47D-Link DCS-1100/1130 User Manual
Appendix A - Installing the DCS-1100/1130 on a Router Without UPnP
3) Open the HTTP Port
The HTTP port option under Port Detail Settings is used when multiple cameras
are being installed behind a single public IP address and will be accessed remotely
OR for using a port other than the default port for image viewing. For each
additional camera that is installed, you must assign the appropriate Web server
port for each camera to enable remote viewing.
By default, port 80 (Web server port) is 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
Web server or your ISP blocks access on port 80), you MUST open a second port
and designate a new Web server port (800, 801, 802, etc.). Similarly, if port 554
is not available, you will need to open a dierent port for RTSP.
Note: Be sure to take note of these settings since these same settings will be
used to congure your router.
Note: Some ISPs block trac on commonly used ports like port 80 to disallow consumers from putting a server on their network.
Be sure to check with your ISP so that you can open the appropriate ports accordingly. If your ISP does not pass trac on
port 80, you will need to change the Web server port the camera uses from 80 to something else, like 800. If you are behind
a residential gateway, you will need to open a corresponding port on your gateway as well. Not all gateways are the same.
Please refer to your gateway’s user’s manual for specic instructions on how to forward ports.
