The invention relates to a device for monitoring objects (O), in particular for monitoring industrial environments, such as for example, paper factories and production and/or finishing processes carried out therein on a paper, cardboard or other fibre material web (B), with a monitoring camera (3), said camera (3) being arranged with the lens (4) in a rotationally symmetrical protective housing (2), rotating about a rotational axis (1). According to the invention, the protective housing (3) is mounted at one end (2.1) thereof on a rigid hollow shaft (7) and at the coaxial opposing end (2.2) has a blast tube (12) which rotates in conjunction therewith or which transforms into the same and the protective housing (2), including the blast tube (12), may be pressurised with compressed air.
L'invention concerne un dispositif de surveillance d'objets (O), en particulier, de surveillance d'environnements industriels tels que, par exemple, des papeteries, y compris les processus de fabrication de bandes continues de papier, de carton ou autres bandes de matière fibreuse (B), dispositif comprenant une caméra de surveillance (3), dont l'objectif (4) est disposé dans un boîtier de protection (2) à symétrie de rotation, monté tournant autour d'un axe de rotation (1). L'invention est caractérisée en ce que le boîtier de protection (3) est monté à l'une de ses extrémités (2.1), sur un arbre creux, rigide (7) et présente, à son autre extrémité coaxialement opposée (2.2), un tube de soufflage (12) également entraîné en rotation, ou bien se raccordant à cette extrémité, et en ce que le boîtier de protection (2), y compris le tube de soufflage (12), est soumis à l'action d'air comprimé.
