Abstract

PURPOSE: A video door phone connected to external equipment through video and audio and a service method therefor are provided to be capable of confirming visitors even during outgoing through Internet by mounting an outgoing mode shift key and a CPU in the video door phone and connecting the video door phone to a web server or a home server. CONSTITUTION: An outgoing mode is selected by a key input(101) and a network number of designated external equipment(140) is input to a CPU(100). At this time, the video door phone is connected to a web server(131), and then the network number is transmitted to the equipment through Internet(130). The equipment(140) receives a signal of a calling key(112), and again transmits the signal to the video door phone to confirm images input through a camera(119) and an image selector(114).

Description

{Video doorphone linked external terminal with video and voice for service system}

1 is a basic configuration diagram of a conventional video door phone, and the pager 14 is attached to an external device to generate a pager signal by the visitor pressing. The camera 33 receives power and outputs a video signal by capturing an image of the visitor. The key input unit 11 generates a key signal when the playback and recording signals and the outing mode are selected. The CPU 10 controls the overall operation of the system. When the call key 14 generates a signal, the CPU 10 outputs a power supply control signal to the camera 33 and simultaneously outputs an image selection signal. The recording menu of the key input unit 11 is displayed. As the input, the visitor video signal is controlled to be recorded. The image selecting unit 13 outputs an image signal output from the camera 33 under the control of the CPU 10.

Also, the image memory 31 displays the video signal output from the video selection unit 13 or the video signal read out from the video memory 31 under control. The call circuit 22 transmits a call signal and a control signal between the internal circuit and the connection circuit, and the call SW 12 communicates with the visitor through the call circuit 22. The voice synthesizing unit 21 records the voice call signal transmitted / received through the call circuit 22 in the voice memory 23 or voice synthesizes and outputs a guide message recorded in the voice memory 23.

In the conventional video door phone having such a configuration, a video door phone system is generally divided into an indoor unit installed in a home and an outdoor unit installed outdoors.

When the visitor presses the bell of the outdoor unit, the camera attached to the outdoor unit is activated and an alarm is generated from the speaker of the indoor unit to show the visitor's appearance on the indoor unit's monitor.

Then, the indoor person can check the monitor provided in the indoor unit, and check the visitor through the microphone of the indoor unit, and at the same time, talk about the visit. However, such a general video door phone can be mutually available only when there is a person indoors. Visitors cannot achieve the purpose of visit when there are no people indoors, and people who live indoors can check who visited and who went out. It is a disadvantage of current video door phones.

Accordingly, the present invention has been proposed to solve the disadvantages of the general video door phone as described above, and an object of the present invention is to use a mobile communication terminal, an IMT2000 satellite communication terminal using an internal device or a home server having a web server function when going out. By inputting a designated communication number which can be directly connected to various information devices connected to the Internet, the video and audio connected to the external device of the video door phone and the inputted external device through general communication or the Internet are connected to the external device. In order to achieve the above object, the present invention (method) is to provide a video door phone and a service method that is, when you want to go out and set the mode to go out and input the communication number of the external device to specify Storing the information in a storage device of the internal device; When the bell is pressed, it is connected to an internal information communication device connected to an internal device having a web server function and connected to a designated communication device input to a storage device through the Internet. And controlling the video and audio to be interconnected.

The present invention relates to a video door phone and a service method for connecting video and audio to an external device, and is normally used like a video door phone, but using an internal device or a home server having a web server function when going out. When the absent visitor presses the bell attached to the external device by entering a designated communication number that can be connected to the external device, the visitor is automatically connected to the external device input to the internal device. The video door phone and the service method that can be divided into video and audio that can be divided into external devices

Hereinafter, described in detail with reference to the accompanying drawings, preferred embodiments of the present invention according to the technical configuration as described above.

2 and 3 are diagrams illustrating a connection configuration of a web server and an information communication network or an internal information communication device connected to a web server in a video door phone system to which the present invention is applied.

First, in order to use the present invention, the outgoing mode is selected by using the key input unit 101 and the communication network number of the designated external device is input to the CPU 100 for the setting of the outgoing mode 201.

In the above operation, the video door phone is connected to the web server unit 131. Then, when the visitor operates the call key 112 in step 204, the video door phone is connected to the Internet according to the instruction of the designated external device communication number stored in the CPU 100. The designated external device 104, which is transmitted to the designated external device at step 207, receives the call key 112 signal.

The designated external device 140 simultaneously receives the call key 112 signal received and operates the designated external device 140 to send a signal back to the video door phone while connected to the Internet 130 (204) of the visitor. In response to the pager 112 signal, the camera 119 and the image selector 114 check the image (step 208).

In the above step, the web server unit 134 replaces the web server 131 when the home server 131-1 is constructed in the video door phone installation place (205, 206) (206-1). May be replaced by step).

As described above, the present invention is equipped with an external mode switch key on the video door phone, the CPU can be installed or connected to a home server or connected to a home server, so that visitors can be checked while going out through the Internet, thereby providing both convenience for visitors and installers. It can be effective.

Claims (1)
