Sources of Events
• Outside World event. Events triggered by sensors connected to a unit, such as
motion detection or Tamper Detection for cameras.
• Customer-Device event. Messages from a cash register, card swipe and so on, that
can be sent to a Multi-Media unit.
• Multi-Media Unit event. For notifying a Multi SA of events at the unit. Extended power
outages that stop a unit can also be monitored by connecting a Multi-Media unit to an
alarm panel (see
Using an External Alarm Panel with the Fault Relay
• View Operator event. An administrator can trace events caused by View Operators,
such as connecting to a site, and so on. Notification of such events is usually of more
concern than video of that event.
Your Multi SA sets which events can trigger alarms.
Your Multi SA has the option of setting camera Tamper Detection to trigger alarms. If true
sabotage to a camera occurs, the camera will probably need Maintenance after the event.
Let your Multi SA or the system installers know that service is needed.
Alarms
Blind. A camera can be blinded by too much or too little light. Blinding a camera also
triggers the Blur- and scene Changed-type of sabotage detection. Note that turning lights
on and off at the scene can indirectly blind a camera. Panning a PTZ camera from a
light-colored scene to a darker scene (or vice versa) can also have that effect.
Changed. Changed is sensitive to large scale changes in a scene. For example, using
Changed for a camera that shows many empty chairs in a row, close by, such as in an
airport or casino, may trigger an alarm when people sit in the chairs and change the scene.
The same can be said for a row of vehicles that are frequently moved, such as in a taxi stand
or truck depot.
Blur. After Blur-type sabotage, the camera will probably need Maintenance. Let your Multi
SA or the system installers know when Blur-type sabotage occurs.
Forty-Eight Seconds
If Blind-, Changed- or Blur-type activity lasts less than 48 seconds, it does not trigger an
alarm or log entry. This is designed to reduce the number of false positives that are
recorded. For example, a person walking by a camera at close range and blinding the
camera is not considered sabotage unless that person remains in front of the camera for
more than 48 seconds.
