Advanced system reset (10 sec)
After pressing the reset button for 10 seconds, you will hear two beeps at the third
and the tenth seconds. The NVR will reset all the system settings to default as it does
by the web-based system reset in “Administration” > “Restore to Factory Default”
except all the data are reserved. The settings such as the users, user groups, and the
shared folders previously created will be cleared.
Enable light signal alert when the free size of SATA disk is less than the value:
The status LED flashes red and green when this option is turned on and the free
space of the SATA hard drive is less than the value. The valid range of the value is
1-51200 MB.
Enable warning alert for redundant power supply on the web-based interface:
If two power supply units (PSU) are installed on the NVR and connected to the power
sockets, both PSU will supply the power to the NVR (applied to 1U and 2U models).
Turn on the redundant power supply mode in “System Settings” > “Hardware” to
receive warning alert for the redundant power supply. The NVR will sound and record
the error messages in “System Logs” when the PSU is plugged out or does not
correspond correctly.
If only one PSU is installed on the NVR, do NOT enable this option.
