“
...the efficacy of CCTV comes down to two major issues: the cost of manpower and the limitations of staff...”
§ Affordable? We are still talking about millions of dollars and airports insist on a return on investment. So when making decisions about this kind of expenditure, there has to be a strong business case. This does not mean that security concerns do not have a business case; failure to adhere to mandatory procedures can result
in
fines, unnecessary evacuations can cost small fortunes and poor facilitation can mean lost earnings in the retail outlets.
§ The evidence is that most airports make facilitation the priority with security concerns coming second. Fortunately, the main cost of a CCTV system is the network infrastructure so that it is not necessarily prohibitively expensive to use the system to address security issues as well.
Many areas of an airport require surveillance, responding to its own unique security challenges: aircraft and apron security, perimeter integrity, vehicles entering airport zones, arrival/departure areas, immigration and customs control areas, security checkpoints and baggage handling areas.

ANALYTIC TECHNOLOGIES
While some may have reservations, many video analytic technologies are fairly mature and already in use whilst others are undergoing trials.
Each of these areas has a CCTV solution but before specifying them, it is important to mention that the proper use of CCTV (or any other) technology does not only get the job done with fewer people, it also leads to a level of security that just would not be possible using people alone. A simple example will illustrate this point. Security patrols are an important component of any security programme but a security guard checking staircases once a day is no match for cameras pointed at every door, monitoring activity 24 hours a day.
Line crossing an alarm is triggered when there is movement across a ‘virtual line’. This can be used in perimeter intrusion detection solutions. Another application would be for monitoring unattended aircraft – once the aircraft is parked, a circle can be ‘drawn’ around it so that any approach generates an alarm indication.
Automatic Number Plate Recognition (ANPR) is used for traffic management and also for intelligence gathering purposes. In an aviation
context, ANPR can assist with identifying suspicious or stolen vehicles approaching the airport.
