Abstract
A taut wire intrusion detection system includes posts that are used to detect an intrusion into a secured area. The supporting posts are used to both detect a movement of the taut wire and anchor the taut wire by using separate anchor and sensor elements. The taut wire system eliminates many of the weaknesses of prior taut wire systems by providing a less variant taut wire sensitivity.
Claims13
A taut wire intrusion detection system, comprising:
- a first support post which comprises at least one taut wire anchor element and at least one taut wire sensor;
- a second support post which comprises at least one taut wire anchor element and at least one taut wire sensor;
- a first taut wire segment which extends under tension between the first and second support posts, the first wire segment being anchored to the first supporting post by an anchor element thereof and being coupled to a taut wire sensor of the second support post;
- and
- a second taut wire segment which extends under tension between the first and second support posts such that the first and second taut wire segments are vertically separated from one another, the second taut wire segment being anchored to the second supporting post by an anchor element thereof and being coupled to a taut wire sensor of the first support post.
