What types of security services are commonly provided by security guards?

The correct answer encompasses a comprehensive range of duties that security guards typically perform in various settings. Security guards are trained to ensure the safety and security of premises, people, and property. This includes patrol duties, which involve monitoring areas to deter and detect suspicious activities. Access control is another essential function, where security personnel manage who enters and exits a facility, thus helping prevent unauthorized access.

Additionally, security guards often monitor surveillance systems, which provides an extra layer of oversight, allowing for quick identification of potential threats or incidents. Responding to incidents is also a critical duty; this means they are expected to take appropriate action during emergencies, such as calling for assistance or managing a crisis until professional help arrives.

In contrast, the other options focus on limited scopes of responsibility. For instance, only assigning patrol duties or solely focusing on incident investigation would not reflect the breadth of skills and responsibilities that a security guard typically has. Therefore, the comprehensive answer accurately represents the variety of services that security guards are trained to provide.
