4 Sensor Parking Radar Alert System Waterproof LED Display Buzzer

Four sensors are evenly mounted on the rear bumper to form a complete rear detection zone, covering most blind areas behind the vehicle and capturing obstacles in the reversing path.

Ultrasonic detection works independently of light conditions. It maintains stable sensing performance at night, in underground parking lots and dim alleyways without auxiliary lighting.

Each sensor probe adopts a sealed IP67 waterproof structure. It withstands rain, car washing and muddy road splashes, and keeps consistent detection accuracy in complex outdoor environments.

The system wakes up automatically once reverse gear is engaged. It updates distance data on the LED display in real time and adjusts buzzer alarm frequency according to obstacle proximity.

This parking radar kit is mainly designed for passenger cars and light vans. It provides intuitive dual visual and sound warnings for daily urban parking and reversing scenarios.
