How the DynamicDNS 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 this product over
the Internet.
2.
When your ISP assigned global IP address changes, this product
automatically notifies the DynamicDNS service server of the new address in
the DynamicDNS. This product notifies the DynamicDNS service server of the
new address in DynamicDNS in the following cases.
– When starting this product
– Depending the time to be set at the update interval
– When clicking the [Save] button
3. The DynamicDNS server contacts a Domain Name System (DNS) and
registers your new global IP address to your chosen DynamicDNS address
(such as "bob.viewnetcam.com").
4.
When you enter your DynamicDNS address in your web browser while away
from home or the office, the DNS server looks up the global IP address
assigned to your DynamicDNS address.
5. The DNS server finds your current global IP address and allows you to connect
to this product.
Notes
• Ask your ISP about what type of IP address you are using.
• Some ISPs assign you a local IP address. In this case, you cannot use the
DynamicDNS service.
• If this product is using a port number other than 80, the port number must
be specified at the end of the DynamicDNS URL. For example:
Using port 80: http://(Cameraname).viewnetcam.com
Using any other port: http://(Cameraname).viewnetcam.com:Port
