Alive Monitoring
The System Server checks whether Matrix Switchers, Hard Disk Recorders, IP cameras, Network Disk Recorders
and IP Encoders are alive or not. Users can know the status of these devices in WV-ASM970 Operation Screen and
see the logs of alive monitoring in WV-ASC970 Admin Console's Log Manager screen.

WJ-ND400 Backup System
When an ASC970 Server detects that Main WJ-ND400 becomes offline or their all hard disk drives become failure,
the ASC970 Server sends the latest configuration data of Main WJ-ND400 to Backup WJ-ND400.

Priority Rules
●
Basic Rule
The System Server has the First-Come-First-Serve rule by default when there are same-priority conflicts.
The administrator also can select the Last-Come-First-Serve rule by WV-ASC970 Admin Console.
The First-Come-First-Serve rule is always applied to seizing video links without regard to operator's priority.
●
Operator Priority
Operators are controlled by two types of priority. One is Operator priority and other is Controller priority. For priority
conflicts between operators, the Server looks first at Operator priority, then at Controller priority.
●
Alarm, Schedule and Operator Priority
Between alarm, schedule and operator, alarm carries the highest priority, next is schedule and last is user.
●
Global Operator and Local Operator
Only Global Operator can access other domain devices such as camera, recorder and tour sequence. Global
Operator is applied same priority rule as well as Local Operator except global access.
●
Playback and Camera Control
When a user controls a camera, another user who has lower priority can play back the Digital Disk Recorder or
Network Disk Recorder.
When a user plays back the Digital Disk Recorder or Network Disk Recorder, another user who has lower priority
can control the camera even if the user priority is lower.
Note:
• In case of Network Disk Recorder, when a user starts the playback, the System Server makes the user priority
go down the lowest in order for another user to be able to control the camera. And when the user stops the
playback, the server returns the priority to the original. By this manner, if the both user priorities are same, the
user who starts the playback will have camera busy after stop the playback.
