Abstract :
A description is given of DMSA Line, a dual, magnetically coupled, slow propagation and attenuating line, which is the first practical transportable intrusion-detection line sensor. It is designed to be rolled out on the surface of the terrain to protect up to 150 m of perimeter. Since each processor can operate two zones, this constitutes up to 300 m per processor. When desired, the line can be rolled up and moved to another location
