Q3: My NVR is a rebranded model (e.g., Lorex). Can I use Dahua firmware?

Usually not. Rebranded devices have modified hardware IDs. Flashing generic firmware will likely fail or brick the unit. Use the rebrander’s official firmware.

Method 2: USB Local Update (if network is down)

Copy firmware .bin to a FAT32 USB drive.
Plug USB into NVR’s USB port.
From NVR local GUI: Main Menu → Maintenance → Upgrade → Select USB file.

Q5: My firmware update failed at 90% – what do I do?

Do not power off. Wait 30 minutes. If still stuck, power cycle. If the NVR is unresponsive, contact Dahua support for recovery instructions. You may need to boot from a recovery USB.

Method 1: Web Browser (Recommended)

Log in to the NVR’s web interface (HTTP port 80 – e.g., http://192.168.1.108).
Go to Maintenance → Upgrade.
Browse to the .bin firmware file.
Click Upgrade – the device will reboot automatically (takes ~5 minutes).

Q1: Can I update using a network share (NFS/SMB)?

No. The DHI-NVR1108HS-8P-S3/H only supports USB or local web upload for firmware updates. Copy firmware

Best Practices for Maintaining Your NVR Firmware

Update only when necessary. If your system is stable and secure, you don’t need every update. Focus on security patches and critical bug fixes.
Read release notes before updating. Look for known issues affecting your setup.
Test updates on a spare NVR if you manage a large deployment.
Keep a copy of the working firmware on your computer in case you need to revert.
Disable auto-update (if available) – manual updates are safer.
Change default password after any update that resets credentials.
Regularly check Dahua’s security advisory page for urgent patches.
