1. An intrusion detection fence of a taut wires type comprising:
- two anchoring poles that are positioned at a distance from one another;
a plurality of wires that are stretched taut between said two anchoring poles;
at least one sensors'"'"' pole that is located between two said anchoring poles; and
at least one sensor that is installed on said at least one sensors'"'"' pole, wherein said at least one sensor is linked with at least one of said plurality of wires for sensing phenomena that accompany an attempted intrusion through said fence;
wherein said intrusion detection fence is characterized by that;
said at least one sensor is a multi-axis accelerometer that is installed on said at least one sensors'"'"' pole and connected to said at least one of said plurality of wires via a movement converting means, which from an instant of loading said at least one of said plurality of wires as happens when an intrusion attempt through it occurs, converts a movement of said at least one of said plurality of wires to a movement of said at least one sensor that is amenable to be sensed by at least two axes of the multi-axis accelerometer.

Abstract
A sensor for an intrusion detection fence of a taut wires type and a method implemented in its operation, wherein the sensor is a multi-axes accelerometer that is installed on the sensors'"'"' pole of the fence while inclined relative to the fence taut wire unto which it is connected, and the sensor is connected to fence taut wire via a movement converting means such that from an instant of loading the taut wire as happens when an intrusion attempt through it occurs, the movement converting means converts the movement of the taut wire unto a rotational movement of the sensor that is amenable to be sensed in at least two axes.

8. A sensing assembly with a tri-axis accelerometer type sensor, to be used as a sensor in an intrusion detection fence of the taut wires type comprising:
-
base means for installing said assembly on a sensors'"'"' pole of said fence in a manner so that said tri-axis accelerometer would be installed wherein it is inclined relative to a taut wire to which it is allocated; and movement converting means, which from an instant that said taut wire is loaded as happens on occurrence of an intrusion attempt through it, converts the movement of said wire to a rotational movement of the tri-axis accelerometer that is amenable to be sensed in all three axes of the tri-axis accelerometer. - View Dependent Claims (9, 10, 11)

12. A sensing assembly with a multi-axis accelerometer type sensor, to be used as a sensor in an intrusion detection fence of the taut wires type, comprising
base means for installing said assembly on a sensor'"'"'s pole of said fence; - and
movement converting means that, from an instant a taut wire to which said sensor is allocated, is loaded as it happens on occurrence of an intrusion attempt through it, converts movement of said taut wire to a movement of said multi-axis accelerometer that is amenable to be sensed in at least two of its axes. - View Dependent Claims (13, 14)

15. A method for sensing intrusion attempts through a taut wires type of intrusion detection fence, the method comprising the steps of:
-
connecting a multi-axis accelerometer to a taut wire of said taut wires type intrusion detection fence; converting movement of said taut wire as it occurs when an intrusion attempt is taking place through it, to a movement of said multi-axis accelerometer that is amenable to be sensed in its axes. - View Dependent Claims (16)
