B.

D.
“Viewnetcam.com” service server
E.
Remote site
Global address is changed.
The contracted provider allocates a global address to the router (or the camera). The global address is not static but dynamic.
“*****.viewnetcam.com” and the current global address is automatically registered.
If you are enrolled in “Viewnetcam.com”, the unique “domain name” (example: *****.viewnetcam.com) will be allocated. The “Viewnetcam.com” service server automatically manages the domain name of camera and the global address of router (or camera) when a camera automatically notifies the service server of the global address.
Current global address is automatically registered via “*****.viewnetcam.com”.
The “Viewnetcam.com” service server registers the global address and the domain name of router (or camera) in the DNS server.
Global address is obtained via the URL (domain name).
By entering the URL (including the domain name) on the web browser when accessing the camera via the Internet, the DNS server identifies the registered global address of router (or camera).
Access using the current global address
The identified global address is used for accessing the router (or camera) to monitor images.
Note
•
Refer to the contracted provider whether the current IP address is static or not.
•
Depending on the provider, local addresses may be allocated. In this case, the DDNS service is unavailable. Refer to the contract provider for further information.
