Privacy Mask
A privacy mask is an area of solid color that prohibits users from viewing parts of the monitored area. Privacy masks cannot be bypassed via the VAPIX® Application Programming Interface (API).
The Privacy Mask List, Video > Privacy Mask, shows all the masks that are currently configured in the Axis product and indicates if they are enabled.
Since the Pan/Tilt/Zoom coordinates define its size and position, a privacy mask is dynamic in relation to the monitored area. This means that regardless of the angle and zoom of the lens, the same place or object will be hidden. To define at what magnification the mask should be displayed, zoom to the desired level and click Set level.
You can add a new mask,
