Is it necessary to install a reverse radar when you already have a reverse camera?

It is necessary to install a reverse radar even if you have a reverse camera. The reverse camera can only display images within a fixed range, while the reverse radar can monitor a larger area, enhancing safety during reversing by providing audio alerts when obstacles are detected. The working principle of the reverse camera is as follows: a wide-angle infrared camera is installed at the rear of the vehicle, and the display inside the car shows a clear view of the rear. The working principle of the reverse radar is: under the control of the controller, the sensor emits ultrasonic signals. When encountering an obstacle, an echo signal is generated. After receiving the echo signal, the sensor processes the data through the controller to determine the position of the obstacle. The distance is then displayed on the screen, and a warning signal is issued to achieve safe parking.
The rearview camera is indeed very helpful for seeing what's behind, but I believe installing radar is also essential. Because the camera requires you to constantly watch the screen, and if you get distracted by a phone call or conversation, you might miss important details. The radar's audible alerts constantly remind you of the distance, especially reliable during nights with poor lighting or rainy days when the image is blurry. The radar can also detect blind spots that the camera can't see, like low bushes or children running by. Last time in the parking lot, my camera showed a clear view, but the radar warned me of a nearby wall, preventing a minor accident. Installing radar is simple—just spend a little money to have it done at a shop, no hassle. Having an extra layer of safety is always better than dealing with repairs afterward. With one more warning tool, driving becomes easier, and risks are significantly reduced.
