Event triggered
This configuration allows you to stipulate that the video content analysis is only to be
activated when triggered by an event.

As long as no trigger is activated, the Silent VCA configuration in which metadata is created is
active; this metadata facilitates searches of recordings, but does not trigger an alarm.
Trigger
Select a physical alarm or a virtual alarm as a trigger. A virtual alarm is created using software,
with RCP+ commands or alarm scripts, for example.
Trigger active
Select the VCA configuration here that is to be enabled via an active trigger. A green check
mark to the right of the list field indicates that the trigger is active.
Trigger inactive
Select the VCA configuration here that is to be activated if the trigger is not active. A green
check mark to the right of the list field indicates that the trigger is inactive.
Delay [s]
Select the delay period for the reaction of the video content analysis to trigger signals. The
alarm is only triggered after a set time interval in seconds has elapsed and then only if the
triggering condition still exists. If the original condition has been restored before this time
interval elapses, the alarm is not triggered. A delay period may be useful in avoiding false
alarms or frequent triggering. During the delay period, the Silent VCA configuration is always
enabled.

Audio Alarm

Alarms can be generated based on audio signals. Configure signal strengths and frequency
ranges so that false alarms, for example, machine noise or background noise, are avoided.
Set up normal audio transmission before configuring the audio alarm.

Name
The name makes it easier to identify the alarm in extensive video monitoring systems. Enter a
unique and clear name here.
Signal Ranges
Exclude particular signal ranges in order to avoid false alarms. For this reason the total signal
is divided into 13 tonal ranges (mel scale). Check or uncheck the boxes below the graphic to
include or exclude individual ranges.
Threshold
Set up the threshold on the basis of the signal visible in the graphic Set the threshold using
the slide control or, alternatively, move the white line directly in the graphic using the mouse.
Sensitivity
Use this setting to adapt the sensitivity to the sound environment and effectively suppress
individual signal peaks. A high value represents a high level of sensitivity.
Click Set to apply the changes.

Alarm E-Mail

Alarm states can be documented by e-mail. The camera automatically sends an e‑mail to a
user-defined e‑mail address. This makes it possible to notify a recipient who does not have a
video receiver.
