Dash cams often come equipped with features that automatically protect crucial footage. One such feature is the G-sensor, which detects sudden movements or impacts such as in a car accident. Once an impact is detected, the Emergency File Lock function is triggered, preserving the current footage from being overwritten by subsequent recordings, even when in loop recording mode. This combination ensures that critical evidence from any incident is safely stored and available when needed.

In the realm of incident recording and preservation, MASIGO dash cam models - A330, A330D, and A340D, excel by providing this Emergency File Lock function. This valuable feature boosts reliability and automation, serving their users effectively during critical moments.
