DCS-900 Configuration
Advanced > System
Open Second Port:
The Open Second Port option is used when multiple cameras are being installed on a
network OR if you need to use a port other than the default Port 80. If you are installing
only one camera and wish to use the default ports, you do not have to open a second port
on your camera. If you are installing a camera behind a router, you must also open a port
on your router for remote viewing of your camera. For detailed instructions on how to do
this, please refer to the next section of this manual on how to install the DCS-900 with a
router. For each additional camera that is installed, you must select the Open Second
Port option and assign the approriate Web server and Transfer Image Ports for each
camera to enable remote viewing.
For example, for a multiple camera installation, you can open the second port for each
additional DCS-900 from Port 81 to Port 85 as follows:
Internet Camera 1 – IP 192.168.0.101, second Web Port 81
Internet Camera 2 – IP 192.168.0.102, second Web Port 82
Internet Camera 3 – IP 192.168.0.103, second Web Port 83
Internet Camera 4 – IP 192.168.0.104, second Web Port 84
Internet Camera 5 – IP 192.168.0.105, second Web Port 85
IMPORTANT: You MUST also set up your router/gateway for Port Mapping--this will
enable remote viewing of your camera via the Internet. Please refer to your router's
instruction manual on how to open up ports. For additional help on configuring your
camera to work with your router, please refer to the next section on setting up your
camera for use with a router. For installing multiple cameras, ONE port per camera must
be opened on your router, the Web server (HTTP) port.
