Network video monitoring about ten

    

IP monitoring solution changes some long network video monitoring around some of the wrong idea.
 
 What is the IP monitor?
 IP is through the computer network communication of the most commonly used one of the agreement. IP monitoring solution is through wired and wireless IP network video information in digital form. As network can reach can achieve video monitor and record, and the monitoring can also with many other types of system of perfect union.
 According to industry analysts J.P. Freeman and Co, Inc. In the United States alone, analysis and simulation of the installation of cameras have 2,000 sets. But in this $20 million, more than 15 million in taichung was sold in 2002. In analog camera, under the background of the adoration of sales is gradually emerging and rapid development of a new generation of products, network video camera. Watch it momentum of development, it is not difficult to foresee a bright future of it, With the concept of digital gradually thorough popular feeling, in the near future, it will replace simulation products.
 Network camera is directly connected to the IP network of a new generation of products, the user can realize remote video on the Internet to watch, storage and collected information on image analysis corresponding measures.
 Whether by network composed of single camera solution, or add video camera by simulating the server components solutions, or a mixture of both is composed of solutions, IP monitoring has been proved to be an attractive solution.
 
 Why have the misunderstanding of IP monitor?
 Any kind of new technology and followed the promotion, there will be a time to market, also called education market. Some of the new technology of complex or with the existing technology of the great distance open education market, so that the longer period. In this section, we must take to stage a gradual means the defect of knowledge structure gradually building up, not some market misleading. As such, you can put some misconceptions and eliminate some confuse.
 
 Error: DVR is currently the best CCTV security technology
 Fact: not only someone think digital hard disk video recorder (DVR) is the latest and greatest technology, but also people mistakenly DVR is already full digital network technology.
 With the traditional video tapes DVR contrast (VCR) have many advantages, but I still can't get away from the complicated analog video cables, they will greatly reduce the quality of images, and the price is rather expensive system down. But the IP monitoring had all the advantages and DVR DVR don't have more advantages.
 Scalability: no DVR as IP monitoring and restrictions, such as can be extended from a capacity of thousands.
 More economic efficient infrastructure: most of the existing equipment by twisted-pair access, it is the IP monitoring provides a good preparation, only some can easily access to fix everything. Because of all the data, video, sound and the other is through the network to undertake transmission and management.
 Remote control: all the video information, whether still have recorded in real-time, can safely in any part of the world.
 Intelligent video surveillance and dynamic: emergencies alarm equipment, input, output, log management delay and other built-in functions allow cameras can intelligent choice when the information sent out and gave what people, even in what frame rate and send out the resolution can choose.
 Low cost: the system more IP monitoring system is currently all installation way most economical choice. It is based on open standards, which makes the network protocol DVR advantages compared to it to. The need to store image information? Just a hard problem. But it is concise installation and maintenance of the simple but far is DVR incomparable.
 DVR and is not a final solution, says it is CCTV surveillance techniques on the road of advance a milestone seems more appropriate. Along with the further understanding of the market DVR, people will gradually realize DVR is an outdated technology, the system will make it the narrow-mindedness of the stage of history, and gradually withdraw IP monitoring technology is superior in DVR and will gradually be people realize. This is two kinds of disparate technologies, the market has been gradually began to realize it.
 
 Error: IP technology still not mature, if it has matured, it should occupy the market
 Fact: this question is more touches on security market structure and some problems, the user buying habits and IP monitoring solution performance and reliability.
 IP monitoring is a relatively new technology, it has a strong competitors, DVR. Many people will want to take them to the existing equipment, it is preserved the common people, and a conservative psychology DVR gave it a seems to be not wasting both investment illusion. We had to say, this is very natural. And the corresponding IP technology, as a kind of brand-new concept of digital time, still need to instill this concept to the system integrators, consulting services, to overcome the traditional concept in people's hearts. Believe you also remember the Word Word processing program instead of traditional WPS word-processing program is long ago, not for a long time? The latest video tape by replacing the VCR DVR and how long? Therefore, the technology is needed to divide over time to overcome.
 In fact, IP monitoring solution of the cases, and more and more rapid growth in the number of system integration. We believe in the near future, the market will realize the superiority of monitoring, IP, we will see a lot of demand.
 You might feel like we not persuasive, ok, just look at these giants like IBM, Cisco and Proxim are in recent foray into network monitoring field in succession, you might understand market orientation.
 
 Error: cannot satisfy the IP technology enterprise application
 Fact: the installation project, the greater the user's demand is higher, the more he can highlight IP monitoring, IP monitoring has been proved to be a very competitive, very attractive brand-new concept. In fact, in many of the advantages of the IP monitoring, extensibility is its biggest advantage is the most important point of high-end users. So this is a deterrent to easily rectified: IP monitoring can satisfy enterprise applications. In fact, we received more and more government and the airport, they agreed that orders for monitoring and control is the best structure IP, the idea of change has just 12 months. This seems to be enough to explain something.
 
 Error: 4 network video image than analog clear
 Fact: the real-time monitoring network video effects and replays effect is completely consistent, and, of course, the digital image processing, compressed by than before the treatment effect of the analog signal slightly some losses. While the traditional hard disk video recorder, monitoring and playback effect is abhorrent, monitoring in due course of direct signal, the effect is very good, and playback effect also passed compression, the effect of different manufacturers use depends on good compression techniques.
 And, with the development of technology, network video monitoring technique can achieve and IP mega-pixel camera, and simulated the resolution because of its technical limitations, only can achieve 4 million pixels resolution.
 
 Error: network video camera to expensive than analog IP monitoring, too expensive
 Fact: the price list, network video camera is expensive than analog. But you should also see its function is simulated camera incomparable, digital and analog signal transmission and intelligent control of image compression. Based on the structure of the monitoring system of DVR comparison, all expenses than it cheaper IP monitoring. For simulation system, not you bought a DVR just enticingly, you still buy many related equipment, such as a video simulation of cables. But, if you want to achieve PTZ control, also need other video cables laid many PTZ function, realization of monitoring in the IP network line is still through, do not need additional cable.
 
 Error: now I install monitoring system, simulation is no IP monitoring
 Fact: maybe DVR provider wants people to believe it, but in fact, the development of video server technology has been simulated bridge between digital control and monitoring seemingly impassable gulf. The video camera received by simulating the server, you can simulate the video camera to convert digital signal compression signal transmission in Internet. Namely, video camera with a server to simulate the function of network video camera. In fact, the most original have users of monitoring system simulation, they tend to choose the way to build their own IP network monitor system, or video camera and the server is composed of hybrid IP monitoring system. Anyhow, your existing analog monitoring system will stop the step towards your IP monitoring.
 
 Error: if all the seven video information through the network transmission, it did not cause the network congestion and even collapse
 Fact: if only a few words, so the existing monitoring 100Mbit fast Ethernet () can satisfy the requirement. Transmission bandwidth Users can according to the compression ratio, frame rate to adjust bandwidth. If multiple monitoring, we suggest you had better laid a specialized network lines. The railway transportation is quite with similar, once the existing urban rail traffic congestion, have become new rail line to alleviate some of the tension of the line. And, for large enterprise applications, the local network is usually gigabit levels, using the LAN switches and routers, can be divided into different network segments.
 The camera, network and intelligent function can according to the dynamic testing and event, preset time to choose whether to send conditions such as video. The video information transmission and need not too much, only 10% of the time needed to nearly 90 percent of the time, the transmission of information without any video information in network transmission.
 
 Error on the network transmission 8: video safe enough
 Fact: although the initial network aim is to make sufficient open information, however, as adopt correct safety means, such as firewalls, VPN or password protection technology, it can also be used to transfer some of the highly sensitive information. In fact, many Banks and financial institutions are used to deal with some of the global financial network. Undoubtedly, for safety surveillance and remote monitoring field, it must be a reliable medium. And digital control, monitoring the confidentiality of the simulation of the poor, it almost no privacy. Anyone can see simulation system of these so-called safety information, even to tamper with these information, caused great damage. But the IP monitoring wouldn't happen.
 
 9: if the misunderstanding of the network congestion and even suddenly, IP monitoring instantly break down, so that it is not reliable
 Fact: the IP network architecture in the 1960s and 1970s development, can provide redundancy backup function has been a great demand. Development today, all kinds of storage servers and network switch and optional router has always provide the same function of backup. Storage server functions is to ensure that after the call and convenient application material, backup power supply, heat exchanger, storage and RAID disk fault double nics can help realize redundancy backup function. Although a small network structure may not need all these complex safety measures, choose a high quality components of IT no matter how is better than the traditional CCTV solution to the VCR or more reliable DVR and problems in time of emergency than much time-saving DVR solutions.
 
 Error 10: IP monitoring is nice, but it looks like we have a period of time from the distance, at least have 5 years
 Fact: think now is less than the time seemed IP monitoring application is the crux of the problem! Let us use specific data to explain. Since 1996, launched the first paragraph network cameras, has been successfully installed 20 million sold and network cameras, and the number is rising rapidly in the year, people's interest is in IP monitoring. Because people discover, whether from the price or reliability or any other aspects, IP monitoring has been proved to be applied both current and future of mature solution.
 
 Here, we opened a lot around the IP monitoring has been mistakes and deterrent, hope people are able to see the IP monitoring really a highly scalable, effective and efficient use of the existing networks of mature solution.
