System Upgrade
Upgrade the NVR under Maintain > Upgrade locally (using an upgrade file
saved in a USB storage device) or by cloud (through a cloud server).
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.
15 Shutdown
Click Shutdown to log out, restart or shut down as needed. To shut down
the NVR, you may also long-press the power button on the front panel (if
available) for around three seconds till an on-screen message appears,
and then click Yes.
CAUTION!
Unsaved settings will be lost if the NVR is shut down unexpectedly, for
example, due to a power failure. An incorrect shutdown during a system
upgrade may cause startup failures.
