When engine is off, does the battery pack supply the power until it is discharged, then the vehicle 12V battery kicks in until the specified cut off voltage then shuts off or vice versa?

When the engine is on the 12v outlet is powering the camera and charging the battery. Battery reaches full charge in an hour (I always reach full charge during commute which is nice). A full charge lasts up to 72 hrs and I've been seeing about 48 hrs.
When the engine is off the dash cam battery pack supplies the dash cam until it is drained. Once drained that's it. Never pulls from the car battery because the 12v outlet loses power when engine is off. Now this is only one way to wire it. The battery also has the ability to be hard wired to the car battery which means it will pull from the car battery until the car battery reaches 12v then the dash cam battery will shut off to prevent draining the car battery.
