Upgrade Firmware
1. Make sure there is a recordable hard disk installed in NVR or a USB disk with at least
200MB space connected to NVR.
2. Go to Setup page Maintenance tab Firmware Upgrade. Click “Browse”, find the
target *.upg file and click “Open”.
3. Click “Upgrade”.
During upgrading, the system will stop every other activity including recording and event
handling. The system will auto-restart after the upgrading completes.
As upgrading has started, DO NOT cut off the system power or eject the USB disk until
NVR restarts.
