how do Wireless Alarm Systems work?
Each contact (door, window or screen) is wired to a little box that wirelessly sends its contact state to the alarm box.
The system allows you to skip running wires from every contact to a central location where the alarm box is.
The down side is that you will often see the transmitter boxes near the window or door.
