Which device is most appropriate for monitoring patrol movements within a building?

The most appropriate device for monitoring patrol movements within a building is an electronic or mechanical checkpoint system. These systems are specifically designed to track and confirm the presence of security personnel at designated points throughout the building. They often involve physical checkpoints where guards must scan badges or use other means to verify their visit, ensuring a reliable record of patrol routes, times, and locations.

The checkpoint system enhances security oversight by allowing for real-time monitoring of patrols and can also provide data for analyzing the effectiveness and thoroughness of security operations. This is crucial in environments that require stringent security measures, as it ensures that every area of the premises is regularly checked.

In contrast, a coordinated lighting system may improve visibility but does not inherently track movement or ensure that patrols are conducted. A floor plan and compass provide navigation assistance but do not monitor movements. A managed hallway directional system could assist in directing personnel but lacks the necessary tracking feature inherent to a checkpoint system. Therefore, for the specific purpose of monitoring patrol movements, the checkpoint system stands out as the most effective and relevant option.
