FIELD: physics, video technology. ^ SUBSTANCE: camera includes image sensor module, suitable objective lens, particularly wide-angle lens, and holder. The lens features threading which, via the holder and elastic spacing piece, is screwed to match thread of image sensor, so that the thread performs two functions, namely function of image sensor module connection by the lens, and function of focusing by adjusting optic distance between the image sensor module and the lens. Lens thread passes through traverse holes in the holder and elastic spacing piece in the form of elastic ring positioned between the lens and holder. Various vision directions of image sensor module can be adjusted by rotation element. ^ EFFECT: camera suitable for house intercom, with more flat and compact design and improved functional capability. ^ 22 cl, 12 dwg |
