How are access control points monitored at O'Hare?

Access control points at O'Hare are monitored primarily through security personnel and surveillance systems. This comprehensive approach ensures that both human oversight and technological assistance work together to maintain a secure environment. Security personnel are responsible for actively monitoring the behavior of individuals entering restricted areas, conducting checks, and responding to any suspicious activities. Meanwhile, surveillance systems, such as cameras and alarm systems, provide an additional layer of security by continuously recording and analyzing movements at access points, enabling real-time response to potential security threats.

The combination of these two elements creates an effective monitoring system that enhances the airport's overall security strategy. Other methods, such as employee attendance logs and automated entry systems, while useful in specific contexts, do not provide the robust, real-time monitoring capabilities that human oversight and surveillance technology can offer. Random security checks also play a role in maintaining security but do not constitute a continuous monitoring approach like that of personnel and surveillance.
