> For the automatic shutdown I have used a 12V programmable timer in combination with an optocoupler.
> When the car is powered the the timer gets triggered and is starting the power supply for the Raspberry pi, Dashcam pi will get started and will do its job. When the car is turned off the optocoupler triggers the GPIO pin of the raspberry and starts a shutdown. After 15 seconds the timer is shutting down and the raspberry pi is powerless.

Thanks for the advice!
