You need a hardwire kit to connect to the fuse box of your vehicle.

Because our dash cam does not contain a built-in battery, it only has a super capacitor and 1mAh Lithium Metal (only used to save time). Due to the long transportation process, the battery may run out and cannot be turned on.

When you encounter this situation, you just need to keep the power on, and wait a minute, it should be turned on and work normally.

If that does't work, please contact us and we will provide free replacement and lifetime technical support.
