Caporegime
I think the Blackvue does and will run until it detects your car battery is low. The problem with most dashcam is that most don't have a large capacity battery or just a capacitor so it does not hold enough juice to run it for long. The cheat way is get something like a the Gitup and change the settings to run it in Dashcam mode with it continuous record AFTER the power has shut off. But I think there is a time limit to like either 30 or 60mins.
