Name Description
UDP port
The port number used for communication between failover
recording servers. By default, the system uses port 8844.
Database location
Specify the path to the database used by the failover recording
server for storing recordings.
You cannot change the database path while the failover recording
server is taking over from a recording server. The system applies
the changes when the failover recording server is no longer taking
over from a recording server.
Enable this failover server
Clear to disable the failover recording server (selected by default).
Note that you must disable failover recording servers before they
can take over from recording servers.

About failover recording server services
A failover recording server has two services installed:

A Failover Server service, which handles the processes of taking over from the recording
server. This service is always running, and constantly checks the state of relevant recording
servers.

A Failover Recording Server service, which enables the failover recording server to act as a
recording server.
In a failover group setup, this service is only started when required, that is when the regular
failover recording server should take over from the recording server. Starting this service
typically takes a couple of seconds, but may take longer depending on local security settings
and more.
In a hot standby setup, this service is always running, allowing the hot standby server to take
over faster than the regular failover recording server.
