3. Select a Trigger and, optionally, a Schedule and Additional conditions. See the online help for details.
4. From the Actions list, select Overlay Text

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 and are applied on the video stream. Privacy masks cannot be bypassed using the VAPIX® application programming
