What best describes the role of surveillance systems in airport security?

The role of surveillance systems in airport security is best described as providing a constant watch over the airport and identifying security risks. Surveillance systems are essential for maintaining safety and security in such high-traffic areas. They allow security personnel to monitor activities in real time, helping to detect and respond to any suspicious behavior or potential threats immediately.

By using high-definition cameras and advanced monitoring technology, these systems can cover vast areas of the airport, including terminals, baggage handling areas, and runways. This comprehensive oversight is critical in preventing criminal activities and ensuring that any security incidents are addressed proactively.

While monitoring passenger flow and optimizing efficiency or enhancing passenger comfort might be additional benefits of modern surveillance technology, the crux of their purpose in an airport security context revolves around risk identification and threat response. Reducing the workload of security personnel could be seen as a secondary effect, but the primary function remains risk management and surveillance.
