Step 4: Cisco Stream Manager Modules
Figure 11 shows a complete hybrid system integrating with a matrix switch to provide playback
functionality. The system can easily scale to support thousands of cameras and allows operators to
use other Stream Manager utilities for added functionality.
While the hybrid solution can work without the Cisco Stream Manager Client Viewing Module, this
Windows-based software provides a flexible way to view streams from any network location. In
addition, the software allows exporting video streams to a video file for review.
The Cisco Stream Manager Administration and Monitoring with Failover Module provides system
health information and alarm capabilities for all Cisco Video Surveillance devices in the network.
This module is required in a failover environment, as explained in the next chapter.

Hybrid Design Solution
Viewing Live and Recorded Video
When an operator presses a key sequence on the keyboard to retrieve recorded video, the ISP,
data converter, and hybrid decoder provide the functionality to identify the request and display the
video on the appropriate monitor.
Live Viewing Operation
For live viewing operations, the ISP monitors for special key sequences that indicate a request for
video playback. If no playback requests are received, the Stream Manager software that is running
on the ISP sends the serial commands back to the matrix switch. This step typically takes less than
one second and an operator does not notice any delay when switching video streams on the matrix
switch.
