Description WIRELESS PARKING SENSORBackup radar system adopts 2.4G wireless new technology which is different from other cabled car reverse system. The LED display and the host is wireless connected which gives you much operating convenience. 4 ULTRASONIC SENSORS4 sensors at the rear bumper of your vehicle alarming for safe reversing. Advanced chip set for precise detection and coverage. The sensors will buzz to alarm you in 3 modes according to the obstacles distances (0-2M). Connect the 4 sensors ABCD to corresponding ABCD socket. REVERSE RADAR PERFORMANCEThe reversing sensors have superior performance: anti-freeze, waterproof, quakeproof and durable. Beep sound will get louder and intenser for timely warning on detecting small children, little animals, passengers, pedestrians and other people around the moving vehicle and helps you to prevent collision accidents. EASY INSTALLATIONOur wireless car reverse system fits your car (12DCV voltage vehicle) with universal hole saw. Use our drill tools, you can easily drill holes on the bumper of cars and install the parking sensors. Do not need to connect the LED display and host on the benefits of its wireless connection function.
