What does ACC mean in a dash cam?
2 Answers
ACC in a dash cam refers to a wiring method for power supply. Here are the relevant details: 1. Providing evidence: A dash cam is an instrument that records images, sounds, and related information during vehicle operation. After installing a dash cam, it can record the entire driving process in video and audio, providing evidence for traffic accidents. 2. Playback: The recorded footage can be played back, allowing traffic police to handle accidents quickly and accurately. This not only enables rapid clearance of the scene to restore traffic flow but also preserves valid evidence of the incident, contributing to a safe and smooth traffic environment. In court proceedings for road traffic accident cases, it allows for more precise sentencing and compensation decisions with solid evidence, and also provides proof for insurance company claims.
When it comes to the ACC on a dash cam, it stands for "Accessory" in the car's power mode. Simply put, it means when your car key is turned to the middle position of the ignition switch—the engine isn't started, but in-car electronics like the cigarette lighter and radio still work. I've seen many drivers choose the ACC mode when installing dash cams because it ensures the device only powers on and records while driving, avoiding battery drain after the engine is turned off. From my experience, connecting the ACC wire requires ensuring the circuit is reliable; otherwise, a sudden current surge during unlocking might burn out the dash cam or fuse. I recommend confirming ACC compatibility when purchasing a dash cam and opting for a hardwired installation instead of relying solely on the cigarette lighter socket to reduce power failure risks. Make it a habit to check if the dash cam automatically powers on in ACC mode before driving—it adds an extra layer of safety.
