Questions before you buy
How does motion detection work on a dash cam?
The camera monitors changes in its view and saves or begins footage when its detection conditions are met. Exact behavior varies by model.
Will a motion sensor dash cam drain the car battery?
Parking recording consumes power. Use the manufacturer-approved supply and low-voltage protection, and follow the vehicle maker’s guidance.
Does motion detection record before movement starts?
Only a buffered parking mode can preserve footage from before the trigger. Check how much context the specific camera retains.
Can motion detection replace impact detection?
No. They respond to different triggers, and neither ensures every incident is recorded. Some cameras combine both modes.
