DDPAI have an ingenious way to turning on/off parking mode.
Got below from DDPAI section in this forum:
The parking monitor function of DDPai mini3 based on "voltage detection":
1), When car engine is on, the camera will start to record normally based on 30FPS;
2), When car engine is off, the hardwire will detect the voltage change and then the camera changes to parking mode 1FPS time lapse recording immediately;
3), When car battery voltage lower than 12.4V or 12V or 11.8V ( optional in APP setting ), then the hardwire will cut off power automatically;
4), In addition, the defaulted maximum time of parking monitor is 24 hours, i.e. no matter if the voltage of car battery lower than the set voltage or not, the hardwire kit will cut off power automatically after 24 hours;
I believe it is possible to implement something like this with programming the firmware.
