Privacy Zones
In order to use private zones in WinCC OA, the parameter privacy is used for the camera configuration.
- In WinCC OA in the Camera Configuration dialog: add under Parameter.
- The parameter privacy must be created in WinCC OA. To do this, confirm the following dialog:
- In the WinCC OA Configuration panel click on Apply and then confirm by clicking on OK to apply the changes.
Syntax and Pixel Resolution
The syntax for the privacy parameter is: privacy=<Width>,<Height>@<X Position>,<Y Position>
.
These values are relative in percent, i.e. value 100 means full width/height. X-position and Y-position are relative to the upper left corner of the rectangle.
privacy=50,50@25,25
results in a rectangle that occupies 50% of the width and height and whose upper left corner sits at 25% - thus "centered" accordingly.
To define multiple zones, the areas are concatenated using +: privacy=20,20@20,20+20,20@60,60
Colored Areas
As an alternative to pixelation, it is also possible to configure full-surface privacy zones. In this case, the rectangle definition is extended by the parameter R0C followed by a color definition in hex notation.
For example: privacy=42.18,69.22@36.78,27.75R0Cff0000
