发明名称 METHOD FOR CONNECTING CALL BETWEEN A DOOR CAMERA OF A VIDEOPHONE AND AN EXTERNAL PHONE
摘要 A method for connecting a call between a door camera of a video phone and an external phone is provided to store a plurality of telephone numbers in the video phone to increase the possibility of connecting the door camera and the external phone. A door camera collects information on a visitor and transmits the information to a microcomputer circuit of a monitor when a call switch is pressed(415). When the microcomputer circuit receives the information, the microcomputer determines whether a video phone is in an absence mode(420). When the video phone is in the absence mode, the visitor information and the telephone number of an absent resident, which is previously stored in the microcomputer circuit, are transmitted to an external server(430). When the video phone is not in the absence mode, only a function of connecting a call between the door camera and the monitor is executed(490). The visitor information is transmitted through e-mail to the telephone of the absent resident by using the telephone number of the resident(440). Only the function of connecting a call between the door camera and the monitor is executed when the video phone does not receive a call request from the telephone of the absent resident. When the video phone receives the call request from the telephone of the absent resident(450), a call ID circuit detects the telephone number of the telephone of the absent resident and compares the detected telephone number with the telephone number of the resident, which is previously stored in the microcomputer circuit(460). When the two telephone numbers are identical to each other(470), a call between the door camera and the telephone of the absent resident is connected(480). When the two telephone numbers are not identical to each other, the call between the door camera and the telephone of the resident is not connected, and the function of connecting a call between the door camera and the monitor is executed.
