General information

A privacy mask is an area that hides certain parts of the frame to ensure privacy. For example, when cameras are installed in an office, you can use a privacy mask to cover employees' computer screens to prevent the leak of logins, passwords and other sensitive information. In critical infrastructure, you can use a privacy mask to hide sensitive elements such as control panels and screens containing critical data.

You can apply a privacy mask to the video image:

  • when viewing live videos;
  • when viewing the archive;
  • on exported videos and still frames.

Attention!

  • Privacy mask is displayed for all users who have the View masked video parameter set to No in the role configuration (see Roles).
  • Privacy mask is displayed in the client only. In the Web-Client and the Mobile client, there is no mask on the video image.

To configure a privacy mask, do the following:

    • The button is inactive, if the text overlay button is active (see Putting a text over the Surveillance window). 
    • For your convenience, you can click the  button and configure the mask on a still frame. To undo, click this button again.

  2. In the preview window, sequentially set the anchor points of the closed area that you want to hide when viewing the live video image.
