Guide Overview
Best Dash Cam with G-Sensor Emergency Lock
A dash cam with G-sensor detects sudden movement, impact, or collision and automatically locks important footage. This helps prevent accident clips from being overwritten by normal loop recording.
G-sensor emergency lock is one of the most important safety features in a dash cam because it protects key evidence when you may not be able to save the clip manually.
