alarm systems for homes
Next, decide what kind of control panel you want. There are two types: A “cabinet style” panel consists of a keyboard that mounts near the door and a circuit board that mounts near your phone interface. A “self contained” panel is a single unit that mounts near the door. This one part panel is easier to install but has one weakness. An intruder entering through the door can tear it off the wall before the panel finishes notifying the monitoring service. With a two part panel, the circuit board keeps working even if the keypad is disconnected.
