UPS Configuration
Connect the UPS to the NVR’s USB port for sending and receiving
signals between the UPS and the NVR. The NVR can receive signal
from the UPS when there is a power failure and shut down itself
automatically within a period of time. You can enable UPS support to
prevent data loss when an unexpected power failure occurs.
To enable local UPS support (NVR acting as UPS server):
1. Connect the compatible USB UPS to the NVR
2. Turn on the NVR
3. Go to “NVR Setup” >> “System Options” >> “UPS Configurations”,
and check “Enable UPS Support” option.
You can adjust how long the UPS stays on to provide backup electricity
to the NVR after a power failure by choosing one of the options from
the drop-down shown below:
* Currently only APC Smart-UPS 750 is supported (05282012)
