How does surveillance enhance airport security measures?

Surveillance enhances airport security measures primarily by allowing for monitoring and recording activities in real-time. This capability provides security personnel with the ability to observe various areas within the airport, detect unusual or suspicious behavior, and respond rapidly to incidents as they unfold. Real-time monitoring helps in identifying potential threats or emergencies, thereby increasing the responsiveness and effectiveness of security efforts.

Additionally, recorded footage serves as invaluable evidence for investigations following any incidents, enhancing overall safety and security protocols at the airport. This robust monitoring system contributes to creating a safer environment for both passengers and staff, ultimately bolstering the overall security framework of the airport.

Other options do not accurately capture the essential benefits of surveillance in airport security. For instance, while surveillance may optimize personnel allocation, it does not completely eliminate the need for human oversight or presence. Additionally, surveillance does not replace the necessity for screening processes that ensure passenger safety, nor does it discourage the usage of the airport—its goal is to enhance safety and vigilance, not deter customers.
