ABSTRACT
Servers and storage are important components of a network video system as they are used for monitoring, recording, managing, and archiving video. A major benefit of IP-based video surveillance is the ability to deploy standard server and storage components from the IT world. Components can range from a low-price desktop PC to a blade server system attached to a storage area network (SAN) with petabytes of storage that can cost millions of dollars. As they are easy to use and install, purpose-built network video recorders (NVRs) are popular in small and some midsize systems, especially if the NVRs have built in PoE ports to power the cameras. Some of those NVRs are proprietary in nature and are not based on standard servers and components.
