Abstract: A video recorder mounted on a car windscreen. Sidewalls of a housing form an enclosed internal cavity housing a video camera. One sidewall of the housing is substantially flat, providing a fastening side for mounting the housing to the windscreen either directly or through a gasket, or through a gasket with a firm plate for forming a detachable fixation of the recorder to the windscreen. The housing fastening side, the gasket and the plate each have an opening of the same form and arrangement as the window. An optical axis of a video camera lens is directed through the cavity to the window, wherein an external radiation passing into the cavity and falling on the lens can be acquired by a camera image sensor for obtaining an image. Such a construction avoiding stray external light sources hitting the lens and avoids distortion of the received image from the external sources.
