NOTE: If your unit's model number is NVR8-8780RN, follow this article instead: NVR8-8780RN USB Firmware Updates
To check what is your current firmware, access the NVR's Menu then go to System > Information and look for the Software Version. For a NVR8-8780, the latest Software Version is v8.1.0-20220418
Before you try the following procedure, read this article first: How to do OTA update?
If you are unable to use the automatic update service to update the recorder, you can use the following procedure to update manually.
- Prepare a FAT32 flash drive or USB - it needs to be on FAT32 for it to be read; there is no need for an external HDD as the files are small.
- Download the firmware file HERE and save it to your flash drive.
- Unplug the Ethernet cable connected to the NVR then reboot.
- Insert the flash drive to your NVR.
- Access the Menu and go to Advanced > Maintain then click on Upgrade.
- Select the file: N4XXX_V210825V210805V211024V220418V220418V220418V220327.sw and click OK.
- A confirmation window will appear, click on OK again.
- NVR will start to update. Make sure not to unplug the USB or turn off the NVR while it is updating.
NOTE2: If updating the firmware via Menu fails, use Swann Security VMS on a Windows computer. Follow Firmware update for OS 5 recorders via Swann Security VMS (Windows)
