What is a common responsibility of a security guard?

Monitoring surveillance systems is a fundamental responsibility of a security guard. This task involves observing feeds from CCTV cameras and other monitoring devices to keep an eye on activities within a specified area. The goal is to identify any suspicious behavior or potential threats and respond accordingly, ensuring the safety and security of the premises and individuals within that environment.

This responsibility is vital for maintaining security in various settings, such as malls, office buildings, and event venues. Security guards must remain vigilant while monitoring these systems, as they can often be the first line of defense in preventing incidents, deterring criminal activities, and providing rapid responses to emergencies.

The other options involve tasks that fall outside the typical duties of a security guard. Conducting job interviews requires specific HR skills and functions, while personal training sessions focus on fitness and wellness, which are unrelated to security duties. Managing office supplies pertains to administrative responsibilities that are not relevant to security guard activities.
