8.5.3 Privacy mask
The privacy masking is only activatable and configurable when a view mode is
selected which contains a fisheye view.
This means that privacy masking is not available in the Panorama / Double
Panorama module and 4xPTZ mode.
You can use privacy masks to hide certain areas in the live view to prevent these areas from being recorded
and viewed in the live view. A maximum of four rectangular privacy masks can be set up in the video image.
To set up a privacy mask, proceed as follows. Select the checkbox
"Enable Privacy Mask". To add a privacy mask, click "Draw Area". You can now select an area on the camera
image using your mouse. You can then select three additional areas. By clicking on "Clear All", you can delete
all configured privacy masks.
Apply the settings by clicking "Save".
