Product Description

Product Description

Universal Buzzer-Type Ultrasonic Parking Sensor System

The Buzzer Parking Sensor System is a safety assistance device designed to aid in parking and reversing maneuvers. It comprises three core components: high-precision ultrasonic sensors, an intelligent controller, and an audible buzzer.

The system works by utilizing the ultrasonic sensors to continuously scan for obstacles around the vehicle and relaying the data to the controller. The controller then activates the buzzer to emit tiered audible alerts, with the beep frequency increasing automatically as the distance to the obstacle decreases. Designed to help drivers mitigate blind spots, this device effectively addresses collision avoidance challenges during reversing, starting, or operating in low-visibility conditions, thereby significantly enhancing parking safety.

Application Scenarios

1.All-Round Parking Assistance
Provides real-time alerts for obstacles when parking in tight spaces.

2.Narrow Road Maneuvering
Helps maintain safe clearance from vehicles and walls in confined areas.

3.Traffic Congestion Safety
Detects distance to the vehicle ahead to prevent low-speed collisions.

4.Low Obstacle Detection
Detects curbs, posts, and other low-lying hazards around the vehicle.

5.Poor Visibility Support
Continuously scans surroundings in rain, fog, or darkness.

6.New Driver Guidance
Builds spatial awareness and confidence during parking and slow drives.

Key Features

Core Functions

1.High-Frequency Ultrasonic Precision Detection
Utilizes high-frequency ultrasonic sensing technology for accurate distance measurement. The sensors reliably detect obstacles within a 0.3-2 meter range behind the vehicle.

2. Comprehensive Blind Spot Coverage
Effectively scans for low-lying and commonly overlooked obstacles (e.g., road studs, pets, children), significantly reducing blind spots and enhancing safety in complex environments.

3. Intelligent Activation with Front and Rear Coordination
Braking: The front sensors activate automatically to detect obstacles ahead in real time.
Reversing: The rear sensors and front corner sensors activate automatically, providing comprehensive obstacle warnings.

4. Intelligent Tiered Audible Alarm
The alert beep frequency automatically increases as the distance to an obstacle decreases, providing an intuitive "slower for farther, faster for closer" warning system for precise risk assessment.

5.With Switch – Adjustable Volume at Your Convenience
The buzzer is equipped with a physical switch, allowing one-touch toggling between three modes: mute, low volume, and high volume, making operation simple and convenient.

6. Universal Easy-Install Design
Designed for universal vehicle compatibility, the system supports a wide range of models and offers a straightforward installation process without complex vehicle modifications.

Our Advantages

Product Advantages

1.IP67 Industrial-Grade Waterproofing
The sensors feature excellent sealing and waterproof performance, ensuring stable operation and reduced false alarms in heavy rain, car washes, or water-logged conditions.

2.Compact & Unobtrusive
The buzzer features a compact design and can be flexibly installed on the dashboard or other suitable locations without obstructing the driver's view. The wiring can be neatly routed along the edge of the windshield, keeping the interior tidy and aesthetically pleasing.

3.Real-Time Alert with Frequency-Based Warning
When an obstacle is detected, the buzzer emits warning sounds that progress from low to high frequency and from intermittent to continuous, with the rhythm adjusting according to the distance, providing intuitive danger alerts.

4.Flexible Configuration for All Scenarios
Multiple control unit options are available, including adjustable sensitivity and cost-effective versions. A variety of sensor types and waterproof cable options accommodate different vehicle models, budgets, and installation preferences.

5.OEM Color Matching 
Available in hundreds of OEM paint colors to perfectly match the vehicle's bumper. 

6.Non-Destructive Installation

A dedicated hole saw is included to ensure clean installation without damaging the original paintwork.
