Large-Scale Video Surveillance Systems: New Performance Parameters and Metrics

As the threat potential against critical infrastructure increases, more and more flexible, scalable, efficient, reliable and future-proof video surveillance technologies are required. This paper introduces an analytical study of performance parameters for large-scale video surveillance systems. Analog to computer network systems, performance parameters are defined: e.g. reliability, availability (instantaneous, interval and steady state) and survivability are defined, calculated, evaluated and analyzed. Moreover, a new important performance parameter, visual coverage-quality and redundancy levels are introduced. Two case studies are presented, which show that these factors are indispensable for designing the best possible configuration of a large-scale video surveillance systems.
