The face database replication is used in a distributed configuration with several Servers, so that when new faces are added from the face database of the selected Server (the replication source), the same faces are automatically added to the face database of other Servers in the distributed configuration. Also, when the face database replication is activated, the changes on the selected Server (the replication source) of such data as photo, name, last name or comment are also synchronized with other Servers.

To ensure the proper operation of the face database replication, the following conditions should be met:

  1. All Servers should use the same face recognition modules, and their SDK should be the same version.
  2. All Servers should have the same value for the Minimum quality for adding face to DB (0-100) parameter (see Configuring the captured faces recognition parameters).

Otherwise, some photographs

To do this, it is necessary to change the value of the LogBadImages parameter to True (see XML-file parameters reference guide).
