底特律韦恩州立大学的停车场智能监控系统(英文)
"Smart" CCTV at Motown's Wayne State University

对于大学来说，停车场已逐渐成为吸引和留住学生尤其是来进行再教育的上班族和成年人的必要设施，甚至学校的公共场地和绿地也时常被侵占为停车位。另外，建在市区的校园，没有地方扩建停车场，只能向上发展建造停车库，以适应人们每天成百上千的停车需求。对于大学校园的停车设施经理来说的另一个挑战是，还需要在停车便利性和停车场入口和开放程度的安全性方面找到一个平衡点。安全是安装智能监控系统的目标之一，每个人都认同安全的重要性，但是对于应该做什么、花费多少钱，大家的观点就有很大的差异。本文把风险和弱点评估放在了一个重要位置上，籍此决定应该选择哪种安全措施和技术以提供最大的利益。

The "intelligent" part of the system is the key. Unlike other systems that must be watched virtually every moment, the WSU system monitors 14 specific types of activity and behavior, and only then generates alerts based on user-defined rules. For example, it looks for someone lurking-a potential criminal who may case cars to steal property, or even assault or rob parking patrons. So, when the system detects a person who parks and remains behind or who has entered the garage on foot and is standing or walking between cars, it alerts the person on duty. Other behaviors that are notable in a parking garage, such as a falling person, two or more people converging on foot, or a vehicle moving at excessive speed or stopping suddenly are noted and displayed as "events." The idea, according to Frederick, is "we don't need and sure don't want to see everything, all the time, and we can't afford to tie up numerous staff people to stare at monitors."
