IPC network camera is undoubtedly now the first major theme of video surveillance areas:on the one hand, the rapid development of electronic and network technology greatly enhance its value and scope; the other hand, the rapid expansion of the global security needs as well as users increasingly high requirements also stimulated the development of the network camera. IPC network cameras as long as the plug on the wire can be used, with no computer, no video capture card, there is no monitoring of local restrictions, open the Web page will be able to monitor at any place, and to support multiple clients simultaneously monitor browsing, easy high-definition low network bandwidth transmission of the image, the more common version of the camera image clearer, and night vision, audio transmission, dynamic alarm, you can set the alarm time zone, Abnormal automatic recovery, automatic connection after network outages and other new features. In the era of analog monitor, users vague, full of snow is already a noise monitor screen do nothing but complain incessantly, because it was the best cameras on the market can only be D1 quality, pixels, in theory, only a maximum of 40 million.In non-security areas, it is overwhelming digital camera, camcorder, PC camera, cell phone camera, or even hundreds of millions of millions of pixels. The first major security surveillance cameras as assistant simulation class monitoring products can not meet the user needs, then, "HD" became the first big demand, but, with the high-definition picture quality, low-light, wide dynamic, intelligent, etc. etc. in order to achieve a higher level of demand, it has value. With the security monitoring by the increasingly high-end dedicated civilian areas, the scope of application of IPC network cameras are increasingly being used, a lot of monitoring conditions are poor, dimly lit places also require the installation of versatile camera,especially low-light cameras. Currently, IPC network cameras have been widely used in the fields of financial, cultural, hotel, office buildings, residential property management. IPC network camera surveillance system using the existing cabling network transmission images,and real-time monitoring. Front-end system requires less equipment, the connection is simple, only the rear end to a software system. Major equipment IPC network camera system using an embedded real-time operating systems, the required equipment is simple, and images are transmitted via the network cabling implementation, system reliability is very high. System equipment required is extremely simple, the whole control system implemented by the back-end software systems, eliminating the traditional analog surveillance system in a large number of devices, due to the transfer images via the network cabling, eliminating the need for a large number of video coaxial cable, reduce costs. System set up different levels of user rights, only the most senior authority in order for the user to set or change the entire system, the user is not authorized to receive less than the image. Installation of the system is extremely simple to install and use the software system is also very easy to understand. In terms of maintenance, wiring system is very simple, and very high reliability of main equipment, maintenance of good performance, and enables remote maintenance. When users need to increase the monitoring point, when the monitoring host, only need to add a network camera to IPC through the existing network, without the need for changes to the existing wiring system what to do. Using the Internet to send real-time images, such as cross remote offices, buildings and other monitoring: chain of cause, large factories room, remote child care for the elderly, public buildings, and no danger of environmental monitoring, financial institutions branches of monitoring, traffic supervision, error alarm resolution and so on. Select IPC network cameras to assess the nature and function. Another thing to watch is the resolution. Resolution is very important, because it determines the clear image. Higher resolution images are better, easier to identify suspicious or criminal activity. Overall, the network camera system that can provide very useful monitoring solution, especially in large-scale monitoring area. These types of cameras can provide excellent images, and can help maintain a certain degree of security. In general security monitoring systems, installation and commissioning methods IPC network cameras and ordinary camera is basically the same, but must pay attention to good lens optional, because the poor quality of the lens, or bad option largely affects the clarity of the screen. Installation commissioning commissioning must adjust the lens focus is good, especially the back focal plane of the camera to align, often focusing lens unclear cause blurred image, reach high-resolution requirements. Another guard IPC network camera can not be ignored, the front glass shield gun can not be used generally flat glass, but must adopt better optical glass, flat glass for the general resolution of the image has a very powerful role in weakening , the choice of spherical enclosure should note that the curvature of the sphere must be a smooth transition, it is best not to put the lens at the upper edge of the sphere, light refraction larger force here, even seriously affect the clarity of the image. It is important that no matter what kind of cover, the best light as low as possible within the enclosure, the distance between the lens cover is as short as possible, so make the front of the lens to reduce light pollution to a minimum, help to improve image clarity.
