Description

  The present invention relates to a combined Internet videophone / intercom system.

  With the development of the Internet, Internet videophone systems that transmit and receive video signals along with audio signals have become popular. In the Internet videophone system, in addition to a one-to-one call between two Internet videophones, a call can be made between a plurality of Internet videophones such as chat and videophone conference. As such an Internet videophone system, for example, an Internet videophone system that makes a call by inputting a URL address into a general-purpose browser instead of a telephone number has been proposed (see Patent Document 1).

On the other hand, it has a common entrance intercom installed at the common entrance of the apartment building and a home intercom installed at each dwelling unit. An intercom system that connects a call with an entrance intercom and unlocks a common entrance door is known. As such an intercom system, for example, a system in which a plurality of electric locks 4 are controlled by a lobby intercom 1 has been proposed (see Patent Document 2).

  However, in the conventional intercom system, calls between the common door intercom and each dwelling unit intercom are often performed by analog signals, and the common front door intercom and the dwelling unit intercom are individually wired with telephone lines. The system was configured by using a TV joint reception system.

  In a conventional intercom system using a telephone line, a video signal cannot be sent, and only a voice call is made. In a conventional intercom system that uses a TV joint reception system, video and audio can be sent. However, a booster (amplifier) is installed between the common entrance intercom and each intercom unit intercom. Since it is necessary to make the signal level constant, there is a problem that adjustment at the time of installation is troublesome and time and cost are increased.

  In addition, in the conventional intercom system, when a new intercom system is introduced into an existing apartment house, there is a problem that it takes time and costs such as laying a new wiring. Moreover, the intercom for dwelling units is used exclusively for the intercom, although it has a handset and a display device.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide an Internet videophone / interphone composite system suitable for an apartment house that can be introduced in a short time and at low cost.
