Translational wing gate security surveillance

Time:2012-04-24From:Shenzhen Zimtech Technology Co., Ltd

       Shenzhen translation wing gate security surveillance cameras four major development directionFor millions of high-definition picture monitoring lens, the imaging quality is the fundamental, security monitoring product form and application scenarios the myriads of changes, which requires millions of high-definition surveillance camera in various scenes of the complex light environment, must have excellent imaging quality. Single lens from the future development direction, has four major development direction. Shenzhen translation wing gateHigh definitionDefinition two important indicators include the resolution and contrast. Resolution refers to the lens reproduction shot scenes details ability, the higher the resolution, the picture is clear and exquisite; contrast refers to the reappearance of scenes have been proactive in low contrast detail, shading layer of ability, the higher the scene of a picture contrast, clean-cut, edge sharpness, the level of rich, strong texture, bright tone. High resolution and low contrast between the lens, image contour was not clear, dark tone contrast, plain, gives people sense perception but not clear. Many domestic lens is such, but also many manufacturers to promote one million HD and SD lens lens, but sense no much difference, this is market cool reason. Some of the resolution of the lens is not high, but is a great contrast, it gives people a good feeling of the lens. So the contrast and resolution are to reach a certain height, is the real ideal million high-definition camera.Large caliber sizeLarge caliber is refers to the lens through light, mainly in the brightness of the screen, in the environment of dark and night mode compared to the small diameter lens has better performance. Miniaturization is the lens has the advantages of compact structure, can be applied to different products on the device and decrease the size of the product. Compared with the foreign megapixels surveillance camera, the aspheric technology mature, often with a lens, the focal length, aperture and large enough, small structure, high definition. The major domestic manufacturers are in slowly explore lens aspheric technology, strive for an early mature application in megapixels surveillance footage of new product development, with foreign manufacturers to compete.Day and night, defocusIn that day the image quality under the premise, users of the night like quality requirements are increasingly high, you can use the ED ( low high refractive index dispersion ) glass better correction of chromatic aberration, improve and imaging by confocal capacity and image quality. In recent years, the major glass manufacturers in their efforts to promote ED glass.Stray light removingStray light include stray light and the ghost. Stray light is the mechanical components of the reflective rainbow type stray light, stray light can pass through the lens and the inner wall spacer extinction of perfect elimination. Ghost is a light in the shots of the interior mirror plate in the frame of the multiple reflections between two imaging, ghost and light object contour is similar, can not be completely eliminated, only through the plating multilayer antireflection coating to minimize. A comprehensive performance excellent HD a surveillance camera, the stray light removing should have excellent performance in strong light environment performance quality, matching its millions of high-definition surveillance camera name.
