The first time I know baidu even has it own wiki. Amazing Thanks. I will test in car.or maybe you can google "cutting off voltage of accumulator" . Here is a Chinese page for your reference.

and make sure the cutting off voltage is onload voltage not NO LOAD.
the accumulators in vehicle are 45Ah or 60Ah, calculate the output current for a dash camera is only 5*0.5(MAX)/12/80%(swithcing efficiency)=0.26A, so a regular 45Ah accumulator will power a dash camera for 173hours or 7 days in a parked car.
When you leave your vehicle in garage and go for a long vacation, please slide the toggle switch to OFF position, or take the positive pole away from accumulator.
