The Administration and Monitoring with Failover Module transfers video streams from a failed ISP
to a failover ISP. If only one video channel fails to record, the system switches only that video
stream to the failover ISP
Figure 40 shows how, after a failure event, available ports on the failover ISP become active and
begin recording traffic that was originally destined to a failed ISP.

Failover ISP recording
If a failure occurs, the Administration and Monitoring with Failover Module updates the history log
with event details. To view the log, choose History > View Log... or press F5. Figure 41 shows an
example in which five cameras have been successfully redirected to the failover ISP.
