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.
