What are the mainstream network protocols for access control systems?
For example, in the field access control controller to fully support the direct TCP / IP network connection mode, you can make full use of the existing Ethernet network access control system to achieve the communication connection, making the construction convenience and shorten the duration. Using fast TCP / IP two-way communication mode, making the credit card, alarm and other data within 100ms quickly uploaded to the management of the host, so that data processing and action response is very fast.
The controller supports dynamic port insertion and extraction, and the system can judge the controller's online and offline conditions in real time and react in the host. At present, the technology of access control system is becoming more and more clear in IT direction. Because TCP / IP communication protocol has real-time response and management and convenient scalability, TCP / IP protocol will become the mainstream of IT-compatible protocol.
Network access control refers directly to the TCP / IP protocol for the communication standard network access control system. Compared with the RS-485 communication access control system, TCP / IP network access control system can use an existing (local) network, so that access control system installation becomes more convenient, especially for remote access control users can The existing wide area network is very convenient to achieve the purpose of remote access control. Network access control is mainly used to meet the increased demand for large-scale access control, improve application capacity.
