4 Sensor Reversing Radar System with Host Buzzer Obstacle Detection Car Parking Aid for Toyota Corolla
This 4-sensor reversing radar parking aid system is designed specifically for Toyota Corolla vehicles. Equipped with four ultrasonic sensors installed on the rear bumper, the main control host processes obstacle distance data and drives the buzzer to send out different frequency beep reminders. As obstacles get closer, the beep warning becomes more frequent, assisting drivers to judge rear-side barriers without visual observation. All sensors meet vehicle-grade waterproof standards, maintaining stable performance under rain splash and dust conditions. Supplied with complete accessories, this system provides a practical and cost-effective aftermarket parking safety upgrade solution for Toyota Corolla sedan owners and auto repair shops.

4-sensor layout provides multi-direction obstacle detection for Toyota Corolla rear bumper area
Built-in host buzzer outputs variable beep alerts according to real-time obstacle distance
Accurate short-range detection helps drivers avoid scratches and collisions during reversing and parking
Complete kit includes sensors, main control host, buzzer and full wiring harness
Simple aftermarket wiring installation, perfect for Toyota Corolla safety refitting projects

System Highlights
Four-Point Multi-Area Obstacle Detection
Four ultrasonic sensors arranged on the rear bumper cover a wider rear detection zone, effectively capturing obstacles, walls, and pedestrians behind Toyota Corolla vehicles while reducing blind-zone missing-detection risk during reversing.
Host-Driven Buzzer Distance Warning
The main control host analyzes distance signals from sensors, with the buzzer changing beep frequency according to obstacle proximity. Continuous long beeps trigger when obstacles enter dangerous distances, providing clear audio prompts for drivers.
Vehicle-Grade Waterproof & Dustproof Sensors
Sensor units feature sealed housing structure with IP67 waterproof rating, resisting rain splashing, mud, and dust erosion while maintaining stable detection performance under complex daily driving weather conditions.
Full Set Accessory for Aftermarket Refitting
The complete kit contains 4 sensors, control host, buzzer and matched wiring harness. No additional parts need to be purchased separately, making it suitable for aftermarket modification of Toyota Corolla 12V sedans.
Cost-Effective Parking Safety Upgrade
Pure buzzer audio alert design eliminates the need for extra display monitors, reducing overall cost while providing core reversing obstacle warning functionality. Ideal for individual car upgrades and auto parts wholesale orders.
