Design Guide

A simple way to verify that video streams are being recorded to the failover ISP is to select

playback keyboard functions, such as instant replay or time/date search, while in failover mode.

The failover ISP continues to record until the failed ISP recovers. At that time, the Stream Manager

Administration and Monitoring with Failover Module polls the recovered ISP three times before

switching back to the primary ISP and returning the failover ISP to standby mode. Figure 42 shows

a history log that indicates that the failover ISP has stopped recording the failed video streams.
