5.1 Automatic Recording

7. Parking Monitoring

8.2 G-Sensor
The built-in G-Sensor detects sudden acceleration, braking, or collisions. Upon detection, it automatically locks the current video segment, moving it to an emergency folder to prevent it from being overwritten by loop recording. These locked files serve as critical evidence.
