Product Description

Product Description

Struggling with parking?

1.Difficulty judging parking distance
2.Narrow roads make it difficult to maintain a safe distance, increasing the risk of scratches
3.Rear blind spots during reversing
4.Limited side visibility increases the risk of collisions
5.Front blind spots and short following distance may lead to rear-end collisions
6.Low-profile obstacles are difficult to detect
7.Reduced visibility in rainy or nighttime conditions
8.New drivers often struggle to accurately judge parking distance

Product Overview

The buzzer parking sensor system is an essential safety assistance device for vehicles during parking and reversing. Comprising ultrasonic sensors (probes), a control unit, and a buzzer, it accurately detects obstacles around the vehicle and delivers clear audible alerts, eliminating the need for constant visual checks. By helping drivers overcome blind spots and limited visibility, the system significantly enhances parking convenience and overall driving safety.

Working Principle

When reverse gear is engaged, the parking sensor system activates automatically. Ultrasonic sensors detect surrounding obstacles and calculate distance via the control unit. As the vehicle approaches an obstacle, the buzzer alert changes from slow beeps to rapid beeps, and finally a continuous tone at a critical distance, warning the driver to stop in time. Distance can be judged clearly through sound, making reversing safer and more convenient.

Key Features

1.Precision Ultrasonic Detection:
High-sensitivity sensors detect obstacles around the vehicle accurately, even in tight spaces.
2.External Audible Alerts:
A separate buzzer emits warning sounds that change frequency based on distance, giving you real-time feedback.
3.Easy Integration:
Compatible with most car models; the external buzzer can be mounted where convenient for maximum audibility.
4.Enhanced Driving Safety:
Helps reduce collision risks when parking, reversing, or starting the vehicle.
5.Durable & Weatherproof:
Sensors and buzzer are designed to withstand rain, dust, and varying temperatures.

Our Advantages

1.Multiple Sensor Options:
Available in various specifications and models, with customizable sensor colors to perfectly match your vehicle's exterior without affecting its appearance.
2.Flexible Configuration Choices:
Optional 2 / 4 / 6 / 8 sensor configurations to meet different parking and detection needs.
3.Upgradable Waterproof Design:
Supports upgraded waterproof cables and main control unit, ensuring reliable operation even in rain or harsh outdoor conditions.
4.Hidden Installation:
Compact and discreet sensors blend seamlessly into the bumper for a clean, factory-like appearance. The mini-sized external buzzer is easy to place anywhere inside the vehicle without taking up interior space.
5.Easy Installation:
Comes with a hole saw and detailed installation manual — no professional tools or complex wiring required. Most car owners can complete installation easily, saving both time and cost.
6.Superior Stability & Reliability:
Built with high-quality electronic components and advanced manufacturing technology, the system performs consistently in all weather conditions — rain, heat, or cold — for 24/7 protection.
7.Wide Vehicle Compatibility:
Universally compatible with a wide range of vehicles including cars, SUVs, MPVs, vans, and trucks.
