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.
