Vehicles, especially trucks, vans, and large SUVs have blind spots where vision is restricted while reversing, this increases the risk of driving over something, or hitting a person or other parked vehicle. Parking sensors and reversing cameras can both help make parking safer by alerting the driver to a nearby object or increasing visibility behind the vehicle.
This discreet camera is perfect for your car or 4WD. With a generous wide-angle (120˚) field of vision for reversing, the camera boosts your safety and lets you view the road behind your car without relying on mirrors. The camera’s flexible, adjustable flush mount is easy to attach and set up, and its unobtrusive design won’t spoil the look of your car.
Whenever the driver uses reverse gear, then parking sensors get triggered automatically and transmits ultrasonic signals. When these signals strike the near object, immediately they get replicated and again they are captured by the parking sensors. Depending upon the elapsed time among sending & recapturing of signals, engine control unit measures the distance from the vehicle to an object.
When the car moves toward an object, then the alarm system gives an alert to the car driver with an audible sound to prevent the vehicle. Some of the automobile companies are providing an inbuilt camera to get an accurate vision of the surrounding area of the vehicle.
