How do I make a trip wire? Answered

How do I make a trip wire? Additionally, how do i set up the trip wire to alert me from a remote location so that the intruder will not be alerted but I will

Figure out some way to make hitting the wire close or open a switch; connect that to wires and/or transmitter, as appropriate, to transfer that signal to the remote location.

Most "trip wires" are pretty noticable. If you really don't want to alert the intruder, I'd go with motion detector or photocell or pressure mat or something of that sort which doesn't present any tactile evidence of its presence.
