Abstract

A barrier formed by a plurality of free-standing spaced-apart stations which are sensitive to events in a region between them. Each station includes a sensor responsive to an event to be sensed, and may be passive or a combination of emitter and sensor. The technology is preferably electromagnetic, or motion responsive.

Claims

1. A system for establishing a linear boundary subject to intrusion for detecting, annunciating and identifying the intruder, said system comprising:

a plurality of stations fixed in the surface at spaced apart increments from one another, each station having the capability of observing a sector between it and its next neighboring stations, said sectors overlapping each other at least in part, between their respective stations;

an annunciator responsive to intrusion into said increment; and

a visualizer enabling a supervisor to identify the event of intrusion.

2. A boundary system according to claim 1 in which each station is free-standing and separate from it neighbor station or stations, each station being communicable with a supervisory station.

3. A boundary system according to claim 2 in which said annunciator is a sensor selected from the group consisting of radiation detectors, acoustic detectors, motion detectors, vibration detectors, and image comparators, and competent to provide notice to a visualizer of the fact of intrusion.

4. A boundary system according to claim 3 in which each annunciator has an effective field extending at least past one-half the distance between neighboring stations, whereby to establish a continuous boundary between the two stations.

5. A boundary system according to claim 4 in which said fields extend past the next neighboring station, whereby to provide for redundancy in the event of disablement of one of the stations.

6. A boundary system according to claim 4 in which said radiation detector is responsive to radiation emitted by its respective station and reflected to it.

7. A boundary system according to claim 3 in which said station includes a camera adapted to capture an image of the region in which the intruder exists.

8. A boundary system according to claim 7 in which said camera can be tilted upwardly and downwardly, and can be panned from side to side.

9. A boundary system according to claim 2 in which said supervisory station is adapted to receive signals from a plurality of said stations.

10. a station for a boundary system adapted to form a part of linearly extending boundary comprised of a plurality of free-standing spaced apart said stations, said station having the capability of detecting and responding to an intrusion into a sector of its respective field, said station including an annunciator responsive to the intrusion, and a visualizer enabling a supervision to identify the event of intrusion.

11. A station according to claim 10 in which the annunciator is responsive to a sector selected from the group consisting of radiation detectors, acoustic detectors, motion detectors, vibration detectors, and image comparators.

12. A boundary system according to claim 11 in which said radiation detector is responsive to radiation emitted by its respective station and reflected to it.
