What is the principle of the reverse camera trigger line?
2 Answers
It uses the radar waves emitted by the radar probes on the bumper to reflect and receive signals to measure the distance to obstacles. Below is relevant information about the reverse camera: 1. Definition: The reverse camera, also known as the parking assist system, reverse visual system, or onboard monitoring system, is widely used in various large, medium, and small vehicles for reversing or driving safety assistance. This system provides a more intuitive and clear view of the rear situation when reversing, making it one of the most practical configurations for reversing safety. 2. Technologies used: Professional onboard probes have further improved anti-magnetic, anti-vibration, waterproof, and dustproof performance. The onboard display uses TFT true color, with anti-magnetic treatment to eliminate signal interference and flicker. It can simultaneously receive two video signals, play VCDs and DVDs without a decoder, and features automatic horizontal switching and automatic on/off functions for the reverse visual system.
Last time I installed a rearview camera myself, the trigger wire is essentially just a wire connected to the reverse light. When you shift into reverse gear, the reverse light turns on, and the trigger wire detects this voltage change, sending a signal to the car display to activate the rear camera. This way, the screen automatically shows the rear view, eliminating the hassle of manually turning on the camera, which is especially useful in low-light conditions. During installation, it's crucial to correctly identify the reverse light wiring; otherwise, it might malfunction or interfere with other electrical components. The principle is quite straightforward—it makes reversing safer and more convenient, helping to avoid scratches or accidents. For someone like me who enjoys DIY modifications, it's a key little component that enhances the driving experience.
