Which of the following is a common duty of unarmed security personnel?

Monitoring surveillance equipment is indeed a common duty of unarmed security personnel. This responsibility involves observing live feeds from security cameras to identify any unusual behavior or potential security threats. By actively monitoring these feeds, security personnel can respond promptly to incidents, assist in deterring criminal activity, and ensure the safety of the premises. This role is critical in maintaining a secure environment, as well as providing evidence in case of incidents.

In contrast, conducting investigations, managing staff schedules, and performing maintenance checks are not typically primary duties associated with unarmed security personnel. Investigations are generally carried out by law enforcement or specialized security teams, while managing staff schedules and performing maintenance checks typically fall under the purview of administrative or facility management roles. Thus, the focus of unarmed security personnel lies primarily on surveillance and direct monitoring to safeguard the environment effectively.
