Which of the following is a crucial duty of a security guard?

Monitoring security systems is a crucial duty of a security guard because it directly relates to maintaining the safety and security of the area or property they are assigned to protect. Security guards are often responsible for observing surveillance footage, monitoring alarms, and checking access control systems to ensure that no unauthorized individuals enter the premises. Their vigilance in monitoring these systems allows them to detect potential security breaches or emergencies early, enabling them to respond promptly and effectively.

In the context of security operations, while customer satisfaction and the provision of technical support are important aspects of certain roles within a business or organization, they do not typically fall under the primary responsibilities of a security guard. Additionally, designing security policies is generally the responsibility of security managers or planners rather than the guards themselves. Their primary focus remains on the active monitoring and immediate response to any incidents that may threaten safety and security.
