Rear Bumper Car Reverse Sensor Kit Parking Assistance System Reversing Parking Sensor in 4 X 30mm Sensors

This system focuses on rear area detection with four evenly distributed 30mm sensors installed on the rear bumper. The four-point layout covers the main rear reversing zone, effectively capturing obstacles on the left, middle and right rear side. It reduces common rear blind spots and helps drivers judge the rear space clearly when backing up.

Not applicable for radar detection. The system relies on high-sensitive radar probe technology. It maintains stable detection performance regardless of light conditions, working reliably at night, in dim underground parking lots and shaded environments without being affected by darkness.

Each 30mm parking sensor adopts a sealed waterproof structure with IP67 waterproof grade. It can block rain splash, road dust and mud splashes. The internal sensing components are well protected, so the sensors keep accurate detection even on rainy or dusty roads.

The system automatically activates when shifting into reverse gear. It continuously measures the distance between the car and obstacles, and changes the buzzer alarm frequency intelligently. The warning tone becomes faster as obstacles get closer, delivering intuitive danger reminders without extra manual operation.

This 30mm rear bumper parking sensor kit is designed for 12V passenger cars including sedans, SUVs and hatchbacks. It is not adapted for 24V heavy trucks, buses and other large commercial vehicles. It is a cost-effective parking safety accessory for family vehicles and auto modification shops.
