Updating your NVR Firmware

Periodic system checks should include checking for system updates. This can be done by right-clicking on the main camera screen, selecting Menu, then navigating to Maintain. From here,you can upgrade the system with a USB, or automatically by cloud.
 
To upgrade by cloud, ensure that the NVR is connected to a fully functional DNS server (configured under System > Network > Basic), and click Check to see whether a newer version is available. The time that a cloud upgrade takes is affected by network connection status.
CAUTION: Make sure power is not interrupted during upgrade. A power failure during system upgrade may cause startup failure. Use an Uninterrupted Power Supply (UPS) if necessary.
 
Ensure network connectivity for a cloud upgrade.
