Motion Detector Dash Cams for Parking Protection

The camera compares successive frames and saves footage when the scene changes enough to cross its trigger threshold.

Only models with buffered parking mode retain pre-event footage. Check the manual because buffer behaviour varies.

Some powered outlets stay live, but most reliable parked setups need a compatible hardwire kit or external dash-cam battery.

Traffic, people, shadows, rain and reflections can change the image enough to trigger recording.

No. Impact detection responds to a shock measured by the G-sensor; motion detection responds to visual change.
