发布时间：2011-05-27 09:59:38 Print: Security monitoring systems, network monitoring is one of the main trends in the development of security market of the future. Application from the current market, wireless network monitoring can be divided into monitoring and cable monitoring (including integration of wireless and wired cable access) two categories. Incomplete statistics, 90% above are used in a wired network monitoring market monitor mode, but as network monitoring structures more complex, has become farther and farther, wireless monitoring slowly seize cable monitor market share. Wireless Monitor and cable monitoring quietly started a dark bucket, in this field in a war without gun smoke, who can better raise it? Network monitoring market developments will face ice double days of embarrassing situation.

Although traditional analog technology is still maintain a certain security market share, but analog security systems has been difficult to meet the diverse needs of users, with the advances in network technology and optimization of the network environment, IP security system to more efficiently handle the security information. As a new beginning of the era of network digital security, wireless video security brings a richer means of access and areas of application. Green City monitoring, bus, field monitoring, wireless monitoring technology can be used. Wireless monitoring is not perfect, is 3G wireless monitoring of market share far below cable monitoring also has also causes: first 3G wireless monitoring high of using costs makes many people are cannot accept; second 3G network bandwidth is bound its development causes one, wireless monitoring cannot provides HD picture quality; also used H.264 video compression technology solution has HD image monitoring problem, but in data compression upload in the still has distortion phenomenon. In view of this, wireless monitoring now mostly unable to bear the heavy responsibility of network monitoring.

Panoramic view of the security monitoring market developments, HD is the inevitable trend monitoring developments. Given the current 3G wireless network does not meet the demands of high definition, so most important fiber is the network monitoring. Optical fiber with high transmission bandwidth, capacity, free from electromagnetic interference, under the influence of the external environment is small, and many other advantages, in monitoring system of optical fiber can transmit all signals required distances can reach hundreds of kilometers. In recent years due to the rapid development of optical fiber communication technology, significantly reduce the cost of the optical fiber monitoring system, optical fiber and optical transceiver application in monitoring system more and more popular. According to an engineering friend revealed that currently dominated by cable monitor network monitoring engineering, cable monitor stability, but data transmission packet, not have a large impact; and the image has no, wireless monitoring drop-frame means that the mosaic appears. Video surveillance is nothing more than to see is image quality, mosaic is absolutely indispensable.

Whether it is wireless cable monitor monitoring, their advantages are obvious; in order to respond to market developments, current 3G network promotion also makes cable monitoring conducive to an invincible position, but this could not explain the cable monitor can always lead the trend of network monitoring. According to the current market situation, network monitor is in a single cable network monitoring to complementarity of wired and wireless network monitoring period, and this period is based on sophisticated technology and mature market as the background. We also have reason to believe that network monitor ice fire two days is only temporary, as technology advances, wireless network monitoring may also be future monitoring in the United States.
