DDNS (Dynamic DNS)
Many internet connections use a "Dynamic IP address", where the Internet IP address is
allocated whenever the Internet connection is established.
This means that other Internet users don't know the IP address, so can't establish a connection.
DDNS is designed to solve this problem, by allowing users to connect to your LAN using a
domain name, rather than an IP address.
To use DDNS:
1. Register for the DDNS service with a supported DDNS service provider. You can then
apply for, and be allocated, a Domain Name.
2. Enter and save the correct DDNS settings on the DDNS screen of the FCS-3031/3051.
3. Both Router and Camera should use the same port number for DDNS service.
4. Operation is then automatic:
•
The FCS-3031/3051 will automatically contact the DDNS server whenever it detects
that the Internet IP address has changed, and inform the DDNS server of the new IP
address.
•
Internet users can then connect to the camera using the Domain Name allocated by the
DDNS service provider.
Example:
normanyu123456789.dyndns.org is domain host name. 6016 is the port number.
