The airport integrated data from the City of Tallahassee 's geospatial information department to incorporate data on the location of fire hydrants, gas lines, and water lines to assist first responders. A geospatial information system was the integration point for all alarms and interface to the security personnel. The project demonstrated the ability to build on these sub-systems through a wireless mesh communications network to dramatically improve the ability of security and emergency personnel to understand and respond to threats and emergencies via their PDAs.
Interviews were conducted with airport, local law enforcement, and TSA staff to observe the airport in operation. Following this stage, in order to achieve the design objectives, it was necessary to securely expand the airport's LAN to the outer perimeter to enable new sensor installation. The objective of this task was to effectively detect all intrusion attempts while minimizing the occurrence of false alarms. The system software looks at multiple sensor system inputs to determine if alarms are real.
The design and development of a highly usable interface contribute significantly to the operational utility of RAPIN. Complex information was presented in a form that could be easily comprehended, unambiguously understood, and organized to quickly draw the operator's attention to the most important factors.
Extending the LAN to the entire AOA also provided the ability to install access points for WiFi communication to roaming first responders. Together, the extended LAN, sensors, system software and common operational picture function provided the backbone for demonstrating the project goals and succeeded in creating the test-bed for expansion and future development.
Getting the Most out of Intelligent Video
The site survey included a detailed review to determine sensitive security requirements and how best to use intelligent video analytics to increase security awareness. Nineteen CCTV cameras running Vidient SmartCatch from Vidient Systems Inc. were installed. These cameras can detect numerous suspicious behaviors, including human and vehicle tailgating, unattended objects, loitering and perimeter breaches. The cameras sense and identify people, vehicles, and aircraft in both the general aviation and terminal areas, and alerts are produced both visually and audibly. The identification data is successfully made available through a data stream captured by the GIS interface.
The video processing power and the intelligent video viewer were installed in the SOC to provide security personnel with direct access to security alerts. The intelligent video was also integrated with the Geo-COP system to allow security personnel to easily access security alerts and other pertinent information in one GUI.
“By bringing processing power directly to the edge, we are taking intelligent video solutions to the next level,” said Brooks McChesney, Founder and Executive Vice President of Vidient. “Networked video analytics are the pulse of the security system and we have made them more scalable and interoperable than ever. These IV solutions run seamlessly without disrupting network performance.”
Protecting the Perimeter
The location-sensing intrusion detection system uses a fence-mounted fiber-optic vibration sensor to detect and pinpoint attempts to climb over or cut through the airport's perimeter fences. The system reports alarms and breach locations to a local or remote alarm management station, which can use this information to point security cameras at the reported location and to notify security personnel. A single sensor can monitor the entire fence line of a typical airport, while requiring no power or communication infrastructure in the field.
A solar-powered PTZ camera is located at the midpoint of the installation and can be used to validate alarm and track intruders. The camera is an IP camera connected to a mesh radio so no wiring or power from the facility is required. This functionality demonstrates a typical installation requirement for general aviation or remote locations of controlled airports where power and communications would be difficult to install.
The perimeter fence detection system has demonstrated close to 100-percent probability of detection of fence climbing and typical location accuracy of 20 feet or better. The system has further demonstrated an average total alarm rate of less than one alarm per day showing low correlation with environmental conditions (wind, etc.) — thus, nuisance alarm rates remain low.
