i tried the stuff for some days now, see also: https://youtu.be/mDqC9cuPbqg
hardwire/powerbank DOES NOT WORK because of BUGS in the SW... 7.6, 7.7 and the pre-alpha-7.8 that roav support is mailing had the same bugs:
the parking monitor CAN NOT be disabled. the setting is ignored and its always on...
hardwired: the cam is recording hundred of clips here every night...the motion-detection (by picture) can NOT be disabled (bug). this is using much electricity... (car-battery should be killed in some days if full)
without hardwire: it should stop after 15 motion-detection-clips and record then only if g-sensor turns it on..
