When moving configuration to the Backup Server and getting it back to the Main Server the Failover service object generates START and STOP events. These events can be used in scripts for flexible system configuration. For examples see Examples of scripts in JScript language section of Programming Guide (JScript).

In this case the system gives 2 months to restore the faulty Server in order to move the cameras back and the license to become valid again.

Time (in days) remaining for restoring the main Server is shown on the settings panel of the Failover service object:

When you log off INTELLECT™, configuration is not transferred from main Server to a standby server.
