Do you still need a reversing radar if you have a reversing camera?

Even with a reversing camera, a reversing radar is still necessary. The reversing camera can only display images within a fixed range, while the reversing radar can monitor a larger area. When reversing the vehicle, it can enhance the safety of the reversing process. Additionally, the reversing radar emits an audible alert when encountering obstacles. Below is some relevant information about reversing radars: The reversing 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 upon hitting an obstacle and are received again by the ultrasonic sensors. The controller then calculates the distance between the vehicle and the obstacle based on the time taken for the ultrasonic waves to be emitted and reflected back. Finally, an urgent alarm sound is emitted by the alarm to alert the driver.
I believe that even with a rearview camera, adding a reverse parking sensor is essential as they complement each other and enhance safety. Having driven many cars, I've personally experienced situations where the camera image was blurry during rainy weather, making it impossible to see small children or objects behind the car. However, the radar's audible alerts about distance allowed me to react instantly and avoid danger. The camera only displays the rear view, which can be distorted due to poor lighting or camera issues, whereas the radar provides accurate detection in dark areas or blind spots. Data I've seen shows that most accidents occur due to camera lag or failure to cover close-range blind spots, which the radar effectively addresses. During daily reversing, the camera shows you the situation, while the radar's sound alerts prompt you to adjust speed proactively to avoid collisions. Especially for novice drivers, this serves as a double safety net. Installing a radar is not expensive—just a few hundred yuan, far less than the cost of accident repairs. During regular vehicle maintenance, check that both systems work in sync to ensure readiness for unexpected situations and to protect your family's safety. I think this investment is absolutely worthwhile; don't cut corners and overlook critical details.
