In the general security monitoring system installation, HD network camera and ordinary camera installation and debugging methods are basically the same, but we must pay attention to the lens selection, because the quality of the lens is not good, or the matching is not good, to a large extent will be Affect the definition of the picture, for example, the infrared night vision system camera is best to use infrared lens, and 1/3 inch CCD is generally equipped with 1/3 inch lens, 1/2 inch CCD is generally equipped with 1/2 inch lens, The focusing and debugging of the lens must be well adjusted during installation and debugging. In particular, the rear focal plane of the camera must be adjusted. In many cases, the unclear focus of the lens will cause the image to be blurred, which cannot meet the high-definition requirements. In addition, the camera's protective cover can not be ignored, the front end of the gun-type protective cover glass can not use the normal flat glass, but must use better optical glass, the general flat glass of the image of the analytical power of a very powerful weakening effect, use The spherical shell should pay attention to the fact that the curvature of the spherical surface must be smooth and smooth. It is better not to align the lens with the upper edge of the spherical shell, where the refractive power of the light is large, and even the sharpness of the image is seriously affected. It is important to note that no matter what type of housing, the light in the housing should be as low as possible, and the distance from the lens to the housing should be as short as possible. This can minimize light pollution in front of the lens and help improve the image. The clarity.
From the perspective of real product and system configuration, megapixel-class high-definition applications are basically formed, such as front-end megapixel camera, transmission, interface, coding, image processing applications, output, display and other aspects of product technology, and application systems. The platform, based on the analysis of this topic, basically has the basis for operation. Although everyone in the industry generally believes that high-definition monitoring is an inevitable trend in the development of the industry and the market, from the perspective of real market applications, users of various industries currently have no concrete practical psychological preparation.
According to the current information, at present, the products of companies such as SkyView, Sony, Axis, and Hikvision have been or are being used in millions of high-definition network monitoring systems in some major cities. With the increase of these application cases, users will more and more perceive the different visual effects and detail display capabilities of high-definition monitoring systems. And promoted by the demonstration effect of sample cases, attracting more high-end users who have high-definition image requirements to join this application camp, especially those who have good local area network or optical fiber resources, they want to start network HD system applications, It is easier.
From the user's psychology, they are the first to care about the clarity of the image. However, they also worry that in the past, we used a digital-analogue system, everyone felt mature and stable, and the operation was handy. What about the stability of megapixel HD? Is it convenient to use? When something goes wrong, isn't it easy to deal with it, or is it an engineering integrator to help with it? Therefore, the sample engineering application case is the best way to get rid of such user concerns, and the sample project is also conducive to manufacturers and engineering integrators to find and solve problems in the specific application process, thereby promoting the further improvement of products and systems.
