The lens is the eye of the camera, is an essential part of high-definition images are acquired. In front of the monitor project design planning, only to understand the type of lens and its application way, application features and understand its collocation, can play the best imaging lens. In the current domestic classification, surveillance cameras can be roughly classified into ten types as follows. • fixed aperture lens: fixed focus and fixed aperture, it is mainly used for ambient light fixed place of. , manual aperture lens: the lens aperture is adjustable, it is mainly used for ambient light fixed place but of light and shade. • automatic aperture lens ( DC - 驱动器) : fixed focal length, the use of DC voltage driver used in place of fixed scope and ambient light variability; • automatic aperture lens ( 视频- 驱动器) : fixed focal length, the use of video signal drive used in place of fixed scope and ambient light variability; • aperture manually zoom lens: mainly used in indoor environment light place degree and range of different sizes. • automatic aperture zoom lens: mainly used in outdoor environment light place degree and range of different sizes. • machine lens ( 在- - - - - - 板) : give priority to with tie-in infrared cameras, fit for indoor and outdoor; Panoramic view fisheye lens: mainly used for indoor environment light degree and range is specific to the size of the place; Electric zoom lens: remote control focal depth of field and aperture, light degree of uncertainty and the range of depth of field is mainly used for indoor and outdoor environment size can be adjusted in accordance with the requirements of place; Pinhole camera ( 销, 孔) : it is mainly used for hidden monitoring and ambient light and scope of specific places. Scene classification by above can see, all kinds of lens differ in their use and application of major environmental needs. Therefore in practical application, how to perfect collocation, how to choose under different use place and Angle monitoring camera lens, also is a big test for engineering contractor.
