Electromagnetic Detection

Most intrusion detection systems in use today utilize some form of electrical circuit running through wires, mechanisms, metalized tape or foil. If any part of the electric circuit running through two pieces of metal in the door locks or window lock mechanisms , or if a strip of metallic tape on the window glass is broken, it trips an alarm.

Circuits work well when an intruder attempts entry as one would expect, by opening a door or window. Burglars however, know how to use crowbars and other burglary tools to get through doors without disrupting these electrical circuits. In warm climate regions, houses may have thin walls, and entry can be gained by cutting through a wall. Tape or wire mesh in the wall would have to be torn or cut through to gain entry, thus tripping the security alarms .
