TCP/IP network door access control system is based on TCP/IP communication protocol, which uses network optical cable to transfer data of door control information. It has a built-in internet communication port on its main board and could be connected with router or hub directly throught network cable.
By TCP/IP network, the door access control system could manage doors in a same LAN, or a large WAN, or on internet. In reality, each access control main board could be assigned an IP address so the software could visit and manage it individually, for example, it could be assigned 192.168.1.1 (LAN) or 192.16.0.1(WAN, different from the previous IP network). For internet control, Global Keyaccess adopt DDNS(Dynamic Domain Name Service) technology for convenient and efficient online control, by DDNS combined technology, the operator could control the system worldwidely with ease and it is much better than old day’s telephone line control method.
The main difference between TCP/IP and RS485 access control system has two factors, first is the transmission speed, TCP/IP is much faster than RS485(TCP/IP is 10M/100M Bytes while RS485 is 9600Baud, 1Baud=1 bit per second), second is the capacity of the whole system, the size for RS485 and LAN is 255, the size for WAN or Internet use is unlimited.
Note: Dynamic DNS is a system which allows the domain name data held in a name server to be updated in real time. The most common use for this is in allowing an Internet domain name to be assigned to a computer with a varying (dynamic) IP address. This makes it possible for other sites on the Internet to establish connections to the machine without needing to track the IP address themselves. A common use is for running server software on a computer that has a dynamic IP address, as is the case with many consumer Internet service providers.
