Abstract
A subscriber control circuit adapted to be incorporated in an united home security system is disclosed. The control circuit includes a plurality of client-side monitor/control servers, each serving to detect and control the situation at the subscriber and connected to a remote administrating and monitoring device via a public telephone network. The remote administrating and monitoring device is capable of transmitting alarm signal to an alarm transmitting network. The client-side monitor/control server also includes a central processing unit, a radio frequency receiver for receiving a detection signal from wireless sensing elements and an encoder for receiving and processing a detection signal from cabled sensing element. A DTMF based receiver connects the central processing unit to the remote administrating and monitoring device to receive a DTMF signal transmitted through the telephone line and transmit the received DTMF signal to the central processing unit. A dialer circuit is coupled to the central processing unit for performing automatic dialing operation.
