Step 5: Post-Update Procedures

The update is complete, but your job isn't done. Performing these checks ensures a smooth transition.

Common Firmware Issues & Limitations

  1. No RAID: As a "Lite" series NVR, the firmware does not support RAID storage.
  2. Camera Compatibility: While it supports ONVIF cameras, the firmware works best with Dahua cameras. Third-party ONVIF cameras may lose connection frequently or fail to show stream 2 (sub-stream) if the "Compatibility Mode" is not toggled in the settings.
  3. Updates: The UI for firmware updates is manual. You must download the .bin or .dav file from the Dahua website (or your OEM provider) and upload it via the web interface. There is no "One-Click Update" button in the UI.

5. Common Firmware Issues & Mitigations

| Issue | Cause | Solution | |-------|-------|----------| | “Upgrade failed – mismatch” | Wrong hardware version | Verify PCB revision; use region-specific firmware (e.g., NA, EU, CN). | | PoE ports stop working | Firmware reset PoE controller | Reboot NVR, power-cycle cameras. | | Web interface becomes slow | Browser plugin deprecation | Use Edge IE mode or Dahua SmartPSS. | | NVR won’t boot after upgrade | Corrupt flash / wrong bootloader | Requires serial recovery via TFTP (advanced). |

Prerequisites:

  • USB Thumb Drive formatted to FAT32 (not NTFS or exFAT).
  • Uninterruptible Power Supply (UPS) recommended – a power loss during update kills the NVR.
  • Backup your configuration: Go to Settings > System > Backup & Restore > Export.

Method A: USB Flash Drive Update (Recommended)

  1. Format the USB drive to FAT32 (NTFS and exFAT are not recognized by most NVRs).
  2. Copy the firmware file (e.g., General_NVR4xxx_4.002.230101.bin) to the root directory of the USB drive. Do not put it inside folders.
  3. Insert the USB drive into an available USB port on the NVR.
  4. On the NVR interface, go to Main Menu > System > Upgrade.
  5. Select the USB tab. The NVR should detect the file.
  6. Click Upgrade. The NVR will verify the checksum of the file.
  7. Crucial: Once the progress bar appears, do not touch any buttons, do not power off, and do not remove the USB drive. The NVR will reboot automatically.
  8. After reboot, go back to System Info to confirm the new version number.

How to Match Hardware Revision

  1. Look at the physical sticker on the bottom or back of your NVR. You will see a model number like NVR4108H-8P-X. The suffix (e.g., -3.5) indicates the hardware revision.
  2. On the download page, filter by your exact hardware revision. For example, firmware for NVR4108H-8P-3.5 will not work on an older NVR4108H-8P-2.0.
