Section 3 - Configuration
Note: Some ISPs block traffic on commonly used ports like port 80 to prevent 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 traffic 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 router, you will need to open a
corresponding port on your router as well. Not all routers are the same, please refer to your router’s user’s manual for specific instructions
on how to forward ports.
(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.
1) Open the HTTP Port
The HTTP Port option 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). IMPORTANT: Be sure to take note of these settings since these same settings will be used
to configure your router.
