Access control products expand growth system linkage unique Chinese characteristics

Expanded growth of access control products with unique Chinese characteristics It is not difficult to see that the traditional access control system controls the entrance and exit passages through radio frequency identification technology, and with the improvement of the independent research and development capabilities of our access control companies and the flourishing development of emerging technologies, today’s access control systems It has made a qualitative leap in terms of convenience, safety, and humanity, and has continuously improved its technical performance. The access control products have seen an exploding growth, and the access control card has formed a unique linkage application with Chinese characteristics. Industry knowledge indicates that video access control may become a barrier of technological and social security.

The growth of access control products has seen an exploding growth. In recent years, driven by the rapid development of the economic environment and the favorable policies of the country, the scale of China's security products market has continued to expand and grow rapidly. Among them, the access control products have shown an expansive development. .

From the perspective of front-end identification devices, non-contact IC cards are the absolute mainstream, accounting for about 90% of the market; from the perspective of output value, 4-door and 2-door controllers dominate the market; from the sales point of view, single door And two-door controllers exceed other types of controllers; the reader market, high-end products, and mid- to low-end products are approximately 1:3.

From the system architecture point of view: there are RS485 architecture or RS485IP network hybrid architecture or all-IP network architecture, three coexist, but the RS485 architecture is the most popular, in recent years, all-IP network architecture has developed rapidly, but the IP network architecture is still not the mainstream of the market. Users prefer the hybrid architecture of the RS485 IP network.

From the point of view of card reading technology, development is fast. In recent years, CPU cards will gradually replace IC cards, but it will take time to become mainstream. Biometric technology will be favored by users, especially fingerprints, palms, and facial recognition. In the composed system may also require a variety of reading technology compatibility.

From the linkage technology point of view: put forward high requirements for the linkage, especially with television monitoring, fire alarm, building automation control system linkage. The linkage method is based on the linkage of basic hardware to the development of linkage based on pure software. Especially with the rapid development of IP networks, it highlights that the network provides convenience for software-based linkage, and only software linkage is more suitable for digitization and networking.

From the point of view of the card application: Because of the proximity card-based or biometric-based identification, the access control will inevitably develop toward the single card, and the prospect is "one card, one library, one platform." This trend has gradually been accepted by the market.

Access Control Card: The unique linkage application with Chinese characteristics The access control card system is a very small part of the Internet of Things. The Internet of Things encompasses a wide range, which poses a great challenge to the access control card system. Previously, the card system for access control was an independent system. It was relatively closed, and applications such as door opening, attendance, consumption, patrol, elevator control, and parking lot were performed around the card; now, with the development of automation, the system needs to cooperate with fire alarms and CCTV. Linkage, effective integration with the BA system (building automation system), effective integration with the information release system and so on.

1. There are generally three ways to achieve linkage with fire alarms. First, the soft linkage of fire is achieved through OPC; secondly, fire linkage information is received by the fire linkage controller in the access control one-card product; and thirdly, the fire linkage is forcibly executed through the power-off of the release device.

2. There are generally two types of expressions associated with CCTV. First, the access control card device or the system itself supports the camera function, which can be used to record and capture the scene. Second, the access control card device or system transmits the alarm signal to the CCTV system, allowing it to record and capture.

3. Effective integration with BA system (building automation system), the interactive display BA system will generally monitor the temperature and humidity, and access control card devices are generally installed near the door, the user is easy to see and see, then the BA The temperature and humidity are transmitted to the LCD screen of the device, so that the user can easily understand the current situation. The integration with the BA system is often accomplished through the building automation protocol, and the Sedona protocol standard is more popular and convenient on the market.

4. The access control card system has the function of releasing information. In many cases, information is released as an independent system. For example, Focus Media, which you have seen, hangs the TV on both sides of the elevator or in the building lobby and plays advertisement information. The access control card system can also perform some functions of information release, such as displaying weather information and welcome messages on the LCD screen of the card reader. Currently, some devices on the market use touch screens. When some companies need employees to participate in the voting, we can use the functions of the one-card device to allow participants to swipe their cards on the device and then select the information to be voted on the touch screen to implement the functional extension of the card system.

Video Access Control Becomes a Technological Social Security Barrier The 21st century is the information age. The information industry will also become the leading industry in the 21st century. The growth and development of the information industry will inevitably require a strong grassroots technical support. That is the Internet of Things and cloud technologies. . Under the influence of the global informatization drive, China has formed a complete industrial system of the Internet of things and cloud computing, and certain areas have formed a certain market size.

In the area of ​​IoT application infrastructure service industry, although not all cloud computing industries can be included in the IoT industry, cloud computing is an important part of the IoT application infrastructure service industry, and large-scale applications of IoT will also be greatly affected. Promoting the development of cloud computing services, domestic cloud computing business services are also starting. At present, there is a gap between China's infrastructure for cloud computing services (IDC center), cloud computing software and hardware industry support, and the core technology of ultra-large-scale cloud computing services. In terms of cloud security, Chinese enterprises have certain characteristics and advantages. With the advancement of the scale of Internet of Things applications, the rapid development of the Internet and the deepening of the country's informatization process, China's cloud computing services will form a huge market demand space.

The application of video access control has created a brand-new road for intelligent, digital, and convenience of urban management in China. It has led to the birth of a new industry, and it will play an important role in safeguarding the safety of people's lives and property and promoting social harmony. The role.

In the future, the video access control project will be applied from small-scale small platform projects in communities and villages to pilot large-scale integrated management systems in districts and cities. The construction of the platform will also transform LAN communication in a small area into a cross-network segment. a large-scale digital integrated management platform across regions, and such a large-scale platform is precisely the need of leading technological forces such as cloud computing and the Internet of Things as a support. It has become a bright banner in the future rapid development of scientific and technological forces, and it has become an entire society. An integral part of the modernization process.
