What is the main function of a security alarm system?

The main function of a security alarm system centers on its ability to detect unauthorized access or threats to a property. This includes identifying intruders who may attempt to enter a facility without permission and recognizing potential threats such as break-ins, vandalism, or other security breaches. The core purpose of the alarm system is to monitor the environment for any signs of intrusion or danger, triggering alerts to notify occupants or security personnel when an anomaly occurs.

When unauthorized access is detected, the system typically activates an alarm to alert those within the vicinity and may also send signals to a monitoring service for a rapid response. This emphasis on detection makes it the primary purpose of the system, as it is designed to provide property owners with peace of mind and a proactive means of safeguarding their premises against threats. While video surveillance, access control, and notifications to emergency services may complement a security system, they are not its main function.
