G-Sensor Dash Cams: Impact Detection Explained

It detects sudden changes in acceleration and tells the camera to mark or protect the current clip. The exact trigger threshold and protected duration are model-specific.

Start with the manufacturer's default. Lower sensitivity if rough roads create frequent locked clips; raise it only if meaningful impacts are not being detected.

It can when the camera has power and a supported parking mode. Some systems wake after an impact, while others buffer or record continuously at a reduced rate.

Protected clips are usually separated from normal loop files, but the protected area can fill or be managed differently. Back up important footage as soon as possible.
