Perimeter Security

having worked in correctional healthcare prior to my current line of work, i may have something to offer along those lines...

Razor wire, of course is an effective obstacle.  however, it can be unsightly and / or annoying to the neighbors. 

one possibility is the so-called "taut wire sensor"

this system uses a fence constructed of wires under a specific, known tension running parralel to the ground and spaced approx 4 inches apart.  if a person tries to climb the fence, they have to use these wires as "rungs on a ladder." increasing (or decreasing by cutting the wire) by a preset amount triggers an alarm.  the preset amount is adjustable to allow compensation for things like birds landing, high winds, raccoons etc.
