7.2.2 Connection over Internet
DDNS (Dynamic Domain Name System) provides another way of accessing GV-AS / GV-EV
Controller when using a dynamic IP. DDNS assigns a domain name to the controller, so the
GV-ASManager can always access the controller by using the domain name.
To enable the DDNS function, you should first apply for a domain name from the website of
the DDNS service provider. There are 2 providers listed in the controller: GeoVision DDNS
(V2) and DynDNS.org. To register at the GeoVision DDNS Server, see the following
instructions. For details on DynDNS, please consult them at
www.dyndns.org .
