Abstract

System which allows visual identification of persons who come to the entrance of a building, on the screen of the television receiver located in the apartment. It consists of a television camera at the entrance to the building, linked to a simplified television transmitter which inserts the information received into the circuit of the building's communal television antenna so that it is received on one of the available channels of the television receiver located in the apartment. The system is particularly useful in buildings containing a large number of apartments.

Description

La présente invention concerne un système qui permet l'identification visuelle des personnes qui se présentent a l'entrée de l'immeuble, sur l'ecran du récepteur de télévision qui se trouve dans l'appartement. The present invention relates to a system which allows the visual identification of people who present themselves at the entrance of the building, on the screen of the television receiver which is located in the apartment.

Dans les systèmes classiques d'identification visuelle , l'identification du visiteur se fait sur l'ecran d'un moniteur de télévision installé dans ce but, dans l'appartement. In conventional visual identification systems, the visitor is identified on the screen of a television monitor installed for this purpose in the apartment.

Dans cette conception, les systèmes existants présentent les inconvénients suivants :
Ils ne sont pas conçus pour les immeubles qui ont un grand nombre d'appartements. In this design, the existing systems have the following drawbacks:
They are not designed for buildings that have a large number of apartments.

Leur montage est difficile et nécessite des circuits individuels pour chaque appartement. Their assembly is difficult and requires individual circuits for each apartment.

Ils sont chers, parce que chaque appartement est obligé d'avoir son propre moniteur de télévision. They are expensive, because each apartment is obliged to have its own television monitor.

Ils sont incommodes, parce qu'ils imposent le déplacement jusqu'd l'endroit où on a installé ce moniteur. They are inconvenient because they require moving to the place where this monitor was installed.

Dans certaines conditions, les dimensions réduites de l'ecran rendent difficile l'identification du visiteur. Under certain conditions, the reduced dimensions of the screen make it difficult to identify the visitor.

Le système selon l'invention permet
L'identification visuelle des personnes qui se présentent à l'entrée de l'immeuble, dans tous les appartements, quel que soit leur nombre.The system according to the invention allows
The visual identification of people who present themselves at the entrance of the building, in all apartments, regardless of their number.

I1 n'y a aucune difficulté d'installation. There is no difficulty in installation.

L'investissment fait est minimal, parce que l'image du visiteur est réceptionnée sur l'une des channes du récepteur de télévision de l'appartement et parce que le système d'interphone existant s'intègre dans le nouveau système vidéo. The investment made is minimal, because the image of the visitor is received on one of the channels of the television receiver of the apartment and because the existing intercom system is integrated into the new video system.

Les dimensions de l'ecran permet l'identification précise en n'importe quelles conditions. The dimensions of the screen allow precise identification in any conditions.

Commodité maximale et 1 Wvantage d'identifier le visiteur avant de lui parler. Maximum convenience and 1 W advantage to identify the visitor before speaking to him.

Le système selon l'invention comporte
Une caméra de télévision à l'entrée de l'immeuble.The system according to the invention comprises
A television camera at the entrance of the building.

Un émetteur simplifié de télévision. A simplified television transmitter.

Le réseau d'antenne collective de télévision de l'immeuble. The building's collective television antenna network.

Le visiteur se trouve à l'entrée de l'immeuble où il pousse 4 bouton de sonnette de l'interphone, qui abrite aussi une camera de télévision.The system according to the invention operates as follows:
The visitor is at the entrance of the building where he pushes 4 doorbell button of the intercom, which also houses a television camera.

La caméra de télévision réceptionne l'image du visiteur et la transmet à l'émetteur de télévision. The television camera receives the image of the visitor and transmits it to the television transmitter.

L'émetteur de télévision introduit l'information reçue dans le circuit de l'antenne collective de télévision. The television transmitter introduces the information received into the collective television antenna circuit.

Le récepteur de télévision de l'appartement , par l'intermédiaire de l'une des chaînes disponibiles réglée sur le canal de l'émetteur, réceptionne l'image du visiteur par le simple changement de la channe visionnée au moment où on entend la sonnette de l'interphone. The apartment's television receiver, via one of the available channels set to the transmitter channel, receives the image of the visitor by simply changing the channel viewed when the doorbell is heard. of the intercom.
