"Magnetic anomaly detectors. You bury special transmitting cables beneath the ground, outside the perimeter, so that they build an invisible electromagnetic field around and above their location. Anything—doesn't even have to be metal—that enters the field will distort it. If you go with the Sentrax system, made by an outfit in Switzerland called Cerberus, you can have the whole thing linked to a central console that displays the layout of the perimeter on computer screens."
