You can impose a privacy mask on video to hide parts of the frame from the user in live video. 

In this case, the mask is not superimposed on recorded video.

To configure privacy masking, do the following:

1. Select the Object Tracker object and click the  button.

   For your convenience, you can click the  button and configure the mask on a still frame / snapshot. To undo, click this button again.

   
   

2. In the FoV, set the nodes of the closed area you want to obscure. 

   

   When the area is being constructed, the nodes are connected by a two-color dotted line which outlines the area's borders.
