I’ve been thinking about buying a security system for a while now, but I don’t know that much about them. How do they work?
A security system starts with a control panel. Usually located in a closet or a basement, the control panel contains the “brains” of the security system, and essentially operates as a central computer. Various sensors connect to the control panel from locations throughout your home. If your security system is armed and the sensors detect a problem, they send signals to the control panel. The control panel automatically dials the central monitoring station, where the proper authorities are notified.
