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.
Claims18
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.
A supporting post in a taut wire intrusion detection system, said post comprising:
- at least one sensor to monitor the tension of at least one taut wire attached to the sensor;
- and
- at least one anchor element to maintain a taut wire segment in tension.
Method of improving the consistency of detection in a taut wire fence system, the method comprising:
- providing at least one anchoring element and at least one sensor on the supporting posts of the taut wire system wherein the overall sensitivity of the system varies on a range that is smaller than that of a system with separate sensor posts and anchor posts.
A method of identifying the location of an intrusion attempt, the method comprising:
- providing at least one sensor on at least two supporting posts of a taut wire system, said supporting posts communicating an alarm condition in response to a change in said sensor state;
- and
- determining the location of an intrusion attempt by identifying the area between adjacent supporting posts, when both supporting posts communicate an alarm condition.
A taut wire fence section, the section comprising:
- a first anchor post that includes anchor elements to hold taut wires in tension;
- at least two supporting posts that include both sensors that are attached to taut wires to monitor the tension thereof and anchor elements to hold taut wires in tension;
- a plurality of taut wires maintained in tension between anchor elements;
- and
- a second anchor post that includes anchor elements to hold taut wires in tension.
