The evolution of technology has significantly impacted the architecture of access control systems. By tracing its development, we can predict what lies ahead in the near future. <\/i><\/p>\n

The Past<\/h4>\n

\nLong ago, computer networks were still a rarity. At that time, access control systems were built as follows: a master-controller serviced a limited number of controllers, while a computer served as a terminal for programming and displaying information. The logic of operation was defined by the master-controller, which managed the secondary controllers. <\/p>\n

Secondary controllers could not exchange information directly with each other; the exchange occurred through the master-controller. This model imposed significant limitations on the development of access control systems.<\/p>\n

\"New
\n<\/a><\/noindex>
\nThe advancement of computer technology and network equipment influenced the architecture of systems, resulting in the emergence of multi-server access control systems. Changes affected the software but bypassed the controllers, which limited the scaling and development of the system. <\/p>\n

\"New
\n<\/p>\n

This agreement<\/h4>\n

\nThe development of microelectronics allowed equipment manufacturers to fundamentally change the architecture of access control systems. The previous model was replaced by an architecture where controllers could exchange data directly with each other. <\/p>\n

In this model, software could be installed anywhere within the local network, and integration with other security systems was simplified through the use of a unified information exchange environment.<\/p>\n

\"New
\n
\nThis model continues to operate successfully today, but the current level of technological development enables the construction of systems with a completely different architecture. There is a wide range of physical and logical options for ensuring communication between system components and means of interaction between users and the system. Among these are console applications, specialized controllers with graphical interfaces, various control panels, tablet computers, and smartphones, as well as the use of standard WEB browsers. The capabilities of microcontrollers already far exceed the resources of computers used in the early access control systems. <\/p>\n

Further Development of Access Control System Architecture<\/h4>\n

\nController as a Server<\/i><\/b><\/p>\n

A server is necessary in an access control system to correctly execute the system's business logic and store data about users and events. Twenty years ago, this was managed by a master controller. Since then, the requirements for access control systems have significantly increased, and modern controllers far exceed the capabilities of 20-year-old computers. <\/p>\n

The system server can also be installed directly in the controller if it has the necessary resources. A server deployed in the memory of controllers has significant advantages. The first of these is the ease of system launch. <\/p>\n

\"New
\n
\nOne of the controllers in the system is designated as the server (or master, as it was once called), and it receives instructions on which controllers it will work with. That's it, the system is ready. To work with remote objects, the controller designated as the server is assigned a 'white' IP, which is provided to other controllers, allowing them to connect to it independently. For integration with 1C, you simply need to provide the controller's address in the program. For integration with a license plate recognition system, you need to specify the vehicle's number and the IP address of the camera or system capable of recognizing license plates.<\/p>\n

Access Control System as a Service<\/b><\/i><\/p>\n

The second important advantage is user convenience. The client no longer needs to worry about which computer to deploy the system on, where it will be located, and who will maintain it. Now the client simply receives an IP address, a login, and a password\u2014allowing them to monitor employee discipline, set access rights, and issue guest passes using any browser they prefer. All that's required is to purchase a turnstile and a controller (or a ready-made solution like an electronic checkpoint) and identifiers. The system is ready.<\/p>\n

This approach aligns perfectly with the modern trend of perceiving access control systems as a service. The client does not consider the installation and maintenance of the system; all of this is handled remotely by specialists. An inevitable question arises regarding the controller's responsiveness and its ability to work with 10,000 users and 200 turnstiles. While this is not currently feasible, the database can be located in the cloud or on a dedicated server. server<\/a>Over time, the capabilities of controllers will expand, and the system described above can be deployed even in large enterprises with many employees and execution devices. <\/p>\n

The Future<\/h4>\n

\nStandardization as a Trend<\/b><\/i><\/p>\n

The architecture of access control systems will be based on \"smart\" controllers that will interact with each other autonomously, having several master controllers performing the role of a server. They will also be able to merge on a single server (or several) servers<\/a>), providing the necessary logic for interaction.<\/p>\n

\"New
\n
\nIt is essential for protocol standardization to be supported by all market players \u2013 not only at the controller interaction level but also at the systems interaction level. <\/p>\n

It is possible that the development of a single standard will be implemented in the distant future. However, even if that does not happen, standardization of interaction based on REST API and access to information through a browser should be implemented as soon as possible.
