AXIS Q1775-E Network Camera
Video and Audio
Privacy Mask
A privacy mask is a user-defined area that prevent users from viewing parts of the monitored area. Privacy masks appear as
blocks of solid color or blurred image elements and are applied on the video stream. Privacy masks cannot be bypassed using the
VAPIX® application programming interface (API).
The Privacy Mask List (Video & Audio > Privacy Mask) shows all the masks that are currently configured in the Axis product and
indicates if they are enabled.
You can add a new mask, re-size the mask with the mouse, choose a color for the mask, and give the mask a name.
For more information, see the online help
Important
Adding many privacy masks may affect the product's performance.
