DCS-900 Configuration (continued)
Installing the DCS-900 Behind a Router
Assigning and opening second port in the DCS-900
( For Installing Multiple Cameras)
Opening ports will allow users to view the camera via the Internet. The ports that are opened must be unique for each camera in order to successfully view the images remotely.
3) Open Second Port
The Open Second Port option is used when multiple cameras are being installed on a network OR for using a port other than the default port for image viewing. For each additional camera that is installed, you must select the Open Second Port Option and assign the appropriate Web server and Transfer Image ports for each camera to enable remote viewing.
By default, ports 80 (Web server port) and 8481 (for camera image viewing) are open. If these ports are available for use, you DO NOT have to open a second port and can proceed to the next section. If port 80 is not available (for example, if you are already using port 80 to run a webserver or your ISP blocks access on port 80*) you MUST open a second port and designate a new Web server port (81, 82, 83,…etc) AND a new image transfer port (8482, 8483,…etc). IMPORTANT: Be sure to take note of these settings since these same settings will be used to configure your router.

*IMPORTANT NOTE: Some ISPs block traffic on commonly used ports like port 80 to conserve bandwidth. Be sure to check with your ISP so that you can open the appropriate ports accordingly. If your ISP does not pass traffic on port 80, you will need to change the service port the camera uses from 80 to something else, like 800. If you are behind a residential gateway, you will need to open the corresponding port on your gateway as well. Not all gateways are the same, so refer to your user’s manual for specific instructions on how to forward ports.
