- Manual Power: Press and hold the power button for a few seconds to manually turn the device on or off.
5.2 Recording Modes
- Loop Recording: The dash cam continuously records video in segments (e.g., 1, 3, or 5 minutes). When the SD card is full, the oldest unlocked footage will be overwritten by new recordings.
- Emergency Recording (G-Sensor): In the event of a sudden impact or collision, the built-in G-sensor will automatically detect the event and lock the current video segment, preventing it from being overwritten.
5.3 Menu Navigation

6.3 24-Hour Parking Monitor & Time-Lapse Recording

6.5 G-Sensor and Loop Recording
The built-in G-sensor automatically detects collisions and locks the corresponding video footage to prevent it from being overwritten. Loop recording ensures continuous recording by overwriting the oldest unlocked files when the memory card is full. The included 64GB SD card provides ample storage, and the system supports cards up to 512GB.
