Is a Reversing Radar Still Needed with a Reversing Camera?

Having a reversing camera still necessitates a reversing radar. While the reversing camera provides drivers with an intuitive real-time view of the area behind the vehicle, it cannot accurately reflect the precise distance between obstacles and the vehicle. On the contrary, due to the distortion in the camera's imaging, it might even affect the driver's judgment of distances. In such cases, the precise feedback on obstacle distances from the reversing radar becomes particularly important. The reversing radar, also known as anti-collision radar detection, utilizes ultrasonic principles. It sends out ultrasonic waves from sensors installed on the rear bumper, which reflect off obstacles. The system then calculates the actual distance between the vehicle and the obstacles and alerts the driver, making parking or reversing easier and safer. Only when the reversing radar and reversing camera are combined and closely integrated can they provide drivers with more comprehensive safety precautions.
As a seasoned driver with years of experience, I find the rearview camera to be a great tool. It provides a real-time view of the rear, especially for large objects, but its drawbacks are obvious: blurry images on rainy days, limited camera angles, and potential misses like low curbs or children's toys. On the other hand, the parking sensor uses sound to warn of obstacles in blind spots with precise distance detection. Combining both is perfect. For instance, when backing up in a parking lot, the camera shows an empty spot while the sensor beeps to alert me of a pillar, preventing many minor accidents. Car safety is no trivial matter, and I recommend not skimping on this investment. Installing both a camera and sensors makes driving much more reassuring.
In daily driving, the rearview camera helps me quickly position myself with clear and intuitive images. But the radar's alarm sound is crucial. Once, while reversing in a narrow alley, the camera didn't detect a bicycle under a low wall, but the radar beeped, successfully avoiding a collision. I think this combination is super practical for daily parking: the camera provides visual assistance, while the radar compensates for blind spots in crowded cities or tight parking spaces. After all, no one wants to scratch their car or injure someone. Although some cars come with cameras, adding a radar is inexpensive, and DIY installation isn't costly either. Safety first is truly cost-effective.
