Privacy masks

How to hide parts of the image with privacy masks
What is a privacy mask?
A privacy mask is a user-defined area that prevents users from viewing a part of the monitored area. In the video stream, privacy
masks appear as blocks of solid color or blurred image elements.
The privacy mask is relative to the pan, tilt, and zoom coordinates, so regardless of where you point the camera, the privacy
mask covers the same place or object.
You'll see the privacy mask on all snapshots, recorded video, and live streams.
You can use the VAPIX® application programming interface (API) to turn off the privacy masks.
Important
Using multiple privacy masks may affect the product's performance.
