AXIS M30 Series
Setup
A privacy mask is a user-defined area that prohibits 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 are present on all snapshots, recorded video, and requested streams. They can not be bypassed through the VAPIX®
application programming interface (API).
Important
If you add many privacy masks, this may affect the product's performance.
How to create a privacy mask
To create or edit a privacy mask, go to Settings > Privacy mask .
