5. Operating Instructions
5.1 Power On/Off
The dash cam powers on automatically when your vehicle's ignition is turned on and powers off when the ignition is turned off. No manual intervention is required for basic operation.
5.2 Recording Modes
- Loop Recording: The camera continuously records video in segments (e.g., 1/3/5 minutes). When the memory card is full, it automatically overwrites the oldest unlocked footage.
- G-Sensor (Emergency Recording): In the event of a sudden impact or collision, the built-in G-sensor detects the event and automatically locks the current video segment, preventing it from being overwritten by loop recording. This ensures critical footage is preserved.

The dash cam features built-in Wi-Fi for seamless connection to the FITCAMX mobile application. This allows you to:
- View real-time video footage on your smartphone.
- Download recorded videos directly to your device.
- Adjust camera settings.
To connect, download the FITCAMX app from your device's app store. Turn off cellular data or Bluetooth on your phone if you experience issues with live preview, as this can sometimes interfere with the Wi-Fi connection. This will not affect CarPlay or Android Auto functionality.
