8.8 VCA
This section describes the setting options for video content analysis (VCA) functions. The video analyses are
carried out with the data of the thermal image channel. The following functions are available as rules for the
analysis:
1. Tripwire-> Detection of a line crossing by an object
2. Intrusion-> Detection of an object entering an area with delayed triggering
3. Area entry-> detection of an object entering an area
4. Area exit-> Detection of an object leaving an area that had previously entered the
area.
8.8.1 Basic settings
Intelligent analysis: Activates the VCA analysis function. Further setting steps are necessary.

8.8.2 Camera calibration
Calibration is used to more accurately determine the size of people in the scene being viewed.
Before you begin:
● Make sure that the actual size of the target in the scene is known
● Make sure that there are no moving objects in the view other than the person
If you want to improve the VCA detection, an automatic calibration must be carried out first. If the result of the
automatic calibration is not sufficient, a manual calibration can be performed.
The reference image of the manual calibration appears only after the automatic calibration has been
completed.
Automatic calibration
Set target height: Enter the height of the person (default: 1.70 m)
Start calibration:The automatic calibration can be started via the playback symbol.
