4. Operating Instructions
4.1 Automatic Recording
The dash cam automatically starts recording when your vehicle's ignition is turned on and stops when the ignition is turned off. Footage is saved to the MicroSD card.
4.2 Loop Recording
The S1 Pro utilizes loop recording, continuously overwriting the oldest unlocked footage when the MicroSD card is full. This ensures uninterrupted recording. You can adjust loop intervals (1, 2, 3, or 5 minutes) in the settings.

4.3 G-Sensor (Emergency Lock)
The built-in G-sensor detects sudden impacts or collisions. When triggered, it automatically locks the current recording segment to prevent it from being overwritten by loop recording. These locked files are stored in a separate folder.

4.4 24-Hour Parking Mode
For continuous monitoring while parked, the dash cam offers a 24-hour parking mode. This feature requires a hardwire kit (not included, ASIN: B0CRHJQ3WQ) to provide constant power to the dash cam. In parking mode, the camera uses time-lapse recording to save storage space and can detect motion or impact to trigger event recording.

- View live footage from both cameras.
- Download recorded videos to your phone.
- Share footage directly from the app.
- Adjust dash cam settings.

5. Maintenance
5.1 MicroSD Card Formatting
Regularly format your MicroSD card (e.g., once a month) to maintain optimal performance and prevent data corruption. This can be done through the dash cam's settings menu or the Miofive app. Important: Formatting will erase all data on the card, so back up any important footage beforehand.
5.2 Supercapacitor Design
The S1 Pro uses an upgraded supercapacitor instead of a lithium battery. This design allows the dash cam to withstand extreme temperatures, ensuring reliable operation in both hot summers and freezing winters without concerns about battery overheating or degradation.
