Now, security monitoring is no longer limited to the analog monitoring of video lines and control lines, but more to the digital, network, and intelligent direction. With technical advantages and development potential, IP network monitoring has been recognized by the industry as the main trend of the development of security systems. On the one hand, it is an increasingly large market demand. On the other hand, the “three-in-one†technology, especially the maturing of networked technologies, and the increasingly close linkage between security monitoring systems and computers, networks, exchanges, storage, etc. The security industry has entered the IT era irresistibly.
Entering the IT era, more security products are integrated and the security system management is more simple and convenient. The future security platform will be embedded into the entire IT system as an element, although security systems will be very small. "But the entire industry application will be "big". The integration of security industry and IT will make the integration of security faster.
Integration is the trend of integration into inevitable security systems including television monitoring, perimeter prevention, burglar alarm, access control, vehicle management systems, etc. These subsystems have been widely used, but the current status of most security system applications is: each subsystem mutual Separation, performance in the wiring, equipment, system platforms, business management and other aspects. Each security subsystem exists physically and electrically independently, with different cabling, different existing architectures, and different signal types. If there are several subsystems at the same time, even if there are occasional interactions between the subsystems, it is limited to a small amount of signal exchanges at the lowest physical level, and the subsystems are essentially “the sound of chickens and dogs, and the old dead are not comingâ€. This kind of subsystem relationship will certainly complicate the entire security system and lead to confusion in management. The future maintenance will also be quite difficult.
As network technology, video analysis technology, communication technology, information processing technology, and wireless technology are becoming more and more mature in the field of security, large integration of security subsystems has become possible, which not only reduces the cost of wiring and equipment, but also enhances the functions. The management platform facilitates operations and unified management, improves efficiency, and makes the system more user-friendly. At the same time, the traditional regional segmentation boundaries of security systems will also gradually fade, followed by more extensive integration and large sharing of information and data.
Since the development of the security system, many sophisticated technologies have been introduced in the traditional industries, such as IT industry network technology, communication industry transmission technology, conversation technology, multimedia codec technology, video processing technology in the field of photography, and digital interfaces in broadcasting. Technology, etc., has now begun to appear in various applications of technology convergence, forming a series of product system solutions based on network, intelligent, digital, high-definition. With the wide application of technologies such as IT and communication technologies in security systems, the integration of security systems and IT systems has become possible. For example, business systems embedded in security applications in various industries have started, such as chain stores, power substations, and Business processing video systems such as transportation, finance, electronic proctoring, and environmental protection monitoring, as well as cross-region and decentralized networking projects, such as the most representative emergency command systems and burglar alarm platforms, are becoming more and more integrated with IT and communication systems. Industry processing system. Security IT or IT security, in fact, security has begun to integrate into the multimedia information.
The mutual influence of IT and security technology is based on historical reasons such as application requirements and technological development. Although the traditional security system technology is very mature, its basic architecture and composition are not related to IT technology. And now IP monitors its digital video streams for transmission and storage over the network. Its data carriers are networks, servers, and storage devices. Without exception, they are part of the IT infrastructure. Therefore, the use of IT technology to design the infrastructure of security systems is unavoidable for current security. Therefore, fully understanding the integration trend of security and IT technology will greatly benefit the development of security technologies and applications in the future. However, it can also be seen that security technology and IT technology actually affect each other.
The development of digital video surveillance technology has always been affected by IT technology, especially the impact of network technology. For example, the earlier MJEPG was limited to the network transmission bandwidth, followed by MPEG2, MPEG4 and even today's H. 264 These compression algorithms are suitable for low bandwidth transmission; the application requirements of high-definition video technology and streaming media in video surveillance have also stimulated the continuous updating of high-speed network technologies and products. The bandwidth of network products has gradually increased from 100 megabytes until now. 10G network; video storage has evolved from the first inexpensive tape drive to today's network storage, and its technology has always been affected by the development of IT technology.
In fact, IT companies have long existed in the security market. With the advancement of digitalization, the security market has long been not a pure security market. In the security industry, chip technology, video compression algorithms and other technologies have gone far beyond the traditional security technology, intelligent and networked security products, video surveillance network management and secure storage of video information, but also with security technology To the high-tech field, and to more, newer IT high-tech areas. The needs of the security industry continue to promote the update of IT technology.
At present, the composition of IT systems is also affecting the development of the security industry. Because the IT industry has a consistent development direction and the use of common industry rules, the development of IT technology has always occupied the forefront of technological development. Its experience is to provide users with products and systems that are universal, standardized, functionally perfect, highly available, and highly compatible, and establish a unified method and standard for operation and maintenance. The security industry is still unable to meet the standards of the IT industry for various reasons. However, with the development of the integration of the two, IT technology and its constituent methods have a clear effect on the development of security. If all manufacturers can not reach an agreement at the application level at this stage, at least a unified standard should be formed from the product architecture, engineering design, and operation and maintenance model, so that the level of the entire industry will rise to another level.
IT has truly promoted the standardization and standardization of the security industry. In the security industry, integrating different types of systems is constantly being applied to the real world. To achieve the effect of integration, the data sharing platform is an important part, and the openness of the subsystem is also very necessary. At present, the security industry is on the way. The most important thing is the open platform. IT technology with strong organization and control capabilities will be the protagonist of the platform. If security is well integrated with IT technology and its methods, it can not only improve the working environment in which the security industry is engaged, but also simplify the complex system architecture and effectively reduce the overall cost of ownership of the users, especially the cost of system operation and maintenance. At the same time, the role of security information data can be fully exploited to increase the value of security systems.
With the accelerated pace of IT in the security industry, the traditional security industry will face significant changes in capital composition, talent structure, and service concepts. Compared with the previous situation in which security industry entry barriers were low and the level of technical requirements was low, the IT industry in the security industry will also make the industry more standardized and standardized. In this process, IT companies can gain more cooperation with security companies in terms of capital, technology and sales. Based on the above, it can be seen that due to the unstoppable integration of security and IT, the impact of IT on the development of security will increase. As part of the physical security precautions, security systems will eventually integrate with information security as part of the IT industry. The convergence of the two industries finally manifests itself in the widespread application of IT technology in security systems and the penetration of security products and IT products in distribution channels.
Integration and integration provide technical support. In essence, IT and security are all dealing with information, and they are all moving in a direction that spans time and space. How do the technologies of these two industries achieve mutual complementarity and gradually become unified.
The current security is actually changing quietly in terms of business. In terms of video surveillance, the combination of digital and analog methods and traditional analog methods are increasing. IP technology is flooding into the video surveillance system, supporting the network It is becoming a core business requirement for monitoring.
Looking at today, video surveillance or security services in all walks of life have become more and more clearly and universally presented as networking requirements. Under the penetration of IP, the security field has already established a foundation for IT interoperability standards in terms of technology. . It can be predicted that within a few years, it will no longer be an independent two major field, but a new IT that integrates security, IT technology and business.
So, how can we effectively build multi-domain network monitoring and realize video surveillance image information sharing? As far as the construction of previous monitoring systems is concerned, the video surveillance equipment used by various regions, units, and subsystems is from different manufacturers, and the technical architecture and standards adopted are also different. These differences include not only the control signaling of the device but also the encoding of video images and the storage of images. Due to the independent construction of subsystems and the adoption of different technologies and standards, the systems cannot be interconnected and interoperable, but the image storage is scattered and the storage format is not uniform, which makes image sharing difficult and the data cannot be comprehensively utilized. In order to really apply it, it must be networked first, and networking should have corresponding standards.
According to the “Safe City†project of a domestic province where the network monitoring is more mature, the main idea of ​​formulating the standard is: through the gateway, the differences between various manufacturers and equipment are shielded, which not only solves the intercommunication problem, but also does not fall into various sub-groups. The internal details of the system solved the key issues of the current monitoring industry, respected the reality, and left room for various manufacturers to play.
The above-mentioned standards for a provincial networked application introduced a networking unit, which is responsible for the transmission and conversion of control commands and video data in a networking process. As the language of communication between platforms is defined, the basic requirements for video surveillance, information sharing, and daily operations are defined as a language that everyone can understand. As for the various manufacturers and industries, how to operate and achieve no intervention. In this way, taking into account the status quo and the future, only exports and functions are required, and internal problems within the region can be solved by themselves. Through this kind of networked video surveillance platform, it can effectively solve the large-scale concurrency problem of video resources, and provide an optimized distribution solution for front-end control rights, thereby enhancing system management and reliability.
In November 2008, ONVIF organizations initiated by Axis, Sony and Bosch currently have close to 40 members. Among them, there are 10 senior members. In addition to three startup companies, Panasonic, Samsung, Cisco and other famous brands are among them. Hikvision is a domestic ONVIF senior member. The establishment of this organization is to promote the application of network video in the security market through global open interface standards. This interface standard will ensure the interoperability of network video products produced by different manufacturers. The ONVIF standard will define a common protocol for information exchange between network video devices, including device search, real-time video, audio, metadata, and control information.
Complementarity and cooperation to create a win-win situation is undeniable, IT companies have strong total package capabilities, and weak systems such as office automation, integrated cabling, and network systems are related to their IT majors, and they have a comprehensive range of technologies to manage and coordinate subsystems at a certain height. Technical relations. However, the security system has its own rules, such as qualifications, regulations, standards, construction, approval, and acceptance, which are both technical and non-technical factors.
From the perspective of Party A, although some projects will put the security system into the low-power package, in some important industries and units, the security system still needs to be individually tendered or approved. More and more industries now attach great importance to the security system, and even adopt a "security-one-vote veto system," which is directly controlled by the security department or the person in charge and vice chief level. The security department is responsible and the IT department assists.
In view of the above understanding, IT contractors and security engineering companies have gradually cultivated a tacit understanding, each with a field of hard work, forming a division of labor model of IT total package, security subcontracting. With the introduction of the latest qualification certification conditions in 2010, due to the provision of “no artificial separation of security projects, no subcontracting, subcontracting of security projectsâ€, this mode of IT general package security subcontracting will depend more on Party A. The importance of security.
Although the international IT giants can acquire some excellent security companies, on the other hand, security companies can also use their talents as a platform to take advantage of strategic alliances to complement each other's resources and integrate resources. This is also a preferred way to save costs and expand the market. The attraction of IT and security composite talents and paying more attention to follow-up services is also a competitive means for enterprises to advance with the times. Therefore, traditional security companies do not need to worry too much about the entry of IT companies.
The good market opportunities in the security industry and the need for IT technology have shown the opportunity of IT companies, but the phrase "interlaced as if separated by mountains" is equally valid for IT companies entering the security industry. Entering the security industry, IT companies have similar challenges.
IT companies entering the security industry are faced with being familiar with the security industry and being familiar with security users. Many traditional security companies worry that IT companies will impact the market. IT companies entering the security industry have a process of entering, familiarizing with and even developing their skills. This will take some time. IT companies have many new technologies and products, but the channel advantage of the security industry is still controlled by security personnel.
The sales model and channel system of security products have become a major weakness for IT companies to enter the security industry. More IT products are faced by the ultimate consumer, and security products are still industrial products before they are used in large-scale home use. Usually, products are purchased, installed and commissioned. Most of the work is done by contractors. Completed, the product from the factory to the use, there are many links, so the local sales and service providers are very important, so in many cases the product sales need to participate in the project's operation. This determines the sales of security products, who can grasp customer resources, who will win.
Product-oriented differences also affect the development of IT companies in the security market. Due to the relatively long development time of the IT industry, the product's absolute standardization design is very mature, and the number of products sold is also very large. The products are more inclined to be designed by the manufacturers, and the users buy what they are, and the majority are factory price-oriented. With the rapid development of the security industry in recent years, products emerge in an endless stream, the product differentiation is relatively large, homogenization of similar products of different brands is more serious, product design often appears in the form of solutions, mostly oriented to customer needs, Security products have greater attributes as value-added products. Users are most concerned about the value of security products. After the products are purchased, they can be used after installation, debugging, etc., which in turn embodies the added value of sales or engineering companies.
The lack of product-oriented inertia and channel advantages make it difficult for IT vendors to play a decisive role in promoting the IT revolution in the security industry. If an IT company wants to establish its own security business in a diversified way with the advantage of IT technology and competes with security companies, the effectiveness may be less effective.
Conclusion Since the sales channels of the security market have their own particularities, using traditional channel advantages of security companies to penetrate the market quickly is also a good way for IT companies to enter the security industry. IT companies help traditional security companies improve IT technology capabilities, and security companies help IT companies increase brand influence. Together, they can jointly create a big piece of the security market. The best mode for IT companies to enter the security industry, although it has been agreed upon by IT companies and traditional security industry, how effective it can be, remains to be proved.
Entering the IT era, more security products are integrated and the security system management is more simple and convenient. The future security platform will be embedded into the entire IT system as an element, although security systems will be very small. "But the entire industry application will be "big".
