As ADSL and CABLE MODEM network users usually use dynamic IP address, so once the MODEM
restarts, the IP addresses will change. For this situation, users should apply for DNS services.
To use the Swann DVRs with remote viewing capabilities you may have to “open“ ports on your
Windows® Firewall, your Software Firewall or on the Broadband Router/Modem that you use to
connect to the Internet. Please consult the documentation or help files on the relevant software or
system for instructions on how to do this. To successfully access your cameras from the Internet you
will need to have allowed access to and from the following ports from an outside connection. This
process is also called “Port Forwarding” or creating a “Virtual Server” connection.
For more information on Port Forwarding, please visit www.portforward.com
Once you have correctly forwarded the ports, please check to see what your external IP address is
(this cannot start with 192.168.x.x). You can check this by going to http://www.whatismyip.com (note:
you must do this on the server machine to find the correct external IP of the router.)
You may also have to place the IP address of the Swann DVR in the “DMZ” of your Firewall to enable
the remote viewing interface. Information on how to do this should be detailed in the documentation
covering operation of your Firewall.
As ADSL and CABLE MODEM network users usually use a dynamic IP address, once the MODEM
restarts, the IP addresses can change. Users can opt for a static IP address which does not change by
contacting their ISP. Otherwise users can apply for a DNS service through www.no-ip.com or
www.dyndns.com
