What is the power cord connection method for a car dash cam?
2 Answers
The power cord connection method for a car dash cam is: 1. The positive wire is usually red and connected to ACC, the negative wire is usually black and grounded, the long wire is usually yellow and connected to the car's battery or the positive terminal of the constant power supply; 2. Locate the car's ACC, the position of ACC varies for each car, generally found on the left side at the bottom of the steering wheel, install and fix the dash cam, and route the power cable through the A-pillar to reach near the ACC; 3. Open the ACC cover, inside there are usually several small or medium-sized terminals, choose the terminal to connect; 4. Connect the red wire of the power cable to ACC and the black wire to the negative terminal. The working principle of a car dash cam is to digitally record and cyclically update the road conditions in front of or around the car, and even data such as in-car audio, the car's acceleration, steering, and braking are also recorded.
The most common method to power a dash cam is by plugging it into the cigarette lighter socket, which is both safe and simple. Just connect one end of the power cable to the dash cam's power port and insert the other end into the car's cigarette lighter socket—ideal for beginners. If the cigarette lighter is inconveniently located, you can route the cable to the fuse box, though this requires some skill, such as using a voltage reducer to prevent overload or seeking professional installation help. Be sure to avoid wrapping the cable around the steering wheel or pedals to prevent interference with driving. Choose a cable of moderate length to avoid clutter. For parking surveillance, the cigarette lighter may not be suitable as it cuts power when the car is off. In this case, wiring to the fuse box provides continuous power, but be cautious of battery drain. Beginners are advised to start with the cigarette lighter to gain experience before moving on to more advanced setups.
