High-sensitivity sensors and infrared filters ensure clear video recording in low-light conditions. In very low light, the night vision mode may automatically activate, resulting in black-and-white video, which is normal. This feature can be disabled in settings if preferred.

The built-in G-sensor detects sudden movements or collisions, automatically triggering emergency recording and locking the footage to prevent overwriting. The parking mode allows the dash cam to monitor surroundings when the car is parked.

The loop recording feature automatically overwrites the oldest unlocked video files when the memory card is full, ensuring continuous recording without manual intervention. Locked emergency recordings are protected from being overwritten.
