The standardization and consistency of security IT infrastructure become hot spots

The development of new security technologies can be described with each passing day. From the point of view of video surveillance systems, digital video surveillance products rely on the development of electronic chip technology and information technology is also constantly innovating, thus the image of the surveillance system is clearer, the signal transmission is more stable, and the product functions are more abundant. After the unexpected new product and new technology application, it also brings about how to re-evaluate the existing application system from the perspective of system architecture, and how to build a more efficient and reliable infrastructure, so that new products and technologies can be brought into full play. The role of the problem.

In fact, at present in the construction of security systems in China, the construction of its infrastructure has not received enough attention. The reason is to ignore the use of IT technology and its methodology to build the system's infrastructure. For example, IP video streams are transmitted through the network for transmission or simultaneously transmitted to the control center to meet the real-time monitoring needs of users. The carriers of these security data: networks, servers, storage devices, etc., without exception, are all IT infrastructures. a part of. Then using IT technology and its methodology to design the infrastructure of the security system is inevitable for security. Therefore, for security practitioners, fully understanding the integration trend of security and IT technology is of great benefit to the development of security technology and application in the future.

Security and IT technologies affect each other The development of digital video surveillance technology has always been affected by IT technology, especially affected by the development of network technology. The earliest video compression MJEPG was limited to network transmission, followed by MPEG2, MPEG4 and even today's H. 264 These compression algorithms are suitable for low bandwidth transmission. However, the application requirements of high-definition video technology and streaming media have further stimulated the continuous updating of high-speed network technologies and products. The bandwidth of network products has gradually increased from 100M to the current 10G network.

When the PC server was just launched, the application of NVR software was limited due to its high price. The security industry had to use cheaper IPCs to solve video storage problems with hard disk video recorders. Video storage evolved from the first inexpensive tape drive to today's network storage devices. Reviewing the development path of security products and technologies has always been impacted by the development of IT technology, while the demand of the security industry continues to drive IT technology updates.

The penetration of IT methodology in the field of security has been a major stage of development of IT technology since 2000. A large number of hardware and software products have been introduced continuously, and they have also undergone a process from chaos to order. The IT industry has a consistent development direction and common usage. Industry rules have enabled the development of IT technology to withstand the ups and downs of the world economy, and has always occupied the forefront of technological development. The experience summary 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 IT industry standards for various reasons, but with the integration of the two development. IT technology and its methodology promote the development of security is obvious. 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.

The IT methodology's performance in security applications puts aside the specific capabilities of the product or application. How can IT technology and methodology be based on the product's capabilities in the specific layout and implementation of the engineering design?

Take the author's recent discussion with a security product manufacturer R&D staff on the NVR design as an example. Because the manufacturer is worried about the application environment, the network condition is not good enough. Therefore, the number of video inputs that can be managed by the NVR can be managed at a relatively low standard. Users are reluctant to purchase a PC server that installs NVR software, so the NVR is made into a hardware-software device.
