Why No Car, Truck Or Van Should Be Without A  Reverse Backing Alert Sensor System. If you've ever backed into another car while parking or an object that was unseen because it was below your line of sight, you know that even a small fender bender can be costly. If you're a business that operates trucks, delivery vans or cars, you may have significant annual losses due to these types of accidents

Sound Alert Protection When Backing Up
When the vehicle is reversing, 4 rear bumper sensors send out ultrasonic waves 4 times per second that detect obstacles behind the vehicle up to 8 feet away. The waterproof controller receives the signal and transmits to the wireless LCD display.

The wireless LCD display and speaker sounds long intermittent beeps when an obstacle(s) is up to 8ft. from the rear of the vehicle and shows in feet the distance to impact as well as on which side of the vehicle the obstacle is located. As the rear of the vehicle moves closer to the obstacle(s), the beep increases in frequency. Once that distance is 1ft., the alert becomes a continuous sound.

System Includes:
Waterproof controller, Wireless Premium LCD display with 8ft. power cable, four premium rear 22mm sensors with 9ft. cable that detect obstacles up to 8ft away, four 7 degree wedges, drill bit, scotch lock and owner's manual/installation instructions.
