HOME SECURITY SURVEILLANCE SYSTEM

摘要

A home security surveillance system has a plurality of terminal detectors one of which functions as a master, and the other function as a slave to constitute an in-house alarm network. The in-house network is linked to a server on the side of a service provider to transmit an aid-requesting signal through a gateway unit upon detection of a hazardous condition at each of the terminals. The detection terminal is provided with a configuration means and a set button which, upon being manipulated, activates the configuration means to send a configuration demand to the gateway unit and receive therefrom a configuration instruction by which the detection terminal is assigned as the master and the slave. The gateway unit is arranged to receive the configuration demand and read the master/slave index in its terminal status table so as to prepare the configuration instruction indicating whether such detection terminal is to be assigned as the master or slave.
