If your cameras support PTZ functionality, you can control them directly from the NVR interface:
- Right-click on the NVR screen to open the main menu.
- Select "PTZ Control".
- Use the on-screen controls to pan, tilt, or zoom the camera.
5.3 Motion Detection & Alerts
The system supports human detection and can send accurate alerts:
- Access the NVR's main menu and navigate to "Face detection" or "Motion Detection" settings.
- Configure detection zones, sensitivity, and alert actions (e.g., push notifications to mobile app, local alarm).
- When motion or human presence is detected, the system will trigger alerts and record events.

5.4 Mobile App Connection (ICSee)
To view your cameras remotely on your smartphone or tablet, download the ICSee app:
- Download the "ICSee" app from your device's app store (available for iPhone OS and Android).
- Open the app and register an account.
- On the NVR screen, navigate to the network settings or device information to find the QR code.
- In the ICSee app, select "Add Device" and choose the "Scan QR Code" option.
- Scan the QR code displayed on the NVR screen.
- Follow the on-screen prompts in the app to complete the connection.

5.5 Multi-User Sharing
You can share access to your camera system with family and friends through the ICSee app:

6. Maintenance
6.1 Hard Drive Management
- **Formatting**: It is recommended to format a newly installed hard drive through the NVR's system settings before first use.
- **Storage Capacity**: The system uses H.265 compression, which is more efficient than H.264, allowing for more storage on the same size hard drive. For example, 1TB with H.265X is equivalent to 2TB with H.264.
- **Regular Checks**: Periodically check the hard drive status in the NVR settings to ensure it's functioning correctly.

6.2 Cleaning
- Use a soft, dry cloth to clean the NVR screen and camera lenses.
- Do not use liquid cleaners or aerosol sprays directly on the devices.
6.3 Software Updates
Check the NVR system settings or the ICSee app periodically for available firmware updates to ensure optimal performance and security.
7. Troubleshooting
- **NVR Screen "Not Connected"**:
- Ensure all cameras are powered on and within range of the NVR's WiFi.
- Re-attempt the "QuickPair" process (Section 4.3).
- Check network cable connection if using wired cameras or for NVR internet access.
- **"No Available Storage for Recording" Message**:
- Verify a 2.5-inch HDD or Micro SD card is correctly installed and formatted.
- Check if the storage device is full; consider backing up and formatting or replacing it.
- Ensure cloud storage subscription is active if relying on it.
- **No Image on External Monitor**:
- Check the HDMI cable connection between the NVR and the monitor.
- Ensure the monitor is set to the correct input source (HDMI).
- **Mobile App Connectivity Issues**:
- Ensure the NVR is connected to the internet (via WiFi or Ethernet).
- Verify your smartphone has a stable internet connection.
- Re-scan the QR code or re-add the device in the ICSee app.
- Check if the NVR's network settings are correct.
- **Poor WiFi Signal/Interference**:
- Position the NVR and cameras to minimize obstacles (walls, large metal objects).
- Ensure the NVR is not too far from the cameras. The system supports stable connection up to 30m in open environments.
- Avoid placing the NVR near other 2.4GHz wireless devices that might cause interference.
