1.3 Viewnetcam.com Service
Viewnetcam.com is a free dynamic DNS (DDNS) service provided by Panasonic.
It allows you to choose an easy-to-remember address (such as
"bob.viewnetcam.com") that you can use to view images from your camera over the
Internet.
What is the advantage of Viewnetcam.com 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 because your IP address changes periodically.
Viewnetcam.com service allows you to access your camera even if your assigned
global IP address changes.
See http://www.viewnetcam.com for details.
How the Viewnetcam.com service works
1. Your ISP assigns a global IP address to your Internet access account that
changes periodically. This is the address needed to access the camera over
the Internet.
2.
When your ISP assigned global IP address changes, your camera
automatically notifies the Viewnetcam.com service server of the new address.
3.
The Viewnetcam.com server contacts a Domain Name System (DNS) and
registers your new global IP address to your chosen Viewnetcam.com address
(such as "bob.viewnetcam.com").
4. When you enter your Viewnetcam.com address in your web browser while
away from home or the office, the DNS server looks up the global IP address
assigned to your Viewnetcam.com address.
5. The DNS server finds your current global IP address and allows you to connect
to your camera.
