Description

L'invention concerne une caméra de surveillance à support intégré pour la surveillance des locaux publics oui privés.The invention relates to a surveillance camera with integrated support for monitoring public and private premises.

Les caméras de surveillance connues, comportant un dispositif de prise de vues enfermé dans un boîtier, sont généralement installées sur un support indépendant du boîtier et ont des fils de connexion d'entrée-sortie apparents, ce qui rend la caméra vulnérable et sujette à ces actes de vandalisme. Par ailleurs, elles ne sont généralement pas discrètes, donc facilement repérables et elles sont difficilement, voir pas du tout, orientables ce qui ne permet pas de pouvoir les installer n'importe où. Leur installation n'est pas immédiate et nécessite un outillage adéquat.Known surveillance cameras, comprising a recording device enclosed in a housing, are generally installed on a support independent of the housing and have visible input-output connection wires, which makes the camera vulnerable and subject to these acts of vandalism. Furthermore, they are generally not discreet, therefore easily identifiable and they are difficult, if not not at all, orientable, which does not allow them to be installed anywhere. Their installation is not immediate and requires adequate tools.

Il existe également des caméras encastrables qui sont donc discrètes et résistent mieux aux actes de vandalisme, mais leur installation est délicate, elles ne sont pas orientables et ne permettent pas de surveiller toutes les directions de l'espace.There are also built-in cameras which are therefore discreet and better resist acts of vandalism, but their installation is delicate, they are not orientable and do not allow monitoring of all directions in space.

L'objet de l'invention est de réaliser une caméra discrète, résistant au vandalisme, d'installation aisée sans aucun outillage, pouvant être facilement orientée dans toutes les directions de l'espace et étant adaptée à un positionnement sur un mur ou sur un plafond.The object of the invention is to produce a discreet camera, resistant to vandalism, of easy installation without any tools, which can be easily oriented in all directions of space and being suitable for positioning on a wall or on a ceiling.

Selon l'invention, la caméra de surveillance à support intégré comportant un dispositif de prises de vues placé dans un boîtier et des fils de connexion, est caractérisée en ce que le boîtier comporte une coque creuse enfermant le dispositif de prises de vues, une partie creuse comportant au moins un bras de cardan support de cette coque, une bague de fixation, support de la partie creuse et destinée à être fixée sur une surface d'un local à surveiller, des moyens d'articulations entre le bras de cardan et la coque permettant la rotation de la coque autour d'un premier axe U passant par le centre de la coque et perpendiculaire au bras de cardan, la partie creuse étant mobile autour d'un deuxième axe V de rotation perpendiculaire au premier axe U et parallèle au bras de cardan, et en ce que les fils de connexion passent de l'intérieur de la coque à l'intérieur de la partie creuse par l'intermédiaire des moyens d'articulation.According to the invention, the surveillance camera with integrated support comprising a recording device placed in a housing and connection wires, is characterized in that the housing comprises a hollow shell enclosing the recording device, a part hollow comprising at least one cardan arm supporting this shell, a fixing ring, supporting the hollow part and intended to be fixed on a surface of a room to be monitored, means of articulation between the cardan arm and the shell allowing rotation of the shell around a first axis U passing through the center of the shell and perpendicular to the gimbal arm, the hollow part being movable around a second axis V of rotation perpendicular to the first axis U and parallel to the gimbal arm, and in that the connection wires pass from the interior of the shell to the interior of the hollow part by means of articulation means.

D'autres particularités et avantages de l'invention apparaîtront clairement dans la description suivante donnée à titre d'exemple non limitatif et faite en regard des figures annexées qui représentent :

  • La figure 1 une vue éclatée d'un exemple de réalisation de la caméra, selon l'invention.
  • La figure 2 une vue du boîtier de la caméra montrant ses trois axes d'orientation selon l'invention.
  • La figure 3 une vue en coupe du boîtier montrant un exemple de motorisation de la caméra, selon l'invention.
Other features and advantages of the invention will appear clearly in the following description given by way of nonlimiting example and made with reference to the appended figures which represent:
  • Figure 1 an exploded view of an exemplary embodiment of the camera according to the invention.
  • Figure 2 a view of the camera housing showing its three axes of orientation according to the invention.
  • Figure 3 a sectional view of the housing showing an example of motorization of the camera according to the invention.

La figure 1 représente une vue éclatée d'un exemple de réalisation de la caméra selon l'invention. La caméra comporte un dispositif de prises de vues 10 et un boîtier constitué d' une partie enveloppe 40, appelée coque, d'une partie support 30 de la coque appelé chape et d'une bague de fixation 51 support de la chape. Le dispositif de prises de vues 10 est constitué essentiellement d'un circuit électronique associé à un système optique intégré, 11, d'un objectif 12, de fils 13, 14 de raccordement de l'alimentation électrique et du signal vidéo. La chape 30 formant support comporte un fond 31 et deux bras de cardan 32, 33 parallèles ; la coque 40 a une forme de préférence sphérique mais peut également avoir une forme cylindrique, parallélépipèdique, ou autre et est destinée à recevoir le dispositif de prises de vues 10. Elle est constituée de deux demi-coquilles creuses 41, 42 dont l'une comporte en son sommet A un orifice, par exemple en forme de cône tronqué, de diamètre adapté pour loger l'objectif 12 du dispositif de prises de vues 10 et pour permettre le réglage de la mise au point de l'image. Chaque demi-coquille 41, 42 comporte sur sa périphérie deux évidements 43 et 44 permettant le passage des fils 13, 14 et la séparation des fils d'alimentation électrique des fils de transmission des signaux vidéo. Ces deux évidements sont de préférence diamétralement opposés. Lorsque le dispositif de prises de vues, 10, est mis en place dans la coque 40, les deux demi-coquilles sont fermées par un système de fermeture, par exemple à clips ou à vis, ou par coincement par l'intermédiaire des orifices 34 et 35 de la chape, 30.FIG. 1 represents an exploded view of an exemplary embodiment of the camera according to the invention. The camera comprises a camera 10 and a housing consisting of an envelope part 40, called the shell, a support part 30 of the shell called the yoke and a fixing ring 51 supporting the yoke. The image taking device 10 essentially consists of an electronic circuit associated with an integrated optical system, 11, of a lens 12, of wires 13, 14 for connection of the electrical supply and the video signal. The yoke 30 forming a support comprises a bottom 31 and two cardan arms 32, 33 parallel; the shell 40 has a preferably spherical shape but can also have a cylindrical, parallelepipedic, or other shape and is intended to receive the camera 10. It consists of two hollow half-shells 41, 42 one of which has at its apex A an orifice, for example in the form of a truncated cone, of diameter adapted to accommodate the lens 12 of the camera 10 and to allow adjustment of the focusing of the image. Each half-shell 41, 42 has on its periphery two recesses 43 and 44 allowing the passage of the wires 13, 14 and the separation of the electrical supply wires from the wires transmission of video signals. These two recesses are preferably diametrically opposite. When the camera 10, is placed in the shell 40, the two half-shells are closed by a closure system, for example with clips or screws, or by wedging through the orifices 34 and 35 of the screed, 30.

La chape 30 est destinée à recevoir la coque 40 entre ses deux bras de cardan 32, 33. Elle est creuse et comporte sur sa face interne, aux extrémités des deux bras de cardan, un orifice 34, 35. Ces orifices 34, 35 sont disposés de façon à être en regard des deux évidements 43, 44 de la coque 40 et permettent d'introduire à l'intérieur de la chape 30, les fils 13, 14 de raccordement de la caméra. De cette façon les fils sont protégés, non apparents et difficilement accessibles aux personnes mal-intentionnées. Pour assurer le blocage de la coque 40 dans la chape 30, le fond de la chape est en pré-contrainte de façon à ce que les deux bras de cardan 32, 33 aient tendance à se resserrer et à ce qu'une friction soit assurée entre les deux bras de cardan et la coque 40. Dans la surface externe du fond 31 de la chape 30 sont aménagés des trous permettant de sortir les fils de raccordement 13, 14 afin de pouvoir les raccorder par l'intermédiaire d'une barrette de connexions 50. La chape peut alors être fixée, par exemple par un dispositif à clips, à une bague de fixation 51 vissée par deux vis 60 sur le mur ou au plafond.The yoke 30 is intended to receive the shell 40 between its two cardan arms 32, 33. It is hollow and has on its internal face, at the ends of the two cardan arms, an orifice 34, 35. These orifices 34, 35 are arranged so as to be opposite the two recesses 43, 44 of the shell 40 and make it possible to introduce inside the yoke 30, the wires 13, 14 for connecting the camera. In this way the wires are protected, invisible and difficult to access by malicious people. To ensure the blocking of the shell 40 in the yoke 30, the bottom of the yoke is pre-stressed so that the two cardan arms 32, 33 tend to tighten and that friction is ensured between the two gimbal arms and the shell 40. In the external surface of the bottom 31 of the yoke 30 are provided holes allowing the connection wires 13, 14 to come out in order to be able to connect them by means of a strip of connections 50. The yoke can then be fixed, for example by a clip device, to a fixing ring 51 screwed by two screws 60 to the wall or to the ceiling.

Lorsque la caméra est montée et fixée sur un mur ou au plafond d'un local, les fils de connexion ne sont pas apparents et la caméra présente l'avantage d'avoir l'aspect extérieur d'un spot lumineux. Elle est donc difficilement repérable et moins sujette à des actes de vandalisme.When the camera is mounted and fixed to a wall or to the ceiling of a room, the connection wires are not visible and the camera has the advantage of having the external appearance of a light spot. It is therefore difficult to spot and less prone to acts of vandalism.

La figure 2 représente une vue du boîtier de la caméra montrant ses trois axes d'orientation, selon l'invention. La structure du boîtier permet une orientation aisée de la caméra dans toutes les directions de l'espace. Les deux évidements 43, 44 de la coque 40 sont pourvus sur leur pourtour d'un épaulement 45, 46, faisant saillie. Lorsque la coque 40 est logée entre les deux bras de cardan 32, 33, les épaulements 45, 46 viennent s'appuyer sur les orifices 34, 35 qui constituent ainsi une articulation grâce à laquelle la coque peut tourner. La coque 40 peut donc tourner autour d'un axe U passant par son centre et perpendiculaire aux deux bras de cardan 32, 33. La chape peut tourner autour d'un axe V perpendiculaire à l'axe U et parallèle aux deux bras de cardan 32, 33. Enfin, la caméra peut être déplacée le long d'un axe W parallèle à la surface sur laquelle elle est fixée.Figure 2 shows a view of the camera housing showing its three axes of orientation, according to the invention. The structure of the housing allows easy orientation of the camera in all directions in space. The two recesses 43, 44 of the shell 40 are provided on their periphery with a shoulder 45, 46, protruding. When the shell 40 is housed between the two cardan arms 32, 33, the shoulders 45, 46 come to bear on the orifices 34, 35 which thus constitute a joint by which the shell can rotate. The shell 40 can therefore rotate about an axis U passing through its center and perpendicular to the two cardan arms 32, 33. The yoke can rotate around an axis V perpendicular to the axis U and parallel to the two cardan arms 32, 33. Finally, the camera can be moved along an axis W parallel to the surface on which it is fixed.

La figure 3 représente une vue en coupe du boîtier montrant un exemple de motorisation de la caméra, selon l'invention. La caméra étant orientable selon trois axes, U, V, W, elle peut être motorisée à l'aide de deux moteurs M1, M2, le moteur M1 faisant tourner la chape 30 et le moteur M2 faisant tourner la coque 40. Le moteur M1 est par exemple fixé sur une pièce solidaire de la bague de fixation 51 et entraîne la chape 30 par exemple à l'aide d'une roue dentée 52 moulée dans la chape 30. Le moteur M2 est par exemple fixé à la chape 30 et entraîne la coque 40 par un mécanisme comportant une courroie dentée 53 et un engrenage 54. La caméra peut alors être télécommandée.Figure 3 shows a sectional view of the housing showing an example of motorization of the camera according to the invention. The camera being orientable along three axes, U, V, W, it can be motorized using two motors M1, M2, the motor M1 rotating the yoke 30 and the motor M2 rotating the shell 40. The motor M1 is for example fixed on a part secured to the fixing ring 51 and drives the yoke 30 for example using a toothed wheel 52 molded in the yoke 30. The motor M2 is for example fixed to the yoke 30 and drives the shell 40 by a mechanism comprising a toothed belt 53 and a gear 54. The camera can then be remote-controlled.

L'invention n'est pas limitée à l'exemple précisément décrit, notamment il n'est pas indispensable que la chape comporte deux bras de cardan, un seul bras de cardan suffit. Cependant les deux bras de cardan assurent la friction de la coque et permettent de la bloquer alors qu'avec un seul bras de cardan, il faut prévoir un système de blocage de la caméra.The invention is not limited to the example precisely described, in particular it is not essential that the yoke has two cardan arms, a single cardan arm is sufficient. However, the two cardan arms ensure the friction of the shell and allow it to be blocked, whereas with a single cardan arm, a camera locking system must be provided.

De même, la caméra décrite comporte deux évidements 43, 44 sur chaque demi-coquille, 41, 42, ce qui permet de séparer les fils d'alimentation des fils de transmission des signaux vidéo, mais un seul évidement est suffisant, la caractéristique essentielle étant l'intégration des fils à l'intérieur de la chape 30 pour renforcer la résistance de la caméra contre des actes de vandalisme.Similarly, the camera described has two recesses 43, 44 on each half-shell, 41, 42, which makes it possible to separate the supply wires from the wires for transmitting video signals, but only one recess is sufficient, the essential characteristic being the integration of the wires inside the yoke 30 to reinforce the resistance of the camera against acts of vandalism.
