Useful Utilities
GV-VMS support the advanced utilities, such as Authentication Server, Fast Backup and
Restore program, Bandwidth Control Application and GV-IP Device Utility to enhance the
system performance in a security network.
9.1 Dynamic DNS
GV-Dynamic DNS allows you to register domain names that always point to your GV-VMS
server. This application is only necessary when your server is using a dynamic IP address.
The GV-Dynamic DNS will update the server’s IP address to DNS Server every 10 minutes.
Therefore, even if your server’s IP address changes, you can still locate it by using the
registered domain name.
Note: GV-Dynamic DNS uploads IP addresses over the Internet through ports 80 and 81. If
your GV-VMS server is connected behind a router or firewall, make sure ports 80 and 81 are
enabled. GV-Dynamic DNS will only upload global IP addresses. If your GV-VMS server is
using virtual IP, NAT port mapping should be done first.
IMPORTANT: 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. Besides GeoVision, you can also obtain the free
DDNS service from these providers: DynDNS.org
and No-IP.com.
