Default is 80. If you change into another port, you need to add this
port behind IP address when visit the IP device via IE. For example, IP device is
192.168.1.19, web port is 81, and then the login IP address is
http://192.168.1.19:81 . If you want to visit from WAN (Wide Area Network) via
IE, you must map the WEB port on your router equipment.
【
Date Transfer Port
】
Default is 3000.
NOTE: In system backstage, there hide a date control port, default is 3001. Date
control port = date transfer port + 1. If you change the date transfer port into
4000, the system will automatically change date control port is 4001.
When visiting the IP device via WAN, you have to map the date transfer port
and date control port on the router. Because you have to visit the IP device on
WAN through date control port and date transfer port.
