I’ve had my dashcam plugged by cigarette before. The car shuts that off in 25 minutes or so. I’ve since moved to a battery pack set up - charged by cig socket and manually shut off if I am parked at home.

On my wife’s X3 I hardwired the dashcam, tapped alarm circuit for constant, cig socket circuit for switched. Dashcam switches to parking mode (lower draw) when the cig socket cuts out and has a low voltage cut off.
