What is a common benefit of centralized guard staff monitoring multiple access points?

Centralized guard staff monitoring multiple access points offers significant advantages, particularly in terms of better surveillance and resource efficiency. By centralizing the monitoring tasks, security personnel can effectively oversee multiple entry and exit points from a single location. This enhances the ability to detect and respond to security incidents more promptly and efficiently since the guards have a comprehensive view of all monitored areas.

Additionally, centralization allows for the optimized allocation of security resources. Instead of deploying staff at each access point, which can be costly and can lead to personnel being stretched thin, having a centralized monitoring system can reduce the need for physical presence at every single entry point. This leads to improved operational efficiency, as guards can coordinate their responses based on real-time information from various access points and prioritize their activities based on assessed levels of threat or security breaches.

While the other options might seem plausible, they do not align as closely with the key benefits of central monitoring systems. Increased personnel costs contradict the concept of efficiency, while improved accessibility for visitors and reduced need for physical security policies do not necessarily represent consistent outcomes of centralized monitoring practices.
