Description

Control Center

As previously described, the Control Center is the main access point to major

 

functionalities.

Disk Status

Disk Status provides a glimpse of Logical Volumes, Physical disk statuses, HDD status

 

reported through S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology), and

 

a test tool to check the integrity of individual disk drives.

 

 

Network Status

Displays the network statuses of the NVR's two GbE Ethernet ports, including network

 

type, IP address, subnet, and gateway information.

System Status

Reports system overall working status.

 

 

Most of the NVR's major functionalities are managed through the LiveClient and Playback interfaces, refer to Chapter 4 for descirption of auxiliary functions.

The operating system and VAST server are installed on an IDE flash mounted on the main board. There is no need to install software.

Except for LiveClient and Playback, detailed description of the auxiliary functions can be found in Chapter Four started from page 187.

Alarm Sound

The onboard buzzer will sound if the following occurs: A hard drive is removed or if the LAN or WAN port is disconnected. Mute the alarm by closing the event prompt.

The hard disk reported as "failed" via S.M.A.R.T. will also trigger the alarm sound and a warning message.
