What is the definition of the 4 wires in a reverse camera?

DC power plug connects to the reverse light, generally only the red wire is connected, along with the red wire on the RCA plug, providing the signal for reverse video switching to the head unit. The RCA connector transmits the video signal from the camera to the head unit. Below are detailed introductions about reverse cameras: 1. Selection of reverse cameras: (1) For passenger cars, consider the camera model (optional waterproof and night vision features), screen size (3, 5, or 7 inches), and power supply voltage (12V). For large vehicles like trucks and buses, 24V is sufficient. (2) For large vehicles, selection should be more cautious. The operating conditions of large vehicles differ significantly from passenger cars. For example: harsh driving environments on construction sites, extreme temperatures, high frequency of reverse gear usage, and long working hours. Large vehicles typically use a 24V power supply, so reverse cameras designed for passenger cars cannot be used. Therefore, when selecting a product, ensure it is the right fit rather than being influenced by price or other factors. 2. Considerations: When choosing a reverse camera, ensure compatibility with your vehicle model by evaluating the camera model, power supply voltage, screen size, waterproofing, shock resistance, and anti-interference capabilities.
