Abstract: A housing assembly for housing a surveillance television camera comprises a housing member to house the surveillance television camera therein, having a front wall provided with a window paned with a glass filter through which the surveillance television camera receives light rays representing the scene of a surveillance zone, and a flange to be fastened to a fixed structure; and covering member to cover the housing member, having a front wall provided with an opening which is positioned opposite to the window of the housing member when the covering member is put on the housing member, and capable of covering the housing member so that the surveillance television camera housed in the housing member will not be perceptible. Since the housing assembly is simple in shape and appearance and can be colored in a color harmonizing with the ambient color, the housing assembly is scarcely noticeable and does not make people aware of being under surveillance.
