Video surveillance system based on IP has appeared in recent 10 years. In this period, IP monitoring solution with practical shattered long video surveillance network around some of the wrong idea.

1, what is the IP video monitoring (IP - Surveillance)?

InternetProtocol Internet protocol (IP is the abbreviation of), it is through the computer network and Internet communication is the most commonly used when an agreement. IP video monitoring system (also called network video monitoring system of digital video information can be), and through the wire or wireless IP network for transmission. This makes real-time monitoring and video functions can be extended to all have Internet connection, also make this kind of system can conveniently and other security system (such as access system, etc) seamless integration.

According to the famous industry analysts J.P.F reeman and analysis of the company in the United States alone, the installation of cameras have simulation of more than 2000 million. In the 2000 million, more than 15 million in taichung was sold in 2002. These digital camera to simulate the best-selling, but nonetheless, network video camera or from the market come to the fore, become the most rapid growth of video surveillance products. Direct access to the network video camera to IP network, and the other with network applications, users can effectively integrated in remote locations, through the internal network cameras or Internet in other one or more locations, storage and watch the video data real-time analysis. According to another well-known industry Co., Frost&Sullivan forecast analysis in 2005-2010, traditional CCTV products sales at an annual rate of only 10%, and market capacity will reach saturation in 2008, Over the network video product sales growth will reach about 40%, even in 2010 are still rising space. It is therefore not foresee, with digital ideas gradually thorough popular feeling, in the near future, it will replace simulation products.

IP monitoring solution can be entirely by thenetwork camera, also can add video camera by simulation, or is also server by a mixture of both. Regardless of which kind of form, using IP monitoring has been proved to be a kind of industry are extremely attractive solution. In numerous industry application, this revolutionary technologies is gradually replacing traditional monitoring system, in order to reduce the cost and improve the safety. In some applications, it is also used to create and stimulate began a new market.

Strong extensibility is IP monitoring system is one of the main advantage, this makes it was confirmed as an attractive technology, not only applicable to improve and perfect the existing video surveillance and remote monitoring system, and is suitable for some new industry applications, including:

Education: remote monitoring, school playground, corridor, the hall and the classroom building, also include some of the monitoring,

Traffic: remote monitoring station, railway, highway, airport, the safety,

Robert: main street bank branches of safety monitoring, control and monitoring and ATM,

Security and surveillance, government: integrated into the existing application, usually in the system,

Retail: used for security, and remote monitoring, effective management, simplified shops to improve work efficiency

Robert: used in industrial production, logistics system monitoring, warehouse and inventory management, etc

2, why would exist for IP monitoring technology of misunderstanding.

For any kind of a new technology, from its appears to have extensive application, will experience a market education stage. Some of the new technology, the original complicated technological and business model, then the market more entrenched education stage duration will grow more. In the process of knowledge on some faults and misunderstandings that is commonplace, it was also in this environment, some new techniques on wrong ideas and confuse will continually develop and spread.

In fact, IP monitoring technology is not a highly complex technology, but which belongs to the category of "IP" part of the traditional security concepts, and into a most traditional security professionals are very strange field - IT field. From this point, this new technique and its application of the new environment and inspire fear will lead to the support for the status quo. IP is formed a monitor direct competition with DVR, this kind of situation has brought a series of dispute, it is one of a recognized the challenge, this view is simulated with DVR technology video cameras monitoring system of the ultimate solution, so is the best video monitoring technology. Careful analysis, and it is easy to distinguish conclusion: first of all, current security industry from the manufacturer to engineering, system integrators, to end users and their institutions, all have known DVR and simulation technology, and for the camera into money, of course they are happy to see DVR become market dominant products to consolidate their vested interests. Secondly, the traditional security industry, and the inherent sealing technology, a private brand solutions to market within the prevalence of further against the "rumour" IP monitoring. In sharp contrast, IP monitoring solution integration from different suppliers of the best product and service, it is the result of end user's maximum profit, but the result with the current market environment and market expectations.

So far, we have learned about why the market has many misunderstandings in IP monitoring, and the preliminary discussion on the part of facts, IP monitoring in some markets next we will be on the wrong idea widely circulated to do further points.

IP video monitoring, about 10 misunderstanding

At present, there are many market on IP video monitoring technology of misunderstanding, here, we chose one of the 10 most common, and put them into two categories: unskilled and technology. We will firstly analyzes the non-technical related misunderstanding, and then further discusses those technologies related topics.

Misconception # 1: DVR is the latest and most powerful of the CCTV security technology

Truth: not only someone think digital hard disk video recorder (DVR) is the latest and greatest technology, but also people mistakenly DVR is fully digital and network technology, and actually, it isn't.

With the traditional cassette VCR (VCR), there are many advantages in DVR indeed, for example: without changing tape, consistent and quick search function image quality. But you still can't get away from the complicated analog video cables, they will reduce the image quality and increase the cost of the whole system. And not only possess IP monitor all have the advantage of DVR, but also has more advantages in DVR not, for example:

Scalability: IP monitoring system, no similar to that in every 16 DVR to expand the scale of road system, user can use the limit of time only a way from the system will be expanded to include a camera containing thousands of cameras. At the same time, it also enables users to freely choose any camera and frame rate, without any time or frame on the speed limit.

More economic efficient infrastructure, in many cases, the most original equipment users have through the IP network connection, thus building IP monitoring system without additional cabling work (cabling cost is usually CCTV system is one of the main construction cost. This kind of circumstance, the user data, video, audio, and other information will be the same network transmission and management through the system, thus the management work becomes more economic efficiency.

But the remote access: user can through wired and wireless network in the world, the safety of any one corner of the visit and control all the real-time video information, whether video recording down or has the video data.

Intelligent network video camera: built-in series intelligent function, including dynamic detection, incident handling, sensor input and output relays, date and time etc, these functions can be made according to the requirement of intelligent surveillance cameras, which can make decisions at the right time to correct the alarm information sent to correct recipient, and may, in accordance with specified frame rate and resolution of the time specified in the video information will be sent to the specified user.

Lower system construction cost: seeking proof, IP video monitoring system for many monitoring project is a more cost-effective. IP monitoring solution can use open and standardization of the network, server and storage devices, it allows users to make the suppliers from more choices, and more cost-effective solution DVR most users subjected to a single or a handful of suppliers. In addition to the hardware selection factors, IP monitoring system has lower installation and maintenance cost and higher performance advantage, all this clearly shows the IP monitoring system for the user to save considerable construction expenditure.

We can see that, like most people DVR not imagine that a final solution, but in the process of development of CCTV technology is one of the milestone. After the market further careful evaluation, find those who actually represents DVR obsolete, "black" type of solutions, and IP monitoring is soon proved to be superior to an update and DVR has more advantages of technology. In fact, IP monitoring system with DVR exists between the numerous difference, but the present market is just realize this.

Misconception # 2: IP technology is a mature technology. If it is more advantageous, why security solutions suppliers can't achieve more related sales?

Truth: it is a misunderstanding that has been reached, the problems in the greater extent with the security market is related to the structure and buying habits, and not with IP monitoring system performance and reliability.

IP monitoring is a relatively new technology, and many existing, powerful security companies are a direct competition with DVR solutions, they hope to their existing facing DVR solutions for protection is a very natural thing. In addition, for any kind of new technology and new thinking, to replace the original thinking mode and behavior patterns, must first in integrators, industry consultancy and other related industries influential institutions of constructing the relevant background and the necessary infrastructure, the preparation work requires some time to finish. Few people will remember that prevail in the typewriter, we had thought that machine work for us for word processing has completely enough, don't need those elves odd word processing software. Time is too long? So please consider again those old card type VCR (VCR), whether you are in for a long time it for now popular DVD player? Even you still in use it? Obviously, the old and new technology of alternating is needed some time to finish.

The truth is, behind the misunderstood by IP monitoring technology project quantity in the rapid growth in IP monitoring, system integrators and distributors in increasing. Before long, the security market will realize the superiority of monitoring technology IP, IP monitoring system will promote the rapid, also can have more infrastructure to support.

If you think the truth is not very persuasive, so let's look at some of the industry's giant treat IP monitoring attitude: IBM has entered the network security market, Cisco and Proxim also is full of IP video monitor market of guidance and education. Thus, I believe we no longer need more arguments.

Misconception # 3: IP monitoring solution can meet the practical application software security requirements.

Truth: the scale of the system, the higher the required performance, IP moniting solutions of competitive advantage is stronger.

The IP mentioned above summarizes the advantages of monitoring system, extensibility is widely considered the most prominent high-end clients of all of the advantages. Contains more than 200 to 300 Axis system for the cameras are some common project, some systems containing thousands of network video even. In these systems, some are used in some degree of safety requirements of very high application place, such as the international airport and prisons, etc. So it is easy to be misunderstood, seeking clarification proof IP monitoring system for enterprise-level safety can fully. Actually, we've seen some large government and video surveillance system application designated airport will IP monitoring solution as the preferred solution, but this phenomenon in one or two years ago has never seen.

Misconception # 4: network video image quality image quality good. No simulation

Truth: high performance networks with high-end camera used analog camera same quality image sensor (CCD) and optical components. In addition, by using video server can be simulated cameras or professional installation of simulation has been integrated into the IP camera convenient monitoring system. In comparison with analog video camera, network, must pay attention to the network video camera here refers to those used in video monitoring of professional level, rather than those used in products, video cameras, chat with the camera low-end function complete network cameras are not comparable.

In the near future, network video monitoring and IP technology will generally support million pixels resolution, which can provide super image quality. And will always be subject to analog camera NTSC/PAL standard, thus making the highest resolution is limited in about 40 million pixels.

Misconception # 5: network than analog video camera high cost, thus making the IP monitoring system of the construction cost is very expensive.

Truth: network camera price than the performance is high, the price of analog camera is because it integrates than analog camera more advanced features, such as information digitization, image compression and other intelligent characteristics, etc. If the overall cost of system hardware (including the camera, cable and video store, etc), you will find IP monitoring system based on the hardware cost and usually DVR monitoring system, hardware cost again considering system installation cost, so IP monitoring system is obvious advantage, because building based on IP infrastructures than the cost of building based on coaxial cable infrastructures a lot less. In addition, if needed, PTZ control simulation system must also conduct additional control circuit, and IP monitoring system the extra expenses. Ethernet power supply (concepts behind PoE, PoweroverEthernet) technology is IP monitoring system of another can effectively save construction cost advantages, this technology makes network cameras can play received through the same power and data, and work for the user can save the cost of equipment powered, and can and wiring uninterruptible power supply (UPS), further improve the reliability of the system.

Misunderstandings # 6: if has installed a lot of simulation, the user can't again video monitoring technology, using IP use only DVR.

Truth: perhaps DVR suppliers very much hope that this user, but the video server (VideoServer) technology is a misunderstanding on it were able to vigorously. Leading IP monitor suppliers' can provide users with mature video server products, and its cost is in reasonable range. Video server can be simulated video signals into digital network transmission through video camera, which will be transformed into a computer simulation with the basic function of network video camera. Most current IP monitoring system is shirt-sleeve the video networked servers via the simulation and the real meaning of video camera, existing network simulation system and equipment for users will adopt advanced IP monitoring technology bring any obstacles.

So far, we have been clarified some often heard about IP monitoring system of misunderstanding, they are related to the topic. Non-technical Next, let us to those technologies related to do a thorough analysis of the misunderstanding.

Misconception # 7: through all these video data transmission network will cause overload, so this technology network is actually did not.

Truth: a single network camera usually just 0.2 to occupy 2Mbps bandwidth, ZhanYongLiang depends on the bandwidth of the actual image compression levels, the image size and frame rate. If only a few sets, then existing network cameras have office network 100M video data transmission completely satisfy the requirements. For video cameras and contained more network server system, we suggest that the user to open special network video data. Like the railway transport, once the existing congestion, so just appear railway build some new tracks. For enterprise applications, its core network are usually can achieve in the current capacity, gigabit switches and routers, under the support of users can easily be network bandwidth resources, so as to retain video applications for bandwidth resources. In addition, still can use some special configuration, to ensure network cameras in integrated into the enterprise network when not occupy excessive bandwidth resources.

On the other hand, network video camera itself is an intelligent, it may, according to the different time, events or through the network to send to determine that the use of video frames and resolution. Therefore in most cases, the camera will only 10% of the time by sending the worth of video information records and archives, and the rest of the time, no 90% of any data through the network for transmission.

Misconception # 8: through the IP network video transmission important information is not safe.

Truth: although the Internet is mainly used to transfer some public information, but only by the correct network security measures (such as firewalls, VPN and password protection, etc.), it can also be used for some security requirements of high sensitivity. As is known to all, many Banks and financial institutions are often through the Internet in the global range of financial services, so for safety requirements relatively low video surveillance applications, the Internet is also can become a reliable bearing media. And the corresponding simulation is unable to use any safety monitoring system authentication mechanism, encryption, or anyone could easily get DaXian through the way of video information transmission lines, even can fake video error messages to the monitoring center monitor video monitoring system, thus completely failure (as many movie mythology). But this kind of situation in effective safety measures adopted in the IP monitoring system is not possible.

Misconception # 9: IP monitoring technology, high reliability, no other technology, for example, in the network, the system will be paralyzed cannot continue to work.

Truth: early in the 1960s, IP network infrastructures were first developed, how to ensure the redundancy network has been building IP network as the primary factors must be considered. The IP network technology development today, network of transmission lines, application servers, storage equipment and switching and routing device can configure spare resources, in the main link or main equipment malfunction, standby equipment can still maintain the link and the normal operation of the system. Based on IP network system, a storage device can be deployed in remote locations, the server can use safety of power supply system, can alternate using support hot pull the plug drives, since the recovery memory RAID and various measures to double network to ensure reliability. Although the network system for small, may not be adopted above all safety measures, but based on the quality of the components IT anyway solutions than traditional CCTV solution is more reliable and DVR. In addition, as a result of the standard of server and network equipment for IP monitoring system fault equipment needed replacement cost and time will be closed DVR system is much lower.

Misconception # 10: IP monitoring is still at least 5 years universal time.

Truth: it is undoubtedly one of the biggest misunderstanding! Axis since 1996 the world's first since the camera, network in the world has already sold more than 50 million of these so-called "future" products on the market, at the same time, the monitoring system for IP and increasing demand. Whether from the overall cost, the overall system performance, reliability, or in other aspects of standard to measure, IP monitoring system has been proved mature solutions belong to now. With IP monitoring technology improvement and popularization, IP monitoring system in the future will also become the security market forces.
