Triggers and alarms Various types of events can change the way the unit works. These events can be:
• An alarm input signal applied to the unit.
• A motion detection signal from a camera.
• A loss of video from one of the cameras.
• An internal alert from the unit itself.
The way the unit reacts to events depends on how it has been programmed.
An event causes either a trigger or an alarm. A trigger can change the way the
unit works but does not require a response from the user. An alarm can also
change the way the unit works but, in addition, it usually activates several
indicators and requires that the user acknowledges the alarm situation.
The unit can react to an event in any one of the following ways:
Alarms
• A beeper sounds
• A status message is displayed
• An alarm icon is displayed
• The border around a cameo can change color
• An alarm indicator , , or flashes
• The indicator flashes
• An output relay is activated
Alarms and Triggers
• The view modes on the monitors change
• A controllable camera is moved to a pre-defined position.
• Recording speed changes
• The unit changes the way it operates via pre-defined profiles.
Background events
Triggers and alarms can change background tasks that you, as user, may not even
notice. Unit responses that are not visible to the user are, for example, a change
in recording speed, the activation of the output relay and event logging. A trigger
may change the way the camera images are displayed on the monitors without
requiring your intervention.
