Operating Instructions

Connecting via Wi-Fi and Using the App:

- Download the "FITCAMX" app from the Apple App Store or Google Play.
- Turn on your vehicle's ignition to power the dash cam.
- On your smartphone, go to Wi-Fi settings and connect to the dash cam's Wi-Fi network (SSID and password can be found in the dash cam's settings or manual).
- Open the FITCAMX app. You can now view real-time footage, access recorded videos, and adjust camera settings.
- You can download important video data directly to your smartphone for easy playback and sharing.
Recording Features:
- Loop Recording: The dash cam continuously records. When the memory card is full, the oldest video files are automatically overwritten by new recordings. This ensures continuous recording without manual intervention.
- G-Sensor (Emergency Lock): The built-in G-sensor automatically detects sudden impacts or collisions. When an event is detected, the current video segment is automatically locked and saved to a protected folder, preventing it from being overwritten by loop recording. This ensures critical incident footage is preserved.
- Video Quality: The dash cam records in high resolution (Front: 2160P, Rear: 1080P) at 30 frames per second. Wide Dynamic Range (WDR) technology ensures clear and vivid recordings even in challenging lighting conditions, such as at night or in strong sunlight.
Maintenance

- Cleaning: Use a soft, dry cloth to clean the camera lens and the main unit. Avoid using abrasive cleaners or solvents that could damage the device.
- Memory Card: Regularly format the memory card (at least once a month) using the FITCAMX app or a computer. This helps maintain card health and prevents data corruption. A 64GB memory card is included, and the device supports up to 128GB.
- Firmware Updates: Check the FITCAMX official website or app periodically for firmware updates. Keeping the firmware updated ensures you have the latest features and bug fixes.
- Operating Environment: The device is designed to operate in temperatures ranging from -20°C to 85°C (-4°F to 185°F). Avoid exposing the device to extreme temperatures outside this range for prolonged periods.
