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 DynamicDNS service server of the new address in the DynamicDNS. The camera notifies the DynamicDNS service server of the new address in DynamicDNS in the following cases.

–When starting the camera

–When an update interval time has been set

–When clicking the [Save] button

3.The DynamicDNS server contacts the Domain Name System (DNS) server 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 your camera.

Note

•Ask your ISP about what type of IP address you are using.

•Some ISPs assign you a local IP address. In this case, the DynamicDNS service cannot be used.

•If the camera 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
