How to install the driving recorder without damaging the battery

Nowadays, people's safety awareness is particularly high, and most car owners will choose to install driving recorders in their cars. If an accident occurs during driving, the driving recorder can be used as strong evidence. So how to install the driving recorder without damaging the battery?

When we install the driving recorder, we can get electricity through three ways: step-down cable, OBD or cigarette lighter, so as not to harm the battery of the car.

Step-down line power: Step-down line power is generally obtained by reading the positions of interior lights and fuse boxes. When the vehicle is turned off, it will automatically cut off the power supply without damaging the battery.

Power on OBD: It is necessary to check whether your vehicle will be powered off after the OBD is turned off, because many models will be powered off after turning off, and very few models will be powered on after turning off.

Power supply by cigarette lighter: If power is supplied by cigarette lighter, the driving recorder can only work normally when the vehicle is powered on. When the vehicle is turned off, the driving recorder will stop working, no longer consume electricity and will not damage the battery; The only drawback is that the cigarette lighter switch is generally under the center console, and it is complicated to wire for beauty.
