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.

Claims

1. A video recorder removably mounted on a windscreen or a glass pane, comprising:

a housing having sidewalls, including a front side and a back side, forming an enclosed internal cavity within the housing, the front side being substantially flat and having a window through which only an external optical radiation from outside passes into the enclosed internal cavity, wherein the housing is configured for removable attaching onto the windscreen or the glass pane; and

a video camera arranged within the internal enclosed cavity, wherein the optical axis of the video camera lens is oriented toward the window in such way that allows the video camera to acquire the optical radiation passed into the housing solely through the window and falling onto the video camera image sensor, for obtaining an image signal from the acquired external optical radiation.

2. The video recorder according to claim 1, wherein the external optical radiation is at least one of visible light or IR-radiation.

3. The video recorder according to claim 1, wherein the window on the front side of the housing is surrounded by a closed surface of the front side.

4. The video recorder according to claim 1, wherein the housing is fastened to the windscreen by use an adhesive substance applied on the front side of the housing.

5. The video recorder according to claim 1, further comprising a gasket of elastic or resilient material, having an opening substantially coinciding by its form and arrangement with the form and the arrangement of the window in the front side of the video recorder housing, wherein the gasket is attached by a first planar surface to the front side of the housing by a first adhesive substance, wherein the video recorder together with the attached gasket is fastened to the windscreen by a second adhesive substance applied on a second planar surface, opposite to the first planar surface, of the gasket.

6. The video recorder according to claim 5, wherein the first and second adhesive substances are identical.

7. The video recorder according to claim 1, further comprising a gasket of an elastic or resilient material and a firm plate, the gasket and the plate each having an opening substantially coinciding in the form and arrangement with the form and arrangement of the window in the front side of the video recorder housing for matching the openings and the window with each other in the operating state of the video recorder;

wherein the gasket is attached to the plate by a first adhesive substance applied on a first planar surface of the gasket;

wherein the video recorder is fastened to the windscreen through the gasket by a second adhesive substance applied on a second planar surface, opposite to the first planar surface of the gasket, thereby the housing of the video recorder is fastened to the plate in a detachable manner.

8. The video recorder according to claim 7, wherein fastening of the housing in the detachable manner to the plate is implemented by a counterpart locking profile being any one of:

(a) latches located along the edges of the plate and fixing the housing to the plate;

(b) a male locking profile located on the surface of plate side facing the front side of the video recorder housing and engaging with a female locking profile in the housing front side;

(c) at least one ridge on the plate side facing the front side of the housing, extending along the plate surface and slidably engaging with a groove in the housing front side;

or (d) a single ridge located on the plate side along a periphery of the plate engaging a reciprocal groove in the housing.

9. A video recorder configured to be removable mounted on a windscreen or a glass pane, comprising:

a housing having sidewalls, including a front side and a back side, forming an enclosed internal cavity within the housing, the housing front side being substantially flat and having a window through which only an optical radiation from outside passes into the enclosed internal cavity;

a plate having an opening substantially coinciding in its form and arrangement with the form and arrangement of the window in the front side of the housing, and having a male locking profile for interlocking with a female locking profile on the housing for abutting the plate onto the front side of the housing, the plate having an axial fixture provided at its edge for enabling pivoting motion of the housing relative to the plate,

a gasket for fastening by a first adhesive, applied onto a first planar surface of the gasket, to the plate and fastening by a second adhesive, applied onto a second planar surface of the gasket, to the windscreen or the glass pane, the gasket having an opening substantially coinciding in its form and arrangement with a form and arrangement of the window in the front side of the housing; and

a video camera arranged within the internal enclosed cavity, wherein an optical axis of video camera lens is oriented toward the window in such way that allows the video camera to acquire external optical radiation passed into the housing solely through the window and falling onto the video camera image sensor, for obtaining an image signal from the acquired external optical radiation.

10. The video recorder according to claim 9, wherein the first and second adhesive substances are identical.

11. The video recorder according to claim 9, wherein the external optical radiation is at least one of visible light or IR-radiation.
