A:Answer This kit is designed to be attached to the vehicle fuse box, usually using fuse taps. One of the two power leads needs to be attached to an always on fuse/source and the other to a fuse/source that only has power when the ignition is on. This configuration is necessary if you wish to use the parking mode where it will record when an event is detected when the car is parked/ignition off. I don't have the instructions available right now, but I believe it can be set up without the parking mode option. Connecting to the battery would most likely require extending the wires and result in an always on camera. And, of course, if connecting directly to the battery, make sure you have adequate fusing just to be safe.
