Perimeter security system

Abstract

A security system for detecting physical intrusion in a monitored area including a plurality of radio units arranged in a network around the monitored area to determine received signal strength and pass variations thereof through the radio units to a base station.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to wireless security systems and, more particularly, to wireless security systems for detecting physical intrusions or movements in a monitored area or perimeter and reporting any intrusions and / or movements.[0003]2. Description of the Prior Art[0004]There is a great need for wireless security systems to detect physical intrusions into monitored areas by human or other intruders and report the intrusion and its nature. In the past, wireless security or intruder detection systems have had the disadvantages of being complicated with respect to tracking an intrusion, of providing inaccurate readings in the presence of noise or interference and of utilizing expensive equipment not easily arranged to form a perimeter around an area to be monitored.

AI Technical Summary

Benefits of technology

[0009]The security system of the present invention can monitor physical intrusions into an area, either indoors or outdoors, by human or other intruders and report the intrusion and its nature to a user. Some of the uses for the security system of the present invention, due to its flexible and adaptable nature, include perimeter sensing for detecting humans crossing a particular perimeter, bread crumbs functioning, retracing the path of a human such as in a cave, secure transportation of containers and cartons, detecting human movement behind a wall, detecting humans caught in rubble, alarm systems for animals, such as pets, tripwire fencing for military applications, swimming pool safety, work site safety, work site theft prevention, traffic monitoring, and detection of illegal border (perimeter) crossing.

Problems solved by technology

In the past, wireless security or intruder detection systems have had the disadvantages of being complicated with respect to tracking an intrusion, of providing inaccurate readings in the presence of noise or interference and of utilizing expensive equipment not easily arranged to form a perimeter around an area to be monitored.
