What are common types of security systems?

The correct answer focuses on the commonly utilized components of security systems that are integral to maintaining safety and monitoring environments. CCTV (Closed-Circuit Television) serves as a surveillance tool that allows security personnel and management to monitor activity in real-time and review footage for investigations. Alarm systems are designed to detect unauthorized entry or breaches, alerting security and law enforcement to potential threats. Access control systems manage who can enter specific areas, ensuring that only authorized personnel are allowed access to sensitive locations, thus enhancing overall security.

While other choices mention important security concepts, they do not reflect the specific types of security systems that are widely recognized in the field of security management. Patrol services, personal defense tactics, and community awareness programs are valuable components of a comprehensive security strategy, but they are not classified under the technical systems that are typically installed for surveillance and access control. Recognizing the importance and functionality of CCTV, alarm systems, and access control systems provides a solid foundation for understanding how to implement effective security protocols.
