A security installation for a property includes an imperforate protective barrier, a plurality of spaced posts extending upwardly from the top of the barrier and a plurality of spaced trip wires extending between the posts for detecting the presence of an intruder breaching, or attempting to breach, the barrier. The installation further includes a plurality of spaced posts protruding transversely from the inner side of the barrier, and a plurality of electrical wires extending between the posts. The electrical wires are adapted to impart at least a temporarily incapacitating shock to an intruder. |
