What is the wiring method for a car recorder?
3 Answers
The wiring method for a car recorder is: 1. Ground wire - connect to the car's ground wire, which needs to be installed in a safe and concealed location; 2. Constant power wire - connect to the car battery or constant positive terminal; 3. ACC positive wire - connect to the car's ACC power positive terminal. The functions of a car recorder are: 1. To protect the legitimate rights and interests of drivers; 2. To reduce accident rates and hit-and-run incidents; 3. Can be used as parking surveillance. The installation method for a car recorder is: 1. Install the glass bracket and car recorder, and secure the recorder body; 2. Clean the windshield with a car towel and install at an appropriate angle; 3. Insert the car recorder's power plug into the car cigarette lighter; 4. Connect the car recorder's power cord.
I've gained quite some experience from installing the dash cam myself last time. Generally, there are three wiring methods: The simplest is directly plugging into the cigarette lighter socket, which auto-starts when powered on, and you can just run the wires loosely – but it looks messy. I'd recommend connecting to the fuse box instead. Get a step-down cable kit, locate the ACC pin (the one that powers up only when the ignition is on), connect it to a fuse tap, and ground the negative wire to the car body. First, disconnect the negative battery terminal to prevent short circuits. Basic tools like a screwdriver and wire strippers will do. Hide the wires along the roof edge and A-pillar weather stripping – it takes about half an hour. Be sure to test that the voltage doesn’t exceed 12V to avoid frying the device. For long-term parking surveillance, you can connect directly to the battery but add a low-voltage cutoff to prevent draining it. The whole process isn’t hard – just consult your vehicle manual to confirm locations, prioritize safety, and you’ll end up with a clean, reliable setup.
Safety is no joke when it comes to wiring! I’ve learned the hard way—wrong connections caused a short circuit and smoke, nearly leading to disaster. Always disconnect the battery before starting, and use a reliable grounding point on the vehicle’s metal frame. Use a professional fuse tap for the positive terminal connection to the fuse box; don’t cut corners with makeshift setups, as overcurrent can easily cause a fire. Ensure the negative terminal is securely fastened. If the cigarette lighter is convenient, plug directly in but make sure the adapter matches—avoid cheap converters that overheat and cause accidents. When hiding wires, don’t force them into trim gaps; gently pry to avoid scratching paint or pinching wires. Also, check the battery’s condition, especially for parking surveillance, to prevent deep discharge. Professional installation is more reliable—after all, it affects both the vehicle’s lifespan and the dash cam’s performance.
