Questions before you buy
How does motion detection work on a dash cam?
The camera analyses changes in its image and saves a clip when movement meets its detection rules. Exact trigger timing and clip length depend on the model.
Will motion detection work when the car is off?
Only if parking mode remains powered through a supported hardwire kit, battery pack or always-on outlet. Standard switched outlets turn off with the vehicle.
Is motion detection the same as impact detection?
No. Motion detection responds to visible movement; impact detection uses a G-sensor to react to a bump or collision.
Can motion detection drain the car battery?
Any parking camera draws power. Use manufacturer-supported low-voltage protection or a compatible dash-cam battery pack and follow installation guidance.
