Distributed acoustic sensing for airport security

on March 25, 2019

PlaneThe perimeter security is considered to be a significant problem to airports all over the world. For example, Denver International Airport is one of the largest airports in the USA that includes 25 airlines. Its size requires constant security operations, and it is highly challenging because the larger an airport’s size is, the bigger its perimeter, the more difficult it becomes to save integrity and police borders.

The ways for airport border security include walls, barbed-wire fencing, CCTV, guardhouses and manned patrols. Of course, the mentioned measures are effective, however, they are mostly passive barriers that are possible to cross. Thus, the use of modern technologies such as artificial intelligence and distributed acoustic sensing or DAS system allows improving the situation with the management and security of airports.

DAS technologies offer continuous monitoring of the whole perimeter and have alerts in real-time, provide security groups the complete overview that is required for operational management, and respond to threats effectively. Moreover, DAS systems have many benefits for airport operators, when it comes to the adoption of digital technologies, their integration into perimeter security strategies.

The principle of DAS operation is based on the use of fiber optic cables that are similar to an ecosystem of highly-sensitive, vibrational sensors that creates a smart barrier around the whole perimeter. Herewith, it is possible to install a distributed acoustic sensing system both in the ground and established into fencing.

Also, it should be noted that DAS is a highly reliable technology because it continues its operation even after it has been cut. DAS system has the following advantages for the airport area:

  • The ability to identify and locate such potentially threatening activities as walking people, excavation and tunneling processes, fence climbing and cutting.
  • Distributed acoustic sensing allows collecting data on prolonged or historical events.
  • DAS technology highlights long term patterns and points of potential vulnerability.
  • DAS offers a clear differentiation between numerous threats that might occur at the edge of an airport, herein, the technology provides security teams special alarms that enable to make decisions quickly.

Finally, DAS monitoring is the ideal solution for airport security because there are the earliest alerts for security groups. Moreover, airport operators can combine distributed acoustic sensing with other traditional techniques.

Optromix is a DAS system manufacturer that provides top of the line distributed acoustic sensing systems suitable for monitoring of commerce networks. If you have any questions or would like to buy a DAS system, please contact us at info@optromix.com
