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. 

Note

  • When you delete a replicated face from the Server's face database, this face will be deleted only from this Server.
  • When you delete a face from the Server's face database (replication source), this face will also be deleted from all Servers that replicate this face database.

Attention!

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 recognition parameters of captured faces).

Otherwise, some photographs of faces from the main Server will not be added to other Servers, and there will be an increased load on the network and computing resources. Photos of faces that cannot be added to other Servers can be saved on the main Server in a folder. To do this, it is necessary to change the value of the LogBadImages parameter to True (see XML-file parameters reference guide).

Face database replication is configured as follows:

  1. Activate the Face database replication module (see Activation of the recognition modules in Face PSIM). 
  2. Go to the settings panel of the Face database replication object.
  3. In the Sources for replication list (1), set the checkboxes for the Face recognition servers, the following data from which will be replicated to the current Face recognition server:
    1. Face DB (2)—for replication of the reference face database;
    2. Face captures (3)—for replication of the captured faces database.
  4. In the Replication interval, s field (4), specify in seconds how often the reference face database and/or captured faces database will be replicated (default is 10 sec).
  5. In the Number of elements field (5), set the maximum number of reference face database and/or captured faces database records that can be replicated at a time (default is 1000).
  6. Click the Apply button (6) to save the settings.

The face database replication is configured.
