In the modern era, access control systems have evolved significantly from traditional radio frequency identification (RFID) methods. As Chinese access control companies enhance their independent research and development capabilities, and with the rapid advancement of emerging technologies, today’s access control systems have made a remarkable leap in terms of convenience, safety, and user-friendliness. The performance and functionality of these systems have continuously improved, leading to an explosive growth in access control products.
One unique feature of China's access control market is the formation of a distinctive linkage application model, which combines various functions such as security, attendance, and building automation. Industry experts suggest that video-based access control may soon become a key barrier in technological and social security. This evolution is driven by both economic growth and supportive government policies, which have contributed to the rapid expansion of the security products market in China.
Looking at the front-end devices, non-contact IC cards remain the dominant choice, accounting for approximately 90% of the market share. In terms of output value, 4-door and 2-door controllers are the most popular. From a sales perspective, single-door and two-door controllers also dominate the market. In the reader market, high-end and mid-to-low-end products maintain a roughly 1:3 ratio.
In terms of system architecture, three main types coexist: RS485, hybrid RS485/IP networks, and full IP architectures. While RS485 remains the most widely used, the IP network architecture is gaining momentum, though it is not yet the mainstream. Many users prefer the hybrid RS485/IP approach for its flexibility and reliability.
From a card-reading technology standpoint, developments are accelerating. CPU cards are gradually replacing traditional IC cards, but they are still not yet the standard. Biometric technologies, such as fingerprint, palm, and facial recognition, are becoming increasingly popular among users. Future systems may require compatibility with multiple reading technologies to meet diverse needs.
Linkage technology has also seen significant progress. Access control systems now need to integrate with CCTV, fire alarm systems, and building automation controls. These linkages can be hardware-based or software-driven, with software-based solutions becoming more prevalent due to the advantages of IP networks. This shift supports digitization and networked operations more effectively.
The future of access control cards is moving toward a unified platform, where one card can serve multiple purposes—such as entry, attendance, and payment. This vision of "one card, one library, one platform" is gaining traction in the market.
Access control systems are now part of the broader Internet of Things (IoT) ecosystem. Previously, these systems operated in isolation, handling tasks like door access, attendance, and parking. Now, they must integrate with other critical systems, including fire alarms, CCTV, and building automation. This integration enhances overall efficiency and security.
For example, fire alarm linkage can be achieved through OPC software, dedicated fire controllers, or power-off release mechanisms. With CCTV, access control devices can either support camera functions or transmit alarm signals for recording. Integration with building automation systems allows temperature and humidity data to be displayed on access control terminals, improving user experience.
Additionally, access control systems can also serve as information platforms, displaying weather updates, welcome messages, or even enabling voting through touchscreens. This multi-functional capability expands the role of access control beyond security into communication and interaction.
Video access control is paving the way for smarter, more connected urban management. It has given rise to a new industry and plays a crucial role in protecting people’s lives and property while promoting social harmony.
Looking ahead, video access control projects will expand from small community setups to large-scale integrated systems across districts and cities. These systems will transition from local area networks to cross-regional digital platforms, supported by cloud computing and IoT technologies. This transformation represents a major step forward in technological development and is becoming a vital component of modern society’s digital infrastructure.
