How Alarm Systems Work

There are three basic components of a security system: the controls, the sensors, and the monitoring center.

Security sensors are positioned around the home to detect signs of trouble. Some types of sensors detect when a door or window is opened, while others sense things like smoke, water, and carbon monoxide.

The controls manage the system, communicating with both the sensors and the monitoring center. Homeowners can use the controls to arm and disarm the system and gain information about all security-related activity.

If a sensor in the home detects trouble, it signals an alert to the control unit, which signals the monitoring center. The monitoring team will then contact the homeowner and dispatch the appropriate local authorities.

Systems with interactive features provide 24/7 access and control, regardless of a homeowner’s location. Any internet-connected device can be used to remotely arm, disarm, and monitor all activity. Video monitoring is another highly interactive option available with some modern alarm systems. Video offers an extra layer of security and a great way to stay connected to kids and pets.

The intelligence built into today’s home security systems also allows homeowners to control a variety of devices within the home, such as lights, the thermostat, and door locks. Home automation saves time and money, and it also helps to conserve energy and enhance security.
