2008 Chinese door market size is expected to reach 30 million (1)

According to A security & & S the automation of the International English version of 【 2007/2008 in access control market survey 】 statistical results show, 2006, 2007, the access control market with an average annual growth rate reached 28% in 2007, the size of the market in about 24.5 billion (this survey the range of controllers, card reader, card, software), access control products at government agencies, commercial buildings/buildings, Telecom, banking and finance, military, schools, hospitals, businesses, and many other application areas for "multipoint-flowering".

In addition, it is predicted that in 2008 China access control market affected by the international financial crisis, China's economic growth trend gradually ease, and other factors, its growth rate has dropped to around 22% and is expected in 2008, the access control market size of about 30 billion.

Access control system large-scale promotion of TCP/IP communication way

Access control system for networking needs is a real-time response, management and control and the birth of the Internet demands in large systems are often more common: traditional to RS485 bus communication approach to network access control system in data transmission distance there is a natural limit on the theoretical distance only 1200 meters, in practice this distance from access point and the amount will be reduced; and in the large entrance guard system, users increasingly require remote real-time response, management and control, and want to have a network place to view the access control point, therefore, to TCP/IP communication-based network access control system gradually on the surface, there are the rapid development and popularization of the trend.

From the access control market survey of the statistical data can be seen, the current means of communication, TCP/IP mode to occupy the 2007 access communication ratio of 35%, although still slightly lower than the traditional field bus communication (40%), but a traditional RS 485 bus mode and how mixed network TCP/IP access system has a 20% market share for access control, this transition of mixed network is access control system from non-networked systems to networked system's shift.

Network-access control system is catching up.

Shenzhen PHI g Electronics Co., Ltd. technical director Wang, Hyung believes that RS485 bus in theory you can take a bus to 256 controller, but in practice because of the environment, communication distance, General a bus can take 80 desk following controller, which limits the RS485 bus in large systems, and communications based on TCP/IP network access control system in this regard have inherent advantages Ethernet serial access controller of almost not restricted, and the environment from a security point of view, integration trends also require access control system with good scalability, this is the traditional non-network-access control system difficult.

Large projects and networked access control system reigns.

Particularly in multinational projects, the international mainstream way of TCP/IP to use habits impact application network access control system of scale well beyond the traditional access control system. In more than 300 door access control system, TCP/IP networking costs and location convenient for advantages to be obtained more obvious manifestation — — single root network cable cost and RS485 bus mode of twisted pair comparison, reduces the cost of cable, but also enhances the ease of wiring and maintenance, so the price factor is extremely sensitive to the Chinese market in large systems tend to go the way of TCP/IP networking. And network-access control system transfer rate is 10 times the RS485 bus or even dozens of times. In addition, in some individual subnets separated by a distance of access control system, more to RS485 and TCP/IP networked mixed mode: in each subnet to adopt RS485 bus way network, and then through the converter external Ethernet interface implements digital signal output, the final implementation of the network of networks.

But faced with RS485, TCP/IP, RS485 and TCP/IP networking mixed three ways of respective occupy a considerable share of the market, the Beijing door auspicious company Chongqing branch General Manager Zhao Liang ping that three persons will coexist on the market.

But the current hybrid network RS485 and TCP/IP will be in the way of large system development faster, which to some extent accelerates the networked access control system development. However, TCP/IP communication way of development is still affected by the current bandwidth, in areas such as cost, mainly popular in high-end markets, in the low-end market particularly small system, the overall cost is still high. Dashi Xurui Tao believes that network access control system to more than 50% market share still need 3 to 5 years.
