Which component provides flexible options for storing video and audio using a combination of network- attached storage, direct-attached storage, and SAN storage deployments?

The Cisco Video Surveillance Media Server handles video stream ingestion and playback management, not the flexible storage architecture across NAS, DAS, and SAN.

The Virtual Matrix Software is a display and video switching solution, not a storage system.

The Cisco Video Surveillance Storage System is specifically architected to integrate NAS, DAS, and SAN storage tiers, giving operators flexibility to scale and mix storage technologies within a single surveillance deployment. Its design abstracts the underlying storage medium from the video management layer, enabling hybrid storage strategies.

The Transcoding and Encoding Server converts video formats and bitrates but does not manage physical storage deployments.

The ISR Video Management and Storage Module is a single-appliance module integrated into ISR routers for local recording, and does not support the NAS, DAS, and SAN combination model.
