor. The dual lens camera is designed to show a constant view when travelling forward and will switch to the downward facing camera when you go into reverse. Both lenses use a high quality 700 TVL CMOS sensor to give a good colour picture during the day and a black and white one at night. The night view for the reversing camera is aided by IR LEDs on the camera. The rear facing camera will depend on street lighting for a image.
