2.5 TROUBLESHOOTING NETWORK CONNECTIONS

OPENING PORTS

The most common factor causing network connection issues is for communication between
the device and a device outside the network to be blocked. The router's built-in-firewall is
designed to keep malicious users and software out of the network. At times, this can also
block legitimate connections. To avoid this, routers can allow communication to pass through
specific ports within the firewall. These "virtual tunnels" only allow access to specific devices
within the network. Properly managed with passwords and other safeguards, these do not
pose a threat to the security of the network.
If your network's router has the UPnP feature turned on, it and the camera should "discover"
each other on the network in less than a minute. Ports 85 and 37777 will be "forwarded"
to the camera's local network IP address, allowing it to communicate with the Internet. The
former allows you to control the camera, while the latter port is used by the camera for the
video stream.
However, some brands of routers, such as the 2Wire used by AT&T for it's Uverse service
do not include this feature. In this case, the ports will need to be manually forwarded using
one of the methods described on the next few pages. You will only need to use one of these
methods - which are the same if you are using a Macintosh or Windows PC. If you are still
unable to connect your NVR to the Internet using any of these procedures, the likely cause
is the presence of multiple routers on your network. Solutions to overcome that situation are
presented at the end of this section.
Regardless of the method you use, you will need to get your router's Public (Internet) IP and
Gateway addresses in order to log into the router, and eventually connect to the camera.
Option 1: UPnP
Check your router's manual to confirm the presence of the UPnP feature. You may need to log
into your router to turn it on. There are legitimate reasons to disable UPnP, but you may wish
to enable it briefly in order to allow the camera to connect. Once you've confirmed that the
camera's ports have been opened and you've set the camera to use a Static IP address as
described later in this section, you can disable UPnP.
The location of the UPnP settings within your router vary by brand and model. Consult your
router's manual to locate and enable this feature before continuing.

Option 2: Opening Ports Using DMZ
The exact location of DMZ within the router's settings vary by manufacturer so please consult
your router's manual for the location of this feature. The method for accessing your router's
settings, however, is pretty standard.
NOTE! If you are an AT&T Internet or Uverse customer, you should follow the
instructions laid out in Option 3 as they specifically apply to the brand of router
used by AT&T.
STEP 1. On a computer connected to
the same router as your camera,
open a web browser and enter the
Gateway (Router's IP address) into
the browser window's address bar to
access your router.
STEP 2. Locate the DMZ settings in
your router. Each manufacturer is
different so please consult your
router's manual for the location of this
setting. Two examples are shown at
right.
STEP 3. Enable DMZ.
STEP 4. Enter the NVR's IP address.
STEP 5. Click on Apply or Save to
preserve your settings.
Leave your router control panel open as you
will need to obtain DNS information from
your router in Section 1.5 Domain Name
System (DNS). You should now proceed to
the section entitled Confirming that Ports
are Opened.
