Video Content Analyzes (VCA)

The camera has integrated Video Content Analyzes
(VCA) which detects and analyzes changes in the
picture using image processing algorithms. Such
changes can be due to movements in the camera's field
of view. Detection of movement can be used to trigger
an alarm and to transmit metadata.
Various VCA configurations can be selected and
adapted to your application, as required.
Refer to Setting up VCA for more information on setting
up video content analyses.
Note
If there is not enough computing power, priority is given
to live images and recordings. This can lead to
impairment of the VCA system. Observe the processor
load and optimize the encoder settings or the VCA
settings if necessary, or turn off VCA completely.

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.
Audio alarm
Select On for the device to generate audio alarms.
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.

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.

e-mail in the event of an alarm.
Mail server IP address
