ELSNU Backup Radar System Car Auto Vehicle Reverse with 8 Parking Sensors kit Distance Detection LCD Distance Display Sound Warning …

  • Note: Customer feedback has 2 sensors not working! Because when reversing (when the yellow line has voltage), the middle obstacle in front of the car does not affect the reversing. Therefore, the two sensors in the middle are not activated, and more resources of the control box are used on other sensors to make the data faster and more accurate! They are activated when the car moves forward!.
  • 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: Probe behind the car to prevent collision, probe in front of the car to prevent rubbing..
  • 3: On the display, there are 8 light bars representing each sensor, allowing the driver to distinguish the orientation of obstacles..
  • 4: The product has three alarm sound modes, real voice/beep/mute, which can be switched between each other..
  • 5: The product has 7-speed volume adjustable..
  • 6: The product alerts the driver through sound, numbers, and light bars at the same time..
