How far can a rearview camera see is considered normal?

Rearview cameras can see a distance of more than 3 meters. The following are the advantages and disadvantages of rearview cameras compared to parking sensors: Advantages of rearview cameras compared to parking sensors: Simple installation. Generally, a single-output rearview camera only requires connecting the positive power wire to the positive terminal of the car's reverse light power, and the negative power wire to the negative terminal of the reverse light or to the ground (GND). The wiring can be easily understood with a little research based on the car model, and the camera can be installed by drilling a hole in an easy-to-install position. It provides a clear view. Once the car is put into reverse gear, the real-time image of the rear of the car is clearly displayed, making it easier for the driver to judge. Disadvantages of rearview cameras compared to parking sensors: In terms of proactiveness, the rearview camera requires the driver to first observe the dynamic images on the display screen during reversing, meaning the situation can only be understood by looking. However, parking sensors can alert the driver with a sound when an obstacle is close to the right side of the car while the driver is observing the left side.
After driving many cars, I've found that the normal visible distance of a reversing camera generally ranges from 2 to 5 meters, varying by vehicle type. Due to their taller body height and slightly elevated camera position, SUVs may have a slightly longer range of about 4 meters, while sedans typically achieve 2 to 3 meters. The system is designed to help drivers clearly see obstacles like garage walls or parking bollards during low-speed reversing, allowing safe steering adjustments to avoid collisions. However, don’t rely solely on it—strong light, rain, or snow can blur the image, reducing visibility to just over 1 meter. That’s why I recommend glancing at the rearview mirror and side windows while reversing to ensure no small animals or low objects are missed. Regularly cleaning dust off the camera lens is also crucial, as a clear lens can maximize visibility up to 5 meters. In short, a clear view beyond 2 meters is considered normal, but if issues arise, promptly consult a mechanic to check wiring or the lens.
