MANAGING AIRPORTS TODAY May 2015 airportbusiness 39 the complete picture needed to accurately assess the situation. For example, thermal imaging cameras or radar can indicate if something is at the perimeter, but don't identify what or who that something is. Similarly, a fence shake detector can be helpful, but when the system sounds the alarm it doesn't provide insight into what's causing the shaking. Cameras with video ana- lytics can also be effective, but there's no way to completely eliminate false alarms. A MULTIFACETED APPROACH Perimeter protection requires a multi-lay- ered approach, including a Physical Security Information Management (PSIM) technology that can correlate incoming information from vari- ous perimeter intrusion detection systems and provide a higher level of situational awareness. For example, how can airport security determine whether an alarm from a fence shake detector is a gust of wind or something more serious? PSIM combines the fence shake alert with a video ana- lytics alert so airport security can have a high level of confidence that a perimeter intrusion is real. And, the PSIM system can put information together in real time, so security staff can be appropriately alerted and respond accordingly. Miami International Airport has taken an innovative, multi-layered approach to perimeter security and combined its existing technolo - gies, such as tower radar, video management, and video cameras, with newly purchased ground radar, vehicle GPS tracking, and various low light/fixed thermal/PTZ tracking cameras. A PSIM solution pulls information from all of these sensors together and provides analytic and visualization capabilities that help security more accurately identify, locate, and confirm unidentified targets that could pose a threat. This approach also allows the airport to lever- age its existing investments in security tech- nology more effectively by integrating siloed systems into a cohesive solution. Airports can take this a step further with new video analytics applications, such as NICE Suspect Search, that allow security staff to track down an intruder once a perimeter breach has been detect- ed. Suspect Search integrates with video surveillance, including PTZ cameras, and PSIM. Using an image captured from a video camera or a user-generated avatar, the applica- tion automatically searches through video across all of an airport's sur- veillance cameras and displays possible matches of the intruder in seconds. Once the intruder has been identified, his or her movements are recreated on a map so airport securi- ty personnel can visualize the intrud- er's route and last known location. Just because the impacts of perimeter security breaches to date haven't been widespread or catastrophic doesn't mean perim- eter security should be put on the back-burner. Airports must take a multi-layered, proactive approach to perimeter protection. Fortunately, the technologies exist to make security efficient, and even cost-ef- fective, with the ability to leverage existing systems.
