The call and intercommunication board permits the mounting of a television camera for a video intercommunication installation without requiring the modification of the various components. This board is formed by one or more juxtaposed assemblies each having a horizontal dimension equal to a predetermined "horizontal modulus". Each assembly is composed of elements having a vertical dimension which is a multiple of a predetermined "vertical modulus". A television camera is equipped with a parallelipipedic casing (10), and has a transverse dimension equal to said "horizontal modulus" and a vertical dimension equal to a multiple of the vertical modulus, such casing being mountable on a frame (18) in such a manner as to be able to be adjusted angularly with respect to the horizontal and such frame is in its turn mountable on the opening of a mounting box (52) capable of enclosing such casing and the frame, covering means, dimensioned with the same modularity, including a transparent wall in front of the lens of the television camera. Accessory components are also mounted, having the horizontal and vertical dimensions which are respectively equal to said horizontal modulus and to said vertical modulus or to a multiple of the latter. <IMAGE> |
