Throughout 2007 and 2008, intelligent video systems have seen substantial growth. There have been adoptions of intelligent video systems in many critical  infrastructure industries including ports, airports, power plants, large infrastructure projects etc.

This has also made huge impact in the large infrastructure security markets. An integrated and intelligent security platform can provide safety and security, reduce cost  on security spending such as personal and hardware, help users manage their sites more efficiently and improve operational efficiencies at their sites.

The need for security has also driven the development of video analytics market. According to IMS research, the market for video analytics will grow to US$807.7 million in 2012 at annual growth rate (CAGR) of 69.3 per cent. This article intends to looks at the challenges of video surveillance and how intelligent video systems help combat those problems.

Challenge facing traditional surveillance

Video surveillance has gone through continuous evolution over the past 20 years. The surveillance technology has gone from bulky video tapes to digital networked systems, which can capture video contents and store them directly to a PC hard-drive. During the process, functionalities and performances have been greatly enhanced. However, security and practicality of the systems are still limited due to certain constraints including:

1) Security personal can be distracted or inattentive while watching CCTV monitors. Research has shown that after approximately 12 minutes of continuous viewing of two or more sequencing monitors, operators can miss up to 45 per cent of scene activity. After 22 minutes, operators miss up to 95 per cent of scene activity.

2) Cost of true 24/7 operations can increase if the system is not properly utilised. Need to employ more guards to cover critical areas.

3) Reactive incident response. Currently, most traditional surveillance systems can only serve as monitoring and recording systems. They record video content and store them in DVRs. When accidents or a security breach take place, the recorded videos are reviewed for forensic purpose only. Therefore, the systems are not utilised to prevent security breaches.

4) Long reaction time, low systems utilisation rate, inconsistent policy enforcement etc.
