To enable the DDNS function, you first should register a domain name from one of the two
supported DDNS service provider’s websites.
Figure 2-3
2.3.1 Registering a DDNS Domain Name
To obtain a domain name from the GeoVision DDNS Server:
1. Click the
GeoVision DDNS
button on the
Network Configuration
page (
Figure 2-2
). Or
open an Internet browser, and type the Web address
http://ns.gvdip.com/register.aspx
.
The GV-Dynamic DNS Service V2 page appears.
Note:
1. Dynamic DNS uploads IP addresses over the Internet through ports 80 and 81. If your
controller is connected behind a router or firewall, make sure ports 80 and 81 are
enabled. Dynamic DNS will only upload global IP addresses. If your controller is using
virtual IP, NAT port mapping should be done first.
2. The DDNS service is provided purely as a favor to you. We hope it simplifies the process
of trying to connect an IP video device to the network. GeoVision does not and cannot
warrant that the DDNS service will be uninterrupted or error free. Please read Terms of
Service carefully before using the service.
