Parktronic 8 Parking Sensors Kit Reverse Backup Radar System Rear and Front View with Sound Warning Ultrasonic Distance Detection for Car Vihicle

When the product is working, the sensor emits ultrasonic waves. When encountering an obstacle, the ultrasonic waves are reflected. The sensor receives the reflected signal and transmits it to the control box. Through calculation, the control box obtains the distance between the vehicle and the obstacle, and reminds the driver to pay attention through the display and sound, etc., to avoid danger. It is a good helper for us to drive the car! ^^ 1: When reversing, activate the rear 4 sensors and the front 2 sensors to detect and alarm. During normal driving, when braking, the 4 sensors in front of the car are activated to assist the driver to safely pass through narrow passages. When you release the brake, the parking sensor will work for about 15 seconds before stopping.
^^ 2: The product alerts the driver through sound, numbers, and light bars at the same time.
^^ 3: Probe behind the car to prevent collision, probe in front of the car to prevent rubbing.
^^ 4: On the display, there are 8 light bars representing each sensor, allowing the driver to distinguish the orientation of obstacles.
^^ 5: The product has three alarm sound modes, real voice/beep/mute, which can be switched between each other.
^^ 6: The product has 7-speed volume adjustable.
