In today’s security system development in China, the infrastructure of these systems has not received sufficient attention. This is mainly due to the neglect of using IT technology and its methodologies to build a solid foundation for security systems. For instance, IP video streams are transmitted over networks or sent directly to control centers to meet real-time monitoring needs. These security data carriers—networks, servers, storage devices—are all part of IT infrastructure. Therefore, applying IT technology and its methodologies to design the security system's infrastructure is essential.
The integration of IT and security technologies is a growing trend. The evolution of digital video surveillance has always been influenced by IT advancements, especially network technologies. Early video compression standards like MJPEG were limited by network capabilities, followed by MPEG2, MPEG4, and now H.264, which supports low-bandwidth transmission. Meanwhile, the demand for high-definition video and streaming media has pushed the development of faster network technologies. Network bandwidth has increased from 100M to 10G, reflecting this ongoing progress.
When PC servers first emerged, the high cost of NVR software limited its adoption. As a result, the security industry relied on more affordable IP cameras and hard disk recorders for video storage. Over time, storage solutions evolved from tape drives to modern network-attached storage (NAS) and storage area networks (SAN). This shows that the development of security products has always been shaped by IT advancements, while the security industry’s demands have also driven IT innovation.
Since 2000, the application of IT methodologies in the security field has led to significant growth. A wide range of hardware and software solutions have emerged, moving from disorganized practices to standardized and structured approaches. The IT industry follows consistent development paths and common standards, allowing it to remain at the forefront of technological progress despite economic fluctuations. The key to success lies in delivering universal, reliable, and compatible products and systems, along with unified operation and maintenance procedures.
Although the security industry still lags behind IT standards, the integration of both fields is accelerating. IT technology and methodology are clearly driving the advancement of security solutions. Even if manufacturers haven’t reached consensus at the application level, they should at least agree on product architecture, engineering design, and maintenance models to elevate the entire industry to a higher standard.
How can IT technology and methodology be effectively applied in the layout and implementation of security systems? Take, for example, a recent discussion with R&D engineers from a security product manufacturer about NVR design. Due to concerns about unstable network environments, the NVR was designed to handle only a limited number of video inputs. Also, users were hesitant to buy PC servers for NVR software, so the device was made into a dedicated hardware-software solution. If IT methodologies were applied, how would the R&D strategy change?
By adopting IT best practices, security systems can become more scalable, efficient, and user-friendly. The future of security depends on embracing IT as a core component, ensuring that systems are not just functional, but also intelligent and adaptable.
