Using parking mode will drain the 12v battery. Apart from maybe plugging a battery charger one night per week to keep it topped up, the inly other option is to run the dashcams from a seperate powerbank and charge that up when requited. Parking mode wiuld be good, but its a power drain you could do without. Or just dont switch on parking mode? Realistically do you live in an area where you need that to happen? I dont care, its not my car….lol.
Thats true but if somebody bumps into your car and drives off you will have to pay the excess and it will go as a claim against you.
That’s a primary reason I took the dealer fit front and rear dash cam for my new car.
