Which of the following is a proactive measure security guards can take?

Performing regular patrols of the area is a proactive measure because it involves actively observing and assessing the environment before any incidents occur. Regular patrols allow security guards to identify potential issues, deter criminal activity, and ensure that the premises are secure. By being visible and present throughout the area, security personnel can not only respond to incidents more effectively but also prevent them from happening in the first place. This strategy reinforces safety and security by maintaining an ongoing awareness of the surroundings.

In contrast, simply monitoring entrances or waiting for incidents to occur focuses on reactive measures rather than seeking to prevent problems. Being passive, such as only responding to calls for assistance, does not contribute to a proactive security posture, which emphasizes initiative and foresight in managing security risks.
