Note
Depending upon the camera model used, two events can be used
each as triggers for an alarm scenario:
Manipulation
: The camera angle is changed or the objective
of the camera is covered.
Video loss
: Connection between analog camera and video
server is lost.
Start (Expert Mode)
The expert mode is only available with the appropriate license. This mode allows
the configuration of complex alarm scenarios. An alarm is triggered under various
conditions that can be combined using the logical operands
AND
or
OR
.
1. Optional: Specify a
precondition
that must be met before an alarm can be
triggered by certain events. Select the input(s) that will be closed or opened,
so that the alarm can be triggered with the
Edit
button in the
Input trigger
conditions for alarms
field.
The operand in this field is
AND
. If an input is disabled, but it is still listed in this
field, then this condition is recognized as
true
and alarm is triggered.
2. In the
Seconds
field, specify the duration in which the following events must
occur to trigger an alarm.
Within the fields, an
OR
link is created; between the fields an
AND
link is
established.
3. With the
Edit
button, select the events in the group fields that will trigger
the alarm (digital inputs closed / opened, SeeTec Network I/O inputs).
Alarms can be triggered via buttons as well. To start an alarm scenario via a
button
, configure it in the tab with the same name. These buttons will then be
listed in the lower
Buttons that trigger the alarm
field.
End
Preliminary exit of an alarm scenario can either take place via option information
Maximum server alarm duration (s)
(= Recording duration of alarm) or via
further triggers (digital inputs, activation via
Edit
button).
You can also terminate an alarm by using a Button. This button must be defined at
a later point of time using the
Buttons
menu option.
