1. A security system for detecting an unauthorized activity and attempt to enter through an entrance of a secured area comprising:

  • an entrance barrier for controlling entry through the entrance including a plurality of intersecting structural tubular elements;

    at least a first intrusion sensor, including a sensor line, for sensing a first predetermined fault condition corresponding to an unauthorized attempt to move the barrier;

    a second intrusion sensor, including a sensor line, for sensing a second predetermined fault condition corresponding to one of a bend or a severance of a tubular element;

    at least one monitor unit for transmitting a sensor signal along the sensor line, and at least one receiver unit for receiving the sensor signal upon return;

    a monitor processor for receiving said sensor signal from said receiver unit and initially establishing a baseline level corresponding to the state of the sensor line in a secure condition, detecting when said sensor signal reaches a threshold level above the baseline level, and generating a fault signal in response to reaching or exceeding the threshold level corresponding to one of a movement, a bend, or a break in the sensor line; and

    a notification device communicating notice of the fault signal to security personnel.
