SETUP > Dynamic DNS
If you have a DSL or Cable service provider that changes your modem IP address periodically,
Dynamic DNS (Domain Name Service), a method of keeping a domain name linked to a
dynamic IP address, is useful. With most Cable and DSL connections, you are assigned a
dynamic IP address and that address is used only for the duration of that specific connection.
With the DCS-2121, you can set up your DDNS service and the DCS-2121 will automatically
update your DDNS server every time it receives a different IP address. Depending on the
service, this update may take a few hours.
Enable DDNS: Check this checkbox to enable the DDNS function of the camera.
Server Address: Use the dropdown box to the right to select a DDNS service to use.
Host Name: Type in the Host Name of the DDNS service you wish to use.
User Name: Enter your User Name for the DDNS service you wish to use.
Password: Enter the password for the DDNS service you wish to use.
Verify Password: Retype the password for the DDNS service you wish to use.
Timeout: This sets the number of hours between DDNS updates.
After making any changes, click the Save Settings button to save your changes, or click the
