Privacy masking
Sensitive areas or movements in the image can be hidden by a mask. This prevents the user from seeing these areas. Depending on the user authorizations, the mask is displayed in surveillance mode and archive mode.
This function can be activated and disabled in
surveillance
mode and archive mode
by administrators and users with corresponding rights.
- Activate privacy
masking.
- Select the Static
objects or Scrambling control.
- You can use the Static objects method to mask fixed individual areas of the camera image. The masking follows the camera so that it is always the same image detail that is masked.
- The Moving objects method of the Scrambling function allows you to mask moving objects or people. Office mode of the Scrambling function masks all differences from a reference image.
Static objects
- Select
the Static objects function and select
the shape of the area to be hidden.
- Select the transparency,
color and shape of the mask, and then drag the shape over the camera image.
You can select either Delete to delete a
single masking or Delete all to delete
all of them.
Moving objects
- Select
the Scrambling function and specify how
long the object is to be masked for after it comes to a halt (Masking
duration), the pixel size to be used for masking (Masking)
and how sensitive the response is to a moving object (Sensitivity).
- Select Black
and white to display the mask in black and white. Otherwise, the
mask is displayed with coarse pixels in the original colors.
Office mode
- Select
Office mode, and then load a reference
image. All differences to the stored reference image are masked.
- To delete all masks
in the archive, click Delete history and
then Yes to confirm.
If privacy masks with archived recordings are deleted,
only users with the appropriate permissions are able to see the recordings.
