In mid 2009, a fiber optic fence sensor system was installed on McAllen-Miller International Airport's perimeter fence. The system was developed by Future Fibre Technologies and, one year on, the airport's security department reports the system has performed impressively.
“The system was installed in response to security concerns over the number of commercial flights and the airport's proximity to Mexico,” said Donald “Buck” Taft, Airport Security Coordinator at McAllen-Miller International Airport.
“Overall, the system has provided an enhancement to the physical security at McAllen-Miller International Airport,” Taft said. The solution is cost-effective and ideally suited to airport perimeter protection because of its ability to detect the location of intrusions anywhere on the airport's entire perimeter.”
The system consists of a single pass of fiber-optic cable along the fence fabric for the entire protected perimeter. This passive sensor required no maintenance and is completely immune to EMI, RFI and lightning.
The McAllen-Miller International Airport is located in the center of Texas' Rio Grand Valley, close to the US-Mexican border.
“The Rio Grande Valley is located at the southern tip of Texas and is subject to heavy winds, high humidity and hot temperatures,” Taft said. In fact, hurricanes and tropical storms have hit the area three times in the year and a half since the system was installed. “In spite of these extreme weather conditions, the system has operated successfully without nuisance or false alarms.”
“The system features a rain mitigation algorithm that accurately detects the location of an intrusion, regardless of weather conditions,” he said. “The system has transformed the standard chain link fence surrounding the airport into an intelligent sensor that detects intruders automatically.”
