What do the three colors in the reversing camera represent in terms of distance?

Green indicates a distance of 1 to 3 meters, yellow represents a distance of less than 1 meter, approximately between 60 to 100 centimeters, and when approaching red, the distance is reduced to 60 centimeters. Below is relevant information about the reversing camera: 1. Introduction to the reversing camera: The reversing camera, also known as a parking assist system, or vehicle backup monitoring system, is referred to in English as: vehicle-backup-camera. This system is widely used in various large, medium, and small vehicles for reversing or driving safety assistance. 2. Advantages of the reversing camera: Installation is simple; generally, a standard single-output reversing camera only requires connecting the positive power wire to the positive terminal of the vehicle's reversing light power and the negative power wire to the negative terminal of the reversing light or to ground (GND). Wiring can be easily understood with a simple study based on the vehicle model, and the camera can be installed by drilling a hole in an easily accessible position.

When I first learned to drive and bought a car with a rearview camera system, it took me a while to understand those colors. Green represents the safest distance, usually over 1.5 meters, meaning you're still far from obstacles and can reverse with confidence. Yellow is the warning zone, roughly between 0.5 to 1.5 meters, like saying 'Hey, be careful,' reminding you to slow down and not be reckless. Red is the danger zone, less than 0.5 meters, almost hitting something, with beeps going off nonstop, telling you to brake immediately. Once, while parking in my neighborhood, I was so focused on the green that I didn’t notice the red and almost scraped my neighbor’s car. Now when I use it, I always glance at the rearview mirror too, especially at night or in the rain when the camera can get blurry and misjudge distances. Overall, this feature is super practical, but don’t rely on it too much; regularly cleaning the camera and familiarizing yourself with your car’s manual distance values are key to ensuring safety.

I'm quite interested in the reverse camera system because it combines camera and sensor technologies. The three colors intuitively indicate distance: green represents the far range, typically beyond 1.5 meters, suitable for normal operation; yellow warns of medium distance, approximately 0.5 to 1.5 meters, indicating cautious maneuvering; red is the most urgent, within 0.3 meters, equivalent to an emergency signal requiring immediate stopping. Parameters may vary significantly across different vehicle models, and in my car, the default settings are calculated through ultrasonic detection. During use, I've also noticed that poor weather or lens obstruction can cause mislabeling, so I make it a habit to test the camera angle before reversing to ensure system accuracy. This not only avoids friction but also extends the equipment's lifespan.

As a long-time driver, I deeply understand the importance of the colors in a rearview camera. Red indicates extreme proximity, typically 0-30 cm, requiring immediate braking to prevent a collision; yellow is a warning distance, 30-150 cm, reminding you to slow down and stay alert; green indicates a safe zone, over 150 cm, allowing continued movement. These colors are based on sensor settings and can effectively reduce accidents, but drivers need hands-on experience to familiarize themselves with their vehicle's distance settings. More importantly, don't rely solely on the camera—develop the habit of turning your head to observe and slowing down when reversing, especially in foggy or dusty conditions where reliability may decrease. The principle of safety first always takes priority.
