What communication protocol do access control panels use to connect with the system server?

Access control panels typically use the TCP/IP protocol to connect with the system server because TCP/IP (Transmission Control Protocol/Internet Protocol) is the foundational communication protocol used for transmitting data across networks, including local area networks (LAN) and the internet. This protocol suite enables reliable and structured communication between devices, ensuring that data packets are sent and received accurately.

TCP/IP supports various types of data communication and allows access control systems to facilitate real-time data exchange, manage authentication requests, and control the operation of electronic locks and access points. It is particularly well-suited for integration with existing network infrastructures, making it the preferred choice for modern access control systems that often need to communicate with remote servers or cloud-based systems.

Other protocols like HTTP (HyperText Transfer Protocol) are used primarily for web communication, FTP (File Transfer Protocol) is designed for transferring files, and SMTP (Simple Mail Transfer Protocol) is utilized for sending emails. While these protocols have their specific purposes, they do not provide the robust and versatile networking capabilities required for effectively managing an access control system's communication needs.
