Hello.
I have purchased a BlackVue dashcam (front and rear cameras) that come with what the vendor calls Power Magic Pro. A device that is connected to car's power system, while the dashcams itself are connected to it. Power Magic monitors car battery's voltage and once it drops below the set minimum, shuts down the dashcam parked mode recording. Otherwise the dashcam is recording constantly even when the car is off.
I will take my G30 to an official BMW dealer to install the dashcam, but I am sure they've never installed a dashcam through things like Power Magic controller.
I will have to tell them which voltage should be set on Power Magic as a trigger to shut off camera.
Could anyone advise on a correct voltage value, below which it is wise to have cam stop draining the power? I want to be sure I can always start the car when I get into it
Thank you very much in advance.
P.S. Available cut-off voltages are:
23.3V
22.8V
12.5V
12V
