There is a BMW ACE 3 dashcam (made by Thinkware) with radar based parking mode that works without this issue. The parking mode depends on battery charge level, it can last 24-36 hours on a good charge. It also has buffer video, so is able to record video prior to the trigger event.

I have to check that brand. I heard of thinkware but never heard of that.
Has anyone managed to get external USB battery powered parking mode? Basically I thought about keeping a battery charging bank plugged into USB, and that bank will keep powering the dash cam. If the car stops, dash cam can keep getting power from battery bank, if it needs to record in parking mode. Since parking mode only needs a little draw for detection, I thought something like 15000mAh batter should last every night, when car starts next day again it can charge battery and cycle continues. Is this possible?
