In Security Center, privacy protection is the software technology that is used to blur or mask parts of a video stream. Anything that is moving and analyzed as not being part of the background in the scene is blurred or masked to protect the identity of individuals or moving objects without obscuring movements or actions so that monitoring can still occur.

Privacy Protector role

The Privacy Protector™ role is responsible for performing analytic operations on streams. It is a media processing role that requests the original video from the Archiver and modifies the stream to apply confidential video anonymization. The privacy-protected (anonymized) video stream is then sent back to the Archiver for recording.
  • You must have a Privacy Protector license and at least one Privacy Protector role must exist to use the privacy protection feature.
  • There is no load balancing. The role works like the Archiver, if an agent is unavailable the next available one is used. If a server fails, all of the work is transferred to a failover server.
  • The Privacy Protector role also provides the blurred or masked public video stream to clients.
NOTE: Using backward compatibility, previous Security Center versions can view the protected streams (through Federation™), but not the original ones. This also applies to previous versions of Media Gateway (RTSP streams) and the Web Client.

Privacy protection streams

When privacy protection is enabled in the camera configuration, two video streams are archived:

  • Video stream (Public) - contains privacy-protected blurred content with video anonymization applied. This ensures that all regular access to video will always access the blurred video.
  • Confidential video stream (Private) - contains the original video stream from the video unit and the video content is not blurred or masked.
    NOTE: The confidential stream can only be viewed if the user explicitly requests it and has the Remove privacy protection privilege.
NOTE: When export video is used, the stream displayed in the tile is used. If privacy protection is removed, the original video is exported.
