What is the main purpose of a security system?

The main purpose of a security system is to keep threats from reaching their targets. Security systems are designed to detect, deter, and respond to potential threats, ensuring the safety of individuals and property. This involves monitoring for unauthorized access, alerting homeowners or authorities in case of an intrusion, and using deterrents such as alarms and surveillance to prevent threats from materializing.

The ability to protect against various threats—such as burglaries, vandalism, and other security breaches—highlights the proactive nature of security systems. Their effectiveness lies not only in their capacity to respond to incidents but also in their role in preventing these situations from happening in the first place.

Other options do not accurately capture this primary objective. For instance, increasing costs for homeowners contradicts the essence of a security system, which aims to provide value and safety. Monitoring employee productivity is a different function that does not align with the essential goal of security systems focused on safety and protection. While preventing all security breaches may sound ideal, it is an unrealistic expectation; no system can guarantee absolute prevention of all incidents, hence focusing on mitigating threats is more aligned with the purpose of security systems.
