Which of the following is a key responsibility of a security guard?

A key responsibility of a security guard is to patrol and monitor the premises for suspicious activity. This role involves observing the environment, identifying any unusual or potentially threatening behavior, and ensuring the safety and security of both the property and the people within the area. Regular patrolling helps deter criminal activity, and responsive monitoring enables security personnel to react promptly to incidents, thereby maintaining a secure environment.

The focus of a security guard's duties is primarily on prevention and observation rather than enforcement actions such as making arrests, which is typically the responsibility of law enforcement agencies. Security guards do not act as primary law enforcement; rather, they support local authorities and report incidents when necessary. Additionally, conducting financial transactions is not a standard function of a security guard and falls outside the realm of their responsibilities of ensuring safety and security.
