If you use client software to separate control, you need to map multiple ports on the router. For example, real-time picture monitoring of a channel needs to occupy one port, and functions such as remote playback and remote control need to occupy different ports. The specific port number needs to be provided by the software developer.
IE mode only occupies one port, and the default is 80. For example, when we visit 163 or Sina. Com, we just enter the domain name directly. In fact, when we directly enter the domain name to visit a website, IE will automatically call port 80 of the visited server, so port 80 is defined by WINDOWS system, and the default port of monitoring software IE is defined as port 80, which is also because of this. WINDOWS system defines similar ports as 2 1(FTP port), 23 (remote terminal) and 25 (mail sending port).
Let's answer your question:
If there is a router in the network, when the external network wants to access the computer under the router through the WEB service, it must map port 80 to the accessed computer.
If you want to use two monitoring hosts in a network at the same time, all you need to do is change the WEB service port number of one of the hosts, for example, to 8 1 (this setting should be included in the software). If your domain name is www.kloc-0/63. COM, then when you directly enter this domain name, you will use the default port number to access the monitoring host. If you want to visit another one, just enter www. 163. COM:8 1 (port 8 1 also needs mapping).
