Airport Perimeter Security: Where we´ve been, Where we are, and Where we´re going

Perimeter security at an airport requires disparate sensors to operate in concert to detect intruders; track them; assess threats; coordinate responses; (for example, human responders for investigation, or door and gate closings); gather evidence for law enforcement prosecution; and coordinate responses between law enforcement agencies. At present, no one system accomplishes all these tasks. Our work and development has evolved a system that meets these needs. In this paper we describe that evolution and show where we´ve been in system development, how that past has shaped our present deployment of systems and how our current work will lead to a complete solution.
