The surveillance market is splitting into two primary types of systems; DVR – primarily analog systems that have cameras directly connected to the system, and NVR – digital systems that have cameras connected via IP (internet protocol). Due to the fact that DVRs have a finite number of cameras that can be physically attached, the number of streams and maximum workload on the hard drives can be determined. Since NVRs theoretically can have an unlimited number of cameras attached to the system, the number of streams, workload on the hard drive, and the system’s retention period can scale beyond that of a DVR.
