This Radar Dash Cam Catches Parking-Lot Hit-and-Runs

How a radar dash cam watches your car while parked

Most dash cams do their best work when you’re driving. The problem is, the stuff that ruins your week often happens when you’re not even there. Parking-lot hit-and-runs. Door dings with a “who, me?” shrug. A mirror swipe with no note.

That’s where a radar dash cam earns its keep. Instead of staying fully awake all night, it can sit in a low-power parking mode and “wake up” when motion enters a detection zone. You get video of the approach, not just the aftermath.
