Note : This section of the manual provides an overview of the fields and the options for each
field on the page VCA . This section is not a complete tutorial of setting up VCA . For more
information, refer to the separate manual Video Content Analysis (VCA) , available on the
product page for Intelligent Video Analytics. Access the product page on the online product
catalog from
http://www.boschsecurity.com/corporate/product-catalog/index.html .

the VCA options for the visible camera.

Default to return all settings to their default values. A dialog box
appears with the message, “ Configuration of the video content analysis (VCA) will be reset
to factory defaults. The changes will be lost. Click 'OK' to continue. ” Click OK to
acknowledge the message, or click Cancel .
Alarm status
The alarm status is displayed here for information purposes. This means you can check the
effects of your settings immediately.
Aggregation time [s]
Set an aggregation time of between 0 and 20 seconds. The aggregation time always starts
when an alarm event occurs. It extends the alarm event by the value set. This prevents alarm
events that occur in quick succession from triggering several alarms and successive events in a
rapid sequence. No further alarm is triggered during the aggregation time.
The post-alarm time set for alarm recordings only starts once the aggregation time has
expired.
Analysis type
Select the appropriate option for Video Content Analysis: , Intelligent Video
Analytics, or Intelligent Video Analytics Flow.
Note : When you select another analysis type, a dialog box appears with the message,
“ Changing the analysis type resets motion and tamper parameters. ” Click OK to
acknowledge the message (and to switch analysis types), or click Cancel .
Tamper detection
Detect tampering of cameras and video cables by means of various options. Run a series of
tests at different times of the day and night to ensure that the video sensor is operating as
intended.
Sensitivity and Trigger delay [s] can only be changed if Reference check is selected.
