4. Operating Instructions
4.1 Basic Recording
Once powered on, the YI Mini Dash Cam C1B automatically begins continuous loop recording. Video segments are typically 1 or 3 minutes long. When the MicroSD card is full, the oldest unprotected files will be overwritten by new recordings.
4.2 G-Sensor and Emergency Recording
The built-in G-Sensor detects sudden impacts or rapid acceleration/deceleration. When triggered, the dash cam automatically saves the current recording segment and locks it to prevent overwriting. These emergency files are stored in a separate folder on the MicroSD card. You can adjust the G-Sensor sensitivity in the settings.
