Do you still need a radar if your car has a reverse camera?

[DelMatteo]

A car with a reverse camera still needs a radar. The reverse camera can only display images within a fixed range, while the reverse radar can monitor a larger area. When reversing the vehicle, it can enhance the safety of the reversing process. Additionally, the reverse radar will emit an audible alert when encountering obstacles. The reverse radar, also known as an anti-collision radar, serves as the most basic parking assistance system. It emits ultrasonic waves through ultrasonic sensors, which reflect back after hitting obstacles and are received again by the ultrasonic sensors. The controller calculates the distance between the vehicle and the obstacle based on the time taken for the ultrasonic waves to be emitted and reflected back, and alerts the driver with a rapid alarm sound through the warning device.
