Which Cisco Video Surveillance device is responsible for providing video streams to monitors after the respective layouts and views are received by the monitors?

The Cisco IP Video Surveillance Operations Manager is an administrative and policy management platform that handles device configuration and event management, not video stream delivery.

The Cisco IP Video Surveillance Virtual Matrix Viewer is a display client that receives and renders streams on screen; it consumes streams rather than providing them to other monitors.

The Cisco Video Surveillance Manager is the broader system management platform handling device onboarding, recording policies, and user management, not the direct source of video streams to monitors.

The Cisco Video Surveillance Media Server receives video from IP cameras, performs encoding and transcoding as needed, and then delivers the resulting video streams to clients such as the Virtual Matrix Viewer or other monitors - making it the definitive source of video stream distribution within the Cisco Video Surveillance architecture.
