Questions before you buy
How does a dash cam motion sensor work?
While the car is parked, the camera monitors changes in the image and saves a clip when movement meets its trigger rules. Operation and power requirements vary by model.
Is motion sensing the same as impact detection?
No. Motion sensing reacts to visual movement; impact detection uses a G-sensor to recognise force. A parking camera may support either or both.
Does motion sensor parking mode need hardwiring?
Often yes, because the camera needs power after the ignition is off. Check the exact model and use its compatible power accessory with battery protection.
Will passing cars trigger a motion sensor car camera?
They can. Sensitivity, viewing angle and traffic in the frame affect how often recording starts, which can increase storage use and power draw.
