Abstract

La présente invention concerne un appareil pour caméra de surveillance capable de manœuvre de panoramique vertical et horizontal et de manœuvre d'obturateur. Cet appareil de structure simple et compacte, facile à rendre étanche à l'eau, est constitué d'une unité caméra, et d'une unité d'entraînement à moteur indépendantes de façon à garantir une meilleure étanchéité. Les fonctions de panoramique et d'occultation de la caméra tirent profit de la structure sphérique de l'unité caméra. Pour la rotation, l'unité d'entraînement à moteur comporte un pignon s'engrenant dans une crémaillère réalisée sur la surface extérieure de la sphère. L'appareil est pourvu d'un ensemble boîtier externe dont la partie avant est ouverte. Pour la fonction de panoramique horizontal ou vertical, on commande un balayage de l'unité sphérique à caméra dans une plage angulaire définie. Pour la fonction d'occultation, on amène une fenêtre de l'objectif de la caméra au moyen de l'ensemble boîtier externe en dehors des limites de la plage angulaire définir.
