Airport security system has evolved considerably, and there is a lot more than a passport control and metal detectors to help with the security and safety of passengers. Because of the high-profile criminal and terrorist activities in some airports, airport security has seen some remarkable advances in technology to enhance the safety and security of passengers, staff, and the airport. Traditionally, all passengers had to be treated the same, as if they were criminals, illegal aliens or terrorists which meant that they were all under suspicion. New technology and systems means that airport security only needs to focus on those people who are acting suspiciously, rather than all passengers.
Although CCTV has made airport security much more efficient, there is still a need for people to be constantly looking at the CCTV footage, and recognising what is going on. For the person monitoring the CCTV footage, a moment of distraction, or looking at another incident, could prove to be costly.
Using advanced Video Analytics, the CCTV footage can be analyzed by computer software, to assess what is actually taking place on the screen. This means that situations can be identified, and rules can be set up, so that any event triggering these rules will alert security staff. For example, somebody who leaves a bag near unattended, or who is in the wrong part of the airport, or walking around the perimeter. Crowd detection technology allows individuals to be tracked and traced through the airport. The footage can be tagged and is searchable, so that the person, or event that triggered the rules can be found, and analyzed. People who are where they shouldn't be, looking generally suspicious, loitering, or people passing items between themselves can also be monitored.
