Parking sensor security system is a Car Reverse Radar Sensor System helps to prevent the risk factor of blind spot behind the car. The distance between car and obstacle is understood by the group of LED’s (D5 to D7). If the distance between car and obstacle is 25cm then D7 will glow. At the distance of 20cm D7 and D6 LEDs turn ON and at a distance of 5cm all LED’s (D5, D6, D7) glow. When the distance is more than 25cm then all LED’s will turn off


  1. Provide 8 sensitive ultrasonic sensors(Front:4 sensors, Rear:4 sensors) ensures your traffic security omnibearingly, providing increased safety for passengers, pedestrians and family members who happen to be around the moving vehicle.
  2. Real people voice with English speech alerts you section by section according different distance, closer the distance is, the alarm sound is shorter and rapider.
  3. Accuracy of obstacle distance can reach to centimeter.
  4. Self-inspection system can automatically check abnormal condition itself, avoiding reversing collision due to damaged sensors.
  5. The sensor color is same as the car, like the original part.
  6. Wide compatibility for cars, vans, trucks and so on.
  7. Subsection color display, from far to near.
    Colors in swatches are all available, please contact us to choose the color you want before overbooking.
