Since closed circuit television monitoring (CCTV) was introduced in the early 1960’s, the video surveillance market and its supporting technology have been continually evolving. Over the past two decades, hundreds of millions of CCTV cameras and video management systems (VMS) have been deployed worldwide; serving a wide range of markets from small retail outlets to citywide public safety solutions.
Most recently, the video surveillance market has been heavily influenced by the rapid evolution of IP networks. This has led to a transition from analog CCTV video systems to more sophisticated, proactive, network-based IP video solutions. The transition from passive analog systems to network-based intelligent video solutions has greatly improved the ability to quickly and efficiently respond to unfolding events, and distribute video data across organizations and to external agencies. Furthermore, with network-based intelligent video solution’s added functionality and intelligent capabilities, the extraction of valuable operational insights — beyond security and safety — is now possible.
The transition to IP also reflects the market’s desire to treat video like any other network data asset. By integrating video with other types of network-based systems such as building management and corporate data systems, organizations can create a more holistic security solution.
With analog cameras having an average lifespan ranging from 10 to 20 years, and shipments of approximately 20M units annually in recent years, it is assumed that worldwide the install base of analog cameras is approximately 200M units. From these numbers, it can be further assumed that a significant number of organizations that are purchasing surveillance systems today already have analog cameras and cabling deployed.
Such organizations face a dilemma – how to make the most of their analog assets today while planning for a smooth migration path to IP video tomorrow. This is exactly the question we address in this application note titled “Maximizing your video assets.”
