Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video call system having a video phone automatic recognition function,

The present invention relates to a video call system having a video phone automatic recognition function, and more particularly, to a video call system in which a plurality of video phones are connected to a layer distributor, To a video calling system and a video phone having the same.

In the lobby where the apartment or house can be accessed outside, a lobby phone is set up to call someone in the house. Such a lobby phone is configured to transmit voice and a shot image to a video phone installed in a house.

Also, the video phone arranged in the house corresponding to the lobby phone can be configured to be able to talk with the person called in the lobby and display the image photographed by the lobby phone.

For example, in the case of a multi-family house having one or more outlets and a plurality of generations corresponding to each one of the outlets, a lobby phone is installed in the entrance door area of the B1 to B2 floor connected to the first floor entrance and the parking lot, A household video phone connected to the lobby phone is installed.

Between the lobby phone and the plurality of generation video phones, an interlock device and a floor distributor are installed which can transmit video signals from the lobby phone to all the generation video phones. Such a floor splitter is configured to transmit images photographed by the lobby phone to all-generation video phones as they are.

A generation video phone called in a lobby phone converts a photographed image transmitted from a layer distributor into an image and displays the image and the layer distributor is configured not to transmit a video signal to another uncommitted generation video phone.

Previously, each household video phone had an ID for each household, so it was necessary to correctly connect the lines of each generation video phone to the corresponding household port of the floor distributor during installation.

In other words, since the generation video phone is not equipped with the automatic communication function so that it is automatically recognized by the floor distributor, it is checked by the floor distributor or the lobby phone whether the generation of the video phone of each generation is connected through the floor distributor I had to go through the checkup that I had to do.

In addition, although the conventional video phone can connect a video line for one camera, a user environment for selectively using a camera image for a single house and a residential home has not been established at the initial installation. Accordingly, existing video phone systems have inconveniences to be installed using each video phone in which the user environment is built depending on whether the installed place is a single-family house or a multi-family house.
