20100079591 | WINDOW OF INFRARED SURVEILLANCE CAMERA - Disclosed therein is a window of an infrared surveillance camera, which can prevent that the window gets damp even though there is a difference in temperature between the inside and the outside of the surveillance camera due to a long time operation of the surveillance camera. The window includes: an illumination window mounted on a light path in front of an IR LED arranged around a camera module; a first lens window formed separately from the illumination window and mounted on an image introducing path in front of a lens of the camera module; an intercepting member having an assembly face where the illumination window and the first lens window are airtightly and closely combined with each other, the intercepting member being mounted between the illumination window and the first lens window for preventing that infrared rays are introduced from a light irradiation zone, where the IR LED is mounted, to a photograph zone, where the camera module is mounted; a combining ring assembled in front of the intercepting member for simultaneously restricting the illumination window and the first lens window; and a second lens window assembled to the combining ring and spaced apart from the first lens window through the combining ring so that a sealed air layer is formed between the second lens window and the first lens window. | 04-01-2010 |
