A control method for united home security system includes steps of defining a set of signal codes which are transmitted between a client-side monitor/control server and a remote administrant through a public telecom-network by using multiple frequency signals. When the server sends signals to the remote administrant, a data string which is assembled by following a predefined format is received and checked by the remote administrant. An event handling process will be performed if the data string is correct. The remote administrant performs a predetermined handling process which is corresponding to the incident code sent by the server. The remote administrant start performing a rescue process when receiving an emergency/rescue handling signal from the server.
