Configure a privacy mask

You can use a privacy mask to obscure areas in the camera view. A privacy mask obscures video (live and historical) so that a viewer cannot identify objects but allows the Senstar Symphony Server to analyze the video for alarms.

A static privacy mask obscures a defined area of the camera view. A dynamic privacy mask obscures tracked objects.

Privacy masks for PTZ cameras also include a location list and a slider that allows you to zoom in on an image.

  1. In the Senstar Symphony Server configuration interface, click Devices > Cameras.
  2. Select a camera and click Edit.
  3. In the Privacy Mask section, perform the following tasks:
    1. In the Enabled list, select whether the privacy is static, dynamic, or both.
    2. In the Mask Delay field, set how long (in seconds) the Senstar Symphony Server remembers the position of tracked objects and continues to obscure the previous location of a tracked object.
      This setting only applies to dynamic privacy masks.
    3. On the % Surrounding Object slider, select the area beyond a tracked object to which the Senstar Symphony Server applies the privacy mask.
      This setting only applies to dynamic privacy masks.
    4. On the Blur Amount slider, select to what degree the Senstar Symphony Server obscures the camera view.
