What is the distance indicated by the three lines in a reversing camera?
2 Answers
The auxiliary lines in a reversing camera consist of three colors, each representing a different distance. Red line: This is the warning line, indicating a distance of 30 cm from the rear of the vehicle. It is not advisable to continue reversing beyond this point. Yellow line: This is the deceleration line, indicating a distance of 60 cm from the rear of the vehicle. You can continue reversing but should slow down. Green line: This is the safety line, indicating a greater distance from the rear of the vehicle, allowing you to continue reversing safely. More details are as follows: 1. The distance settings for the three lines in a reversing camera may vary by manufacturer. After installation, you can measure them yourself. Reversing also requires practice; relying solely on the reversing camera cannot solve all practical problems. 2. Always check the situation behind the vehicle before reversing and plan your reversing path. When adjusting the direction of the front wheels, ensure they won’t hit any obstacles, and avoid accelerating while reversing. Additionally, note that the steering wheel should be turned in the same direction as the intended movement of the rear of the vehicle—turn right if the rear is moving right, and left if it’s moving left. Don’t focus only on the rear while reversing; periodically check the side mirrors to monitor the distance between the vehicle and any obstacles on either side.
In a rearview camera system, three reference lines are used to judge the distance behind. Among them, the green line usually indicates the safe zone, approximately beyond 1.5 meters. I often use it to estimate parking space, ensuring the car can safely reverse into the spot. The yellow line is the warning zone, about 1 meter away, reminding me to slow down and look carefully to avoid scraping walls or obstacles. The red line is the danger zone, within 0.5 meters or closer. Based on my own experience, when the red line touches an object, the car is almost touching it, and you must stop immediately. These distances may vary depending on the car manufacturer's settings. For example, the red line is more sensitive in the SUV I drive, so I recommend referring to the vehicle manual or adjusting the camera angle to suit personal habits. Regularly checking the cleanliness of the camera is crucial, as dirt can distort the lines and increase the risk of misjudgment. Remember, although these lines are very helpful, never neglect checking the rearview mirror or turning around to observe the actual environment—this can prevent accidents.
