Visitors must pass through an entry vestibule, check in at the office, and be buzzed electronically through a second set of doors. Metal detectors can be incorporated into the first set of doors, alerting school staff when more careful examination of visitors is necessary. Natural surveillance firmly encompasses the area outside the main entrance, including parking lots, pick up and drop off areas, the main entry vestibule itself, the primary exit and the school hallways. Access control is in place, and the assertive placement of the main office reinforces territoriality. Lowest security level.
Office is hidden inside building.
No surveillance to outside. Little or no surveillance inside. No access control. Visitors who respond to signs directing them to office have permission to roam through entire building while seeking the office. Office is located along main hallway.
