I would like to have loggings when a user enters playback mode and which camera he’s viewing in playback mode. Is this possible with XProtect Corporate?
Yes. This is possible.
The Audit Log will do this if you enable user access logging..
In the Management Client - Tools - Options - on the Server Logs tab pick the Audit Log and adjust the setting so that the Log is enabled and also “Enabled user access logging” is checked.
After setting this up, and having users do some playback, you can see the user actions in the Audit Log, in the Site Navigation pane you find Server Logs and Audit Log.
