Summary:PURPOSE: A security system using a shielded twisted pair cable is provided to secure 100 percent of accuracy without false alarm by removing a response to an unnecessary interference phenomenon such as animal, snow, rain, lightening, high voltage power line, and train. CONSTITUTION: A security system using a shielded twisted pair cable comprises a shielded twisted pair cable(100), an end part(200), and an analog sensor unit(300). The end part is formed on one side end of the shielded twisted pair cable. The other side of the shielded twisted pair cable is connected to the analog sensor unit. The shielded twisted pair cable changes static electromotive force according to the external power or impact. The analogue sensor unit detects change of static electromotive force of the shielded twisted pair cable according to the input of the negative charge among the power outage electromotive force.
