Abstract

The surveillance system is for stores, banks etc. It has a television camera driven by an electric motor along a rail inside ducting which may be suspended from the ceiling. The ducting resembles a large tubular light fitting. The lower half of the ducting is closed by a transparent U-shaped cover (2) metallised so that it acts as a one-way mirror obscuring the camera from view but allowing the camera operator to see everything in the field of view of the camera. The camera can pivot about the axis of the rail. A blinking light may be included to attract an observer's attention.

Description

  

  
 



   La présente invention a pour objet une installation de surveil
 lance comprenant au moins un appareil de prise de vues.



   On connaît le principe de la surveillance par caméras placées
 de façon fixe ou pouvant tourner sur leurs axes. Il est évident
 qu'une telle installation de surveillance présente un champ
 d'action limité car le champ visuel que ces caméras peuvent
 contrôler est trés restreint et est fonction des caractéristiques des
 objectifs. De plus ces caméras sont visibles.



   Ces inconvénients ne peuvent être ignorés d'un observateur, et la présente invention a pour but de les supprimer.



   L'installation de surveillance, objet de l'invention, est caractérisée par le fait que l'appareil de prise de vues peut se déplacer par asservissement le long de rails, le tout dissimulé par un cache en matériau transparent, dont une surface est métallisée de façon à le rendre réfléchissant pour un observateur tout en permettant la prise de vues par l'appareil. Par cette dissimulation et par cette translation on laisse ignorer le champ couvert par l'appareil de prise de vues. Cette ignorance du champ couvert permet une sérieuse économie tout en développant les possibilités de surveillance de l'installation.



   Le dessin annexé représente, à titre d'exemple, une forme d'exécution de l'installation de surveillance objet de l'invention, formée de sections mises bout à bout, pour atteindre la longueur nécessaire.



   La caméra 1 peut se déplacer le long des rails 3 dans un sens ou dans l'autre. Les rails 3 peuvent aussi être porteurs, par exemple, du courant d'alimentation du moteur et, entre autres, permettre les différentes liaisons de commande pour l'asservissement de la caméra.



   Le cache 2 fabriqué en matériau approprié est transparent depuis la caméra et est réfléchissant depuis l'extérieur, grâce à une métallisation appliquée sur toute la surface interne ou externe et sur toute sa longueur.



   La partie supérieure 4 est fabriquée dans une   matiére    opaque; elle sert de support à tout l'ensemble et permet la fixation de toute l'installation de surveillance aux plafonds, aux murs, ou à tous autres endroits idoines.



   Deux visières 5 sont disposées tout le long du cache et ont la fonction d'empêcher la pénétration de la lumière ambiante par le haut.



   REVENDICATION



   Installation de surveillance comprenant au moins un appareil de prise de vues, caractérisée par le fait que ledit appareil de prise de vues peut se déplacer par asservissement le long de rails, le tout dissimulé par un cache en matériau transparent dont une surface est métallisée de façon à le rendre réfléchissant pour un observateur tout en permettant la prise de vues par l'appareil.



   SOUS-REVENDICATIONS
 1. Installation de surveillance selon la revendication, caractérisée par le fait que la surface métallisée est recouverte partiellement par un produit ou un matériau opaque, laissant des ouvertures circulaires ou sous forme de fentes longitudinales derrière lesquelles l'appareil de prise de vues peut se déplacer.



   2. Installation de surveillance selon la revendication et la sousrevendication 1, caractérisée par le fait que le cache (2) est fabriqué dans un matériau parfaitement transparent incolore ou teinté.

 

   3. Installation de surveillance selon la revendication, caractérisée par le fait que le cache est muni de voyants lumineux clignotants ou non, destinés à attirer l'attention d'un observateur.



   4. Installation de surveillance selon la revendication, caractérisée par le fait que le déplacement de l'appareil de prise de vues est obtenu à l'aide d'un moteur, se déplaçant conjointement avec ledit appareil, ou fixé en un point de l'installation, commandé par un système d'asservissement à distance.



   5. Installation de surveillance selon la revendication, caractérisée par le fait que les rails et le cache sont constitués d'éléments ajustables les uns à la suite des autres, afin d'obtenir une installation de surveillance de longueur désirée et d'en faciliter le transport et la pose.

**ATTENTION** fin du champ DESC peut contenir debut de CLMS **.



   



  
 



   The present invention relates to a monitoring installation
 lance comprising at least one camera.



   We know the principle of surveillance by cameras placed
 fixed or rotatable on their axes. It is obvious
 that such a monitoring installation has a field
 limited action because the visual field that these cameras can
 control is very limited and depends on the characteristics of the
 Goals. In addition, these cameras are visible.



   These drawbacks cannot be ignored by an observer, and the present invention aims to eliminate them.



   The surveillance installation, object of the invention, is characterized by the fact that the camera can move by servo-control along rails, the whole concealed by a cover in transparent material, one surface of which is metallized. so as to make it reflective for an observer while allowing the camera to take pictures. By this concealment and by this translation, the field covered by the camera is ignored. This ignorance of the field covered allows serious savings while developing the possibilities of monitoring the installation.



   The appended drawing represents, by way of example, an embodiment of the monitoring installation which is the subject of the invention, formed of sections placed end to end, to reach the necessary length.



   The camera 1 can move along the rails 3 in one direction or the other. The rails 3 can also be carriers, for example, of the supply current of the motor and, among other things, allow the various control links for the servo-control of the camera.



   The cover 2 made of a suitable material is transparent from the camera and is reflective from the outside, thanks to a metallization applied over the entire internal or external surface and over its entire length.



   The upper part 4 is made of an opaque material; it serves as a support for the whole assembly and allows the fixing of the entire surveillance installation to ceilings, walls, or any other suitable places.



   Two visors 5 are arranged along the entire length of the cover and have the function of preventing the penetration of ambient light from above.



   CLAIM



   Surveillance installation comprising at least one camera, characterized in that said camera can move by servo-control along rails, the whole concealed by a cover of transparent material, one surface of which is metallized so to make it reflective for an observer while allowing the taking of pictures by the camera.



   SUB-CLAIMS
 1. Monitoring installation according to claim, characterized in that the metallized surface is partially covered by a product or an opaque material, leaving circular openings or in the form of longitudinal slits behind which the camera can move .



   2. Monitoring installation according to claim and subclaim 1, characterized in that the cover (2) is made of a perfectly transparent colorless or tinted material.

 

   3. Monitoring installation according to claim, characterized in that the cover is provided with indicator lights flashing or not, intended to attract the attention of an observer.



   4. Monitoring installation according to claim, characterized in that the movement of the camera is obtained using a motor, moving jointly with said device, or fixed at a point of the installation, controlled by a remote servo system.



   5. Monitoring installation according to claim, characterized in that the rails and the cover consist of adjustable elements one after the other, in order to obtain a monitoring installation of desired length and to facilitate the transport and installation.
