All metadata is stored in the SQL database. The compiled films from the recordings and the data from the file transfer are stored in the local file system on the Visulox system. The server containing this data is in the access environment of the data center (Access Zone). This would be an access possibility for the pUser to the recordings and could risk tampering.
 To prevent this, VXS allows to use a revision server to which only the audit department has access to. The module Visulox revision continuously replicates the data of the VXS from the Access zone on its second database, and thus eludes the access of the pUser.
