SECURITY SYSTEM FOR EXPENDING GUARD AREA

摘要

PURPOSE: An expansion monitoring system which uses a single guard host device is provided to reduce private guard service costs by integrating security areas. CONSTITUTION: A plurality of sensors(50a-50n) has a unique code and senses whether an intruder exists or not. A sensor expander(52) includes a plurality of sensor connecting terminals connected with the plurality of sensors. The sensor expander has a unique code and connected with a guard host device(102). A reader individually establishes a border about a plurality of virtual security areas and inputs a release signal. The guard host device comprises a connection terminal connected with one or more sensor expanders and transfers an input signal of the reader and a sensing signal to a control server(100). The control server establishes the plurality of virtual security areas by collecting the plurality of sensors connected to the guard host device with fixation number according to the request of a member.
