5.10 Event handling
Various types of events change the way the unit works. These events are:
– a contact input signal applied to the unit;
– motion detection in a camera signal;
– a loss of video from one of the cameras;
– an internal alert from the unit itself (i.e. disk failure, temperature alarm).
– a text string sent to the unit to be recorded with one or more cameras.
The way the unit reacts to events depends on how it is programmed.
An event can change the way the unit works and, if it is an alarm, can require a response from
the user.
Background events
Events can change background tasks that a user may not notice. Unit responses that are not
visible to the user are, for example, a change in recording speed, the activation of the output
relay, or event logging. The unit can also be configured to record upon the activation of an
event or it might change the way the camera images are displayed on the monitors without
requiring user intervention.
5.10.1 Alarms
An alarm can cause the unit to react as follows:
– A beeper sounds.
– A status message is displayed.
– An alarm icon is displayed.
– The border around a cameo changes color to red.
– An alarm indicator, a motion indicator or a video loss indicator flashes.
– The indicator on the key flashes.
– An output relay is activated.
– The view modes on the monitors change.
– A controllable camera might be moved to a pre-defined position.
– Recording behavior changes.
– The unit changes the way it operates via pre-defined profiles.
Acknowledging an alarm
Press the acknowledge key to acknowledge the alarm or use the mouse to click
on the on-screen button panel.
– The beeper is silent.
– The alarm and indicators are no longer lit.
– The alarm status message disappears.
– The last-used view mode is restored.
The alarm icon remains visible as long as the input causing the alarm is active.
If an alarm is not acknowledged, the beeper switches off after the dwell time but the alarm
still needs to be acknowledged.
If auto-acknowledge is enabled, the beeper and the alarm and indicators,
switch off after the dwell time.
