Is it necessary to install both a reversing camera and reversing radar?

[Daryl]

If conditions permit, both can be installed. If not, either one can be chosen based on the situation. Here is an introduction to reversing radar: Principle of reversing radar: The reversing radar emits ultrasonic waves through ultrasonic sensors. When the ultrasonic waves hit an obstacle and reflect back, they are received by the ultrasonic sensors. The controller then calculates the distance to the obstacle based on the time taken for the ultrasonic waves to be emitted and returned. Finally, the buzzer emits a rapid alarm sound to alert the driver. Main functions of reversing radar: Accurately measure the distance between the rear of the vehicle and the nearest obstacle; emit a rapid warning sound when reversing to the limit distance to remind the driver to brake; repeatedly emit a voice warning sound to alert pedestrians.
