Use the below example code to view the streaming video from your DCS-3420 on your webpage. If the camera is behind a NAT device such as a router, the IP must be edited to reflect the public address of the router. In this example the public IP address of the router is 67.130.140.129 and the port used to access the camera publicly is 3420. You will also need to provide a username and password for the remote connection by adding username:password@ infront of the ip address of the Url Value as shown below.

Please understand that this is not a supported feature of the camera, and beyond providing this code, D-Link can not help design a custom webpage.
