The future development trend of ipcamera

The wifi ipcameras were long enough in the market, the first being the axis published in 1996. At first, the technology, and as a result of image quality, the network surveillance cameras are very inferior to professional analog cameras. They are seen only as a mere use of something outside the web application in the video transmission via LAN and Internet. The purpose of the network camera is to take advantage of network technology and the Internet, as well as work with digital images into new applications rather than as a video surveillance and security camera for positioning. But things change - the network monitors the camera and changes. The new model, which began in 2004, has appeared on the market, using state-of-the-art networking and video technology, allowing it to walk in functionality and transmit image quality in the most advanced analog camera-level network surveillance cameras, and in many ways, We will see in the following, and constantly go beyond them. Future trends in network surveillance cameras When considering a broader range of unified video surveillance systems and network networks, but a simple comparison of the two camera types, there are many factors that must be considered that affect the needs of users: they are the principles of the camera , An open system, which for development, flexibility and the possibility of combining, technology and its development prospects, and so on. However, in this article we will discuss the ten most important differences between network surveillance cameras and simulated loss of universal access to functional, and why these factors must understand and consider the type of cells in the development of selected surveillance systems.

1. the end of the problem of staggered.
 High resolution (4CIF) works in interlaced mode, which means that every two fields (or fields), which contain odd and even lines by the analog camera's image. When displaying the area even moving the object at low speed, the moving object, especially the edge of the image is blurred - there is a "comb" effect. It is generated because of the delay in the updated frame with odd and even rows of fields. The network surveillance camera uses a progressive scan - a method that provides a better display of moving objects. This more advanced technology can be created by creating a single frame, odd and even lines, which provide very clear images even at high speed moving objects.
2. the power of Ethernet technology to improve reliability and reduce costs.
 Powering power to analog cameras often leads to problems and increases system costs. IEEE802.3af standard power over Ethernet (PoE) is a good solution for significant cost savings on devices that use it - there is no need for a camera powered infrastructure. Not applicable to analog cameras via Ethernet protocol Assume that the power supply is available to the network device that is powered by a switch that supports standard, or standard network cabling (twisted pair) CAT5, for data transmission and video-specific converters. It promises to give the user the greatest benefit as it uses a single standard that is supported by all network devices - can be used without worrying about compatibility issues with different manufacturers of technology. The use of the PoE protocol provides another advantage: all devices, including cameras, can be operated by connecting an uninterruptible power supply and in the case of a surge or turn off the system power.
 3, resolution.
 Analogue cameras support TV standard NTSC / PAL, one of which resolves the corresponding transmission to 0.4 megapixel 4CIF video. After a high-resolution display, allowing the use of multiple megapixel camera resolution information display, the appearance, the user also began to put higher requirements, equipment and video-camera. The increasing demand for camera resolution began to appear in the video surveillance market. The higher resolution network surveillance cameras offer a smaller part of the views and can cover a large viewing area. This will ensure that the investment in the security system, web-based cameras will not be wasted because there is no additional cost of image processing to identify individual criminals as well as various small items or parts. Megapikselnye webcams can also be used in cameras with zoom lenses where, in some cases, locating cells.
