What are the advantages of DynamicDNS service?
In order to view camera images over the Internet, you need to know your camera's
global IP address. However, many Internet Service Providers (ISPs) assign their
customers a "dynamic" IP address that changes monthly, weekly, or each time they
log on. Unless you have been assigned a static IP address (an IP address that
does not change periodically) by your ISP, you may find it difficult to access your
camera over the Internet. The Viewnetcam.com service allows you to access your
camera even if your assigned global IP address changes.
