The ideal perimeter security solution for airports

Airports are vital components of a country's economy nowadays where it transports high-value cargo but also contributes to the ever-growing tourism industry. In the last decade, there have been increased measures to increase security around perimeters of airports as criminals got smarter in their approach to cross existing perimeter security. In order to increase perimeter protection around airports, many kilometers of fencing has been deployed where security cameras, microwave detection, and other perimeter intrusion detection systems have been used to signal security personnel in case of an intrusion. Although, detection systems have become smarter over years they still cope with difficulties such as false alarms and high maintenance and installation cost. Furthermore, an alarm should be directly communicated not only to the airport security reaction team but also to the Transportation Security Administration (TSA) who are responsible for screening passengers and baggage. Ultimately, airports would like to have a solution capable of neglecting false alarms but providing ultimate detection capability for when a serious intrusion does occur.

Perimeter security requirements by airports

  • Intrusion detection systems that directly communicates with the TSA and airport reaction team.
  • Minimize false alarms but provide intelligent detection capability to detect threats.
  • Low installation and maintenance cost.

Sensurity sought to cover these requirements by introducing its advanced microwave intrusion detection systems. Not only do these systems (HALO/VIGIL) provide ample integration options with existing security infrastructure, but they also do provide intelligent detection as a result of its own patented software analytics and algorithms. In this way, HALO and VIGIL are capable of filtering out irrelevant intrusions from small animals, vehicles, or debris and can tweak its algorithm to only alarm in case of a serious human intrusion.

The problem

The Catania Airport had existing perimeter security in place, encompassing a metal perimeter fence and active infra-red towers to protect the emergency exit gates of the airport. However, the airport was coping with a high rate of false alarms from the IR towers as a result of interference from the metal fence and long grass growing along the perimeter. This resulted in high maintenance requirements around the perimeter where security personnel was falsely informed on several occasions.

Project requirements

Therefore, the airport was in need of robust perimeter intrusion detection systems that would eradicate the problems that occurred with previous detection systems. Moreover, the solution was to communicate directly with the airport security reaction team so immediate action could be taken by security personnel and police.

Our approach

First of all, Sensurity's microwave intrusion detection systems were proposed by the perimeter maintenance contractor, Free Sat Srl, where a trial installation was put in place. After vigorously testing the systems, it proved to meet all the operating requirements of the customers whereafter an order was placed. From that moment, Free Sat Srl and Sensurity worked closely together to install the systems and provide ongoing technical support to foresee customer satisfaction.

Solution for the client

So, the final solution encompassed Sensurity's HALO microwave intrusion detection systems that protected the perimeter of the airport with a long tall 'virtual wall' that reached 200 meters in length and 10 meters in height per set of units. In addition, the systems are capable of accurately differentiating intrusion types and provide 24/7 detection throughout the day.

The Result

After the successful installation of the systems, the solution has appeared reliable where a minimum amount of false alarms have occurred and where 100% positive detection have taken place. On top of that, the systems do regularly get tested by airport authorities where they have expressed strong satisfaction towards the detection capability of our units.
