WIRELESS NETWORK IP CAMERA User’s Guide
I. High Speed Solutions
This information is to help you access high-speed Internet services such as xDSL or a cable modem
connection. However, most high-speed Internet Services provide you with some external IP
addresses, there are several practical issues that should be considered.
AVAILABLE IP ADDRESS
ISP (Internet Service Provider) will provide you with several external static IP addresses ideally –in
which case you can assign any one of these to your Wireless Network IP Camera to make it fully
accessible over the Internet. However, if your service provider supplies you with only one IP
number – which is often the case – this IP number is normally assigned to your PC-leaving no
connection available for your Wireless Network IP Camera.
What can you do if your ISP is unable to provide you with an IP number?
There are a number of other options what you may like to consider: including:
NAT BOX
Short for Network Address Translation, NAT (Network Address Translation) is Internet standard
that allows a local-area network (LAN) to use one set of IP addresses for internal traffic and a
second set of addresses for external traffic. A NAT box located where your LAN meets the Internet
will handle all of the necessary IP address translations and provides:
z Internal IP addresses that are unique to your network – with no possibility of conflict with
IP Addresses used by other companies and organizations.
z The possibility of combining multiple ISDN connections into a single Internet connection.
z An effective firewall for hiding internal IP addresses

NAT Feature in Windows 2000
Utilize the NAT feature in Windows 2000 to allow multiple Ethernet cards in your PC, and you can
then use one of port for the Internet and the other for your internal network. With this solution, you
can let your Wireless Network IP Camera upload image streams to an external Web Server that is
maintained and located with your ISP.
