In Security Center, privacy protection is software that anonymizes or masks parts of a video stream where movement is detected. The identity of individuals or moving objects is protected, without obscuring movements and actions or preventing monitoring.

IMPORTANT: Privacy protection is only supported with native cameras. Moreover, privacy protection cannot be enabled on cameras where recording is performed by a DVR or on the video unit.

Privacy Protector™ role

The Privacy Protector™ role requests original video streams from Archiver roles and applies data anonymization to the original video streams. The privacy-protected (anonymized) video stream is then sent back to the Archiver role for recording.

The Privacy Protector™ role can distribute its workload over multiple servers. This should not be confused with failover, where only one server bears the full load of the role at all times. If one of the assigned servers fails, and the remaining servers cannot handle their increased load, the resulting streams will have dropped frames.

Privacy protection and video streaming

When privacy protection is enabled on a camera, two video streams are generated:

Private stream
The private stream, also known as the confidential stream, is the original video stream from the video unit where the video content is not anonymized or masked.
IMPORTANT: The private stream can only be viewed if the user explicitly requests it and has the Remove privacy protection privilege.
Public stream
The public stream contains privacy-protected content with video anonymization applied. This ensures that all regular access to video will always access the anonymized video.

Using backward compatibility, an older Security Center system (5.6 and earlier) federating a privacy-protected camera can only view the anonymized stream.

NOTE: When you export video, the stream displayed in the tile is used. If you request to remove privacy protection, the confidential video is exported.

Other considerations

  • The Auxiliary Archiver only records the public (anonymized) streams. Only the Archiver records the private (confidential) streams.
  • If you activate encryption on the camera, only the private stream is encrypted.
