Abstract

A cable TV security system, it is the system by using the internet of cable TV (CATV) to transfer the security alarm signal. It is principally by adding CATV data interface with dual-way transmission function to mainframe terminal of commercial security owned by user. Simultaneously, it is also adding symmetric CATV data interface to CATV host end. Therefore, it can use dual-direction intercommunication way to accurately transmit the alarm signal from user end to host end, to reach security function. Through immediately intercommunication way to reach disconnection detecting ability. It includes: A security monitoring equipment, a user end interface, a distributed internet, a host end interface, CATV security mainframe and security subscriber data managing system of CATV to compose it. And by using two communication ways of inquire-alternately and disconnection, the security monitoring equipment can be used to detect the signal from user end like as firing, stealing, gas and emergency. And by user end interface through distributed internet of CATV to transfer into host end interface, for judging the definition of signal, to connect with security duty center or through telephone net to connect with hospital, police headquarters or fire brigade, for decreasing the losses from disaster.
