For each camera that resides behind a router or gateway, three ports must be forwarded by the router to obtain both audio and video. If audio is not desired, only the HTTP port will need to be forwarded.

The three default ports are:

• 80 (TCP) HTTP Port (allows access to web-configuration and transmits video if other ports are not forwarded)
• 5002 (UDP) Audio Channel Port (transmits synchronized audio)
• 5003 (UDP) Video Channel Port (transmits synchronized video)

These port numbers will need to be changed in the camera configuration on each additional camera that is added behind the router. Port numbers can be changed from the Advanced > Network screen.



Practical Example: Three DCS-3220 cameras are behind a DI-624. The router has a public IP address (WAN) of 63.116.231.25 and an internal (LAN) IP address of 192.168.100.1.

Camera 1 IP address: 192.168.100.207 Ports: 80, 5002 and 5003
Camera 2 IP address: 192.168.100.208 Ports: 81, 6002 and 6003

Each set of three ports must be forwarded to the respective IP address. Set-up for Camera 1 inside a DI-624's configuration is shown below:





This will need to be done for each camera and their respective ports.

To contact these cameras from a remote location (across the Internet), use the Public IP address (WAN) of the router along with the appropriate web port. Using the above example:

To remotely contact camera 1 with Internet Explorer, enter http://63.116.231.25:80
To remotely contact camera 2 with Internet Explorer, enter http://63.116.231.25:81
