Product Introduction
The Car Parking System alerts the driver to the distance of hidden obstacles while the vehicle is reversing. This package includes 4 sensors, a central controler, a display panel, and a buzzer. The display panel produces a visual warning and the buzzer produces an audible.

How it Works
• When reversing, the 4 rear sensors that are installed on back bumper send ultrasonic waves to detect obstacles behind vehicle. Then the controller receives the signal & transmits to the speaker and to LCD display.
• LCD screen will inform you the distance in feet to the obstacle
• The speaker emits long intermittent beeps at 4-6 feet, and as you move closer to the obstacle the beep increases in frequency. When you are 1 foot away from the obstacle, the sound is continuous
• LCD screen is 2 colors with indicators for which sensors (right or left) are detecting the obstacle. The LCD display is 3” by 1/2”
• Power is supplied by tapping into the reverse lights
