10 applications Revelation of network Video surveillance

    

IP monitoring solutions has long been a number of changes around the network video surveillance of some misconceptions.

What is IP monitoring ?

IP is the Internet Protocol (Internet Protocol) acronym, it is through computer networks exchange of one of the most common agreement. IP monitoring solution is through cable or wireless IP networks to video information to digital form for transmission. As long as it is to reach the local network will be able to achieve on video surveillance and recording, and that such monitoring can also many other types of systems perfect combination.

According to industry analysts JP Freeman and Co., Inc., Analysis, only the United States to install the cameras have simulated 2,000 million units. This 20 million in Taichung, Taiwan is more than 15 million sold in 2002.  analog camera sales in the background, gradually came to the surface and the rapid development of next-generation products - the network camera. To see its development momentum, it is not hard to see the brilliant prospects with the idea of the number of the progressive enjoys popular support in the near future, it will replace analog products.

Network camera is a direct link to the new generation IP network products, so that remote users can watch video on the network, storage and collection of information to an analysis of the images to take corresponding measures. Network cameras are expected in 2007 will account for half the market share, to 2005, the global network video market is expected to reach 700 million to 90 million dollars.

Whether the camera is separate from the network composed of solutions, or from analog video camera and video server component of the solution, or a mixture of the two solutions, IP monitoring have been proved to be a very attractive Solution. In a growing number of the original application in the industry, this revolutionary technology is gradually replacing traditional monitoring systems, to improve security while further reducing costs, and in many new application areas, it is the first Once used, and therefore create and inspire a lot of new markets.

It is precisely because of its system scalability, IP monitoring gradually consolidate its existing surveillance and remote monitoring of the status of industry, but also has accelerated in the application of other emerging industries, including:
Education: remote monitoring of the school playground, corridors, halls and classrooms, including the monitoring of some buildings;

Transportation: remote monitoring station, railway tracks, highway and airport security;

Bank: Bank applied to all the branches or ATM machines in the streets, set up under the alternative means of traditional security surveillance;

Government: security and surveillance applications, often integrated into the existing system;

Shopping centres: the major supermarket branches to carry out safety monitoring and remote management to facilitate the rapid and efficient management;

Industry: the production line, logistics departments, the Treasury storage systems to monitor and improve the safety of the plant.

Why the misunderstanding? IP monitoring ?

Any new technologies emerge and followed the promotion, there will be a period of the market are not suited period, also known as market education period. Some of the more complex new technologies with existing technology or opened more distance, then this market is the more education a long time period. During this stage to the market, must be taken step-by-step means of the defect gradually built up the knowledge structure, should not have to make up for misleading the market. Only in this way can bring some wrong concepts and eliminate some confusion out.

No doubt, IP monitoring technology is a highly complex new technologies, in particular part of it inside the IP  traditional security concept to a real increase in the IT sector. In this sense, new technology and the market environment is faced with both opportunities and challenges of the situation. In fact, you will see, IP monitoring the face of the DVR is a direct competitor products. DVR for everyone to create the illusion is to let people mistakenly believe that DVR technology has on behalf of the market's most mature technology. Let us face of the bar. Why should analysis ? Because from top to bottom, from manufacturers to system integrators to end users, seems to have a DVR products almost fanatical interest. And we will use to explain your professional reveal the mystery of the one.

Revelation # 1: DVR is the best and the greatest CCTV security technology.

Fact: Some people think that not only drive digital video recorders (DVR) is the latest best technology, but also people think that DVR is already all-digital network technology - in fact, it is not.

DVR with the traditional video cassette recorders (VCR) contrast does have many advantages which, for example: There is no need to replace tapes and coherent image and ensure quick search function. But you still could not escape those cumbersome analog video cables, which will greatly reduce the quality of the image, but also the entire system down prices is also quite high. IP monitoring and on the DVR with all the advantages but also more DVR does not have the advantage.

Scalability. IP DVR did not control, such as a 16-way restrictions, can be expanded to a capacity of 1,000 Taiwan. IP surveillance can provide unlimited real-time-frame-rate user-selectable output.

More cost-effective infrastructure: the majority of existing equipment by twisted pair access, which is monitoring IP provided a good preparations, simply access network lines can easily get everything. Because all the data, video, voice and other network through the line for the transmission and management.

Remote control: all the video information, whether it is real-time or have been recorded, can be anywhere in the world without access to safe.

Intelligent camera: dynamic monitoring, emergency management, alarm equipment input, output delay, the log management and other built-in feature allows the camera can be intelligent choice when the information given to those who send and, even in what frame-rate and Resolution submitted will have the option.

Lower system cost: IP monitoring system is now installed in all the most economical choice. It is based on open standard network protocol, which it compared to the advantages of the DVR highlighted. You need to store image information ? Is only a matter of much hard drive. And it is simple to install and maintain a simple but far DVR is unparalleled.

DVR is not a final solution, that it is the CCTV monitoring technology on the road ahead seems to be a milestone in a more appropriate more. With the DVR market to a greater awareness, people will gradually realize that DVR is a kind of outdated technology, the narrow nature of its system so that it will gradually withdraw from the stage of history, and IP monitoring technology as superior to the DVR will also be gradually Be recognized. This is two distinct technologies, the market has begun to gradually understand this point.

Revelation # 2: IP technology is not yet a mature technology. If it has a mature, then it should have long occupied the market.

Fact: This question is more touch on some of the security market structure and on the purchasing habits of users problems, solutions and IP monitoring the performance and reliability has nothing to do.

IP surveillance is a relatively new technology, which currently has a strong competitor, is the DVR. Many people will want to bring their existing equipment retained, it is quite common people a conservative mentality, and the DVR gave the customer seems to be not such a waste of both the false impression that investment. We have to say that this is very natural. And this is the appropriate, IP technology as a new digital concept, but also need time to instil the idea that this system integrators, consulting service providers, where the hearts of the people to gradually overcome the inherent traditional concept. I believe we still remember Word word-processing procedures to replace the traditional WPS word processing procedures is how long before the matter, it is not a long time ? VCR video cassette was replaced by the latest DVD is the matter of how long it ? This shows that the technology gap is the need in time to overcome.

In fact, IP monitoring solutions do more and more cases, system integrators, the number grew rapidly. We believe that the near future, the market will recognize the superiority of IP monitoring, then we will see a lot of demand for emerging.

You might think that we have such a persuasive enough argument, then OK, just look at these giants such as IBM, Cisco and Proxim are in the near future into their network monitoring the area, you probably understand the direction of the market.

Revelation # 3: IP technology can not meet the needs of enterprise-class applications.

Fact: the installation of the project is, the higher the user's needs, the more they are able to highlight the advantages of IP monitoring, IP monitoring has proved to be a very competitive, very attractive brand new concept. In fact, the IP monitoring of the many advantages, scalability is its biggest advantage, but also high-end customers most valued point. Received 200 to 300 such orders to us is a very normal thing. Therefore, such an error is very easy to correct: IP monitoring will certainly be able to meet the enterprise-class applications. In fact, we have received an increasing number of government and the airport control orders, they agreed that IP surveillance is the best framework for this concept of change does is just 12 months only. This seems to point to what it shows.

Revelation # 4: network simulation video images of less than clear.

Fact: high-quality network cameras also can be simulated and comparable to the camera image sensor (CCD) and the lens. Moreover, the analog cameras and video servers will be able to integrate analog video cameras to collect information directly to the network transmission. High-quality network camera is for professional use, it must function with a simple low-end Web camera separate.

Moreover, as technology development, network cameras and IP monitoring technology can achieve megapixels of resolution, and analog camera due to its technical limitations, can only reach up to 40,000 pixels of resolution.

Revelation # 5: Network cameras compared to analog cameras are more expensive, IP monitoring too expensive.

Fact: on price alone, the network cameras are expensive than analog cameras to. But you should also see that it is the function of analog cameras unparalleled, analog digital, image compression and transmission intelligent control. Based on the DVR and the structure of the monitoring system of all charges comparison, IP monitoring cheaper than it should. The simulation system, are not you buy a DVR onlу, you would also like to buy many related equipment such as a large number of analog video cables. Moreover, if you want to achieve PTZ control, it also requires the laying of many other video cables, and features in IP PTZ control is still in the realization of the line through the Internet, does not require additional cables.

In 2002, has done a 300 network camera projects. This is a safe and high frame-rate record of demanding projects. Down the cost of this project is 800,000 U.S. dollars, an average of 2,700 dollars each way. In order to achieve the same function, DVR monitoring system would use 1.8 million U.S. dollars, an average of 6,000 dollars each way - than the cost of IP monitoring to more than twice as expensive.
Revelation # 6: I now installed the monitoring system is analog, it seems that I do not have access to IP surveillance, I only need to buy a DVR it.

Fact: Perhaps DVR providers want people to think that it is, in fact, the video server technology development has been to bridge the analog and digital monitoring and control seemingly insurmountable divide. Just received a video camera to simulate the server, you can simulate the camera to the acquisition of the video signal into digital signal compression on the network after the transfer. In other words, the video server to analog cameras with a network camera functions. In fact, most of the original analog monitoring system already has the users, they are more inclined to choose this way to build their own IP monitoring system, or network cameras and video servers composed of a mixed IP monitoring system. In short, your existing analog control system will not prevent you from monitoring the pace towards IP.

Revelation # 7: If all the video information through the network to transmit, it will not lead to network congestion or even the collapse of the network, so that it is not a mature technology.

Fact: If only a small number of monitoring points, then the existing Fast Ethernet (100 Mbit) to meet the demand for bandwidth transmission. Users can compression ratio and frame-rate adjustment from the line bandwidth. If the number of monitoring points is the case, we suggest that you might want to lay a dedicated line network. Mass Transit Railway and this is quite similar to the track - once the existing lines become congested, will have to track some new lines to ease the tension in the lines. Moreover, the large-scale enterprise applications, the local network is usually Gigabit LAN, the use of switches and routers, the network can be divided into different network segment.

Moreover, the intelligent network camera function can trigger events, dynamic testing and preset conditions, such as time to choose to send video frame rate. And the need for transmission of video information will not be too much, almost 10 percent of the time required to transmit information, 90 percent of the time have no information on the network video transmission.

Revelation # 8: Internet video transmission seems to be enough security.

Fact: While the initial network is designed to enable the public enough information, however, as long as the correct use of security means, such as firewall, VPN, or password protection technology, it also can be used to transfer some highly sensitive information. In fact, many banks and some financial institutions are using networks to handle a number of global financial matters. There is no doubt that for security surveillance and remote monitoring areas, it certainly is a reliable medium. And compared with digital monitoring and control simulation of the confidentiality of all but the more, it is almost no privacy. Anyone can see the simulation system under the so-called security information, and even tamper with this information, resulting in huge losses. IP monitoring and definitely will not happen on such a thing.

Revelation # 9: If a network congestion or even a sudden Duandiao, IP monitoring on an instant collapse, so that it is not reliable.

Facts: IP network architecture in the 1960s and early 1970s, development, to provide redundant backup feature has been a tremendous demand. Development Today, all kinds of storage servers, network switches and routers have been the optional provision of such earlier backup. Storage Server function is to ensure that offline after the call for information, application backup power supplies, hot-swappable RAID disk, fault-tolerant storage and dual-card can help achieve redundant backup. Although a small network structure may not need all these complex security measures, choose a high-quality IT components is in any case than the traditional CCTV solutions in the VCR or DVR to be much more reliable, but the problem in time DVR also addressed urgently than the much more time-saving solution.

Revelation # 10: IP surveillance is good, but it seems we still have some time from the distance, at least for five years.

Facts: that it is not to monitor the application of IP is all the times it seems that the crux of the problem! Let us use the specific data to illustrate this. Since 1996 launched its first network camera has been successfully sold and installed 200,000 network cameras, and the number is increasing rapidly year by year, fully shows that people on IP surveillance is also in the interest of increasing. Because people gradually found, whether it is cost-effective or reliable or from any other point of view, IP monitoring both have proved to be also applicable to the current focus on the future of mature solutions.

Here, we opened a large number of IP monitoring has been around since the various errors and error, hoping that people really can see the IP monitoring a highly scalable, effective and efficient use of the existing network of mature solutions.
