5. Operating Instructions
The FITCAMX dash cam operates automatically upon vehicle startup. For advanced features and settings, use the dedicated FITCAMX mobile application.
5.1 Wi-Fi Connection & App Usage
To connect your dash cam to the FITCAMX app:
- Ensure the dash cam is powered on (vehicle ignition is on). The indicator lights on the dash cam will illuminate.
- On your smartphone, open Settings and navigate to Wi-Fi.
- Select the Wi-Fi network name starting with "CAR", "LHD", or "CARDV".
- Enter the default password: 12345678.
- Once connected, open the FITCAMX application. You should see a live view from the dash cam.
- Within the app, you can view live footage, access recorded files, download important videos to your phone, and adjust camera settings.
Note: You cannot connect to the dash cam's Wi-Fi and use Apple CarPlay/Android Auto simultaneously. However, the camera records automatically, so continuous Wi-Fi connection is not required for recording.

5.3 Loop Recording
The dash cam features automatic loop recording. When the memory card is full, the oldest video files will be overwritten by new recordings. You can set the duration of each recording segment (e.g., 1, 3, or 5 minutes) within the FITCAMX app settings.
- A 64GB SD card typically provides approximately 5 hours of recording.
- A 128GB SD card typically provides approximately 10 hours of recording.

5.4 G-Sensor (Emergency Recording)
The built-in G-sensor detects sudden movements, impacts, or collisions. When such an event occurs, the dash cam automatically locks the current video segment, preventing it from being overwritten by loop recording. This ensures critical footage is preserved as evidence.

5.5 Parking Mode (Optional Upgrade)
The dash cam supports an optional parking mode for continuous surveillance when your vehicle is parked. This feature requires a separate hardwire kit (not included in the standard package) to connect to your vehicle's fuse box or On-Board Diagnostics (OBD) port.
- Cable to Fuse Box: Enables non-24h recording.
- Cable to On Board Diagnostics (OBD): Enables both 24h and non-24h recording.

5.6 Night Vision
Equipped with a CMOS sensor and Wide Dynamic Range (WDR) technology, the FITCAMX dash cam provides clear night vision, ensuring high-quality recordings even in low-light conditions.

6. Maintenance
6.1 SD Card Formatting
Regularly formatting the SD card helps maintain optimal recording performance and prevents data corruption. You can format the SD card through the FITCAMX application settings. Warning: Formatting will erase all data on the SD card. Ensure you have backed up any important files before proceeding.
6.2 General Care
- Keep the camera lenses clean using a soft, lint-free cloth.
- Avoid exposing the dash cam to extreme temperatures outside its operating range (-20°C to 85°C / -4°F to 185°F).
- Ensure the dash cam is securely mounted to prevent vibrations or dislodgement.
7. Troubleshooting
Here are solutions to common issues you might encounter:
- Q: How to ensure the correct model?
A: Please compare your vehicle style, year, and the shape of your rearview mirror cover. Alternatively, contact FITCAMX for detailed confirmation. - Q: Can I use CarPlay/Bluetooth when driving?
A: Yes. Your phone cannot be connected to CarPlay/Bluetooth and the dash cam's Wi-Fi simultaneously. However, the camera records automatically after the car starts, so you do not need to keep Wi-Fi connected to the camera at all times for recording. - Q: Can I add a rear camera if I already have a front cam?
A: No, because the PCB boards are different. If you wish to change video resolution or add a rear camera, you would need to replace the entire set.
