Guide Overview
Best Dash Cam with Emergency Recording and G-Sensor
A dash cam with emergency recording uses a G-sensor to detect sudden impacts, hard braking, or collisions. When an event is detected, the dash cam can lock the video clip so it is not overwritten by normal loop recording.
This feature is important for accident evidence because it helps protect the most important footage automatically, even if you cannot manually save it during the incident.

How emergency recording works
Emergency recording is usually triggered by a built-in G-sensor. When the dash cam senses impact or sudden movement, it saves the current video clip into a protected folder. This helps prevent important footage from being erased during loop recording.
