6.3. Internet Access to the Camera on a Local Network
When a leased line or ADSL is used for Internet access, a router is necessary to establish a
local network.
IMPORTANT!
This type of connection requires a static public IP address. Usually ISPs provide a dynamic internal IP
address, which can be used only inside the LAN. Contact your ISP to determine your IP address.
To access the camera over the Internet, use the IP address provided by your ISP (IP
address of the router’s WAN port) and a certain port number.
IMPORTANT!
When accessing over the Internet, you should note that all cameras inside the local network have the
same public IP address. To access the cameras through the same IP address, you must specify a unique
HTTP port number for each camera.
In this case, you should do the following:

Configure the network settings of the IP cameras to match the LAN settings (see
paragraph 5.5 ).

Allow external connections. This can be done by configuring the
“Virtual server”
, which
allows directing any data that reach a predefined WAN port from the Internet so that the
data are
forwarded to the camera’s IP address on the local network. Most modern
routers have the
“Virtual server”
option.
To provide Internet access to your camera(s) through a router, you need to configure the
port mapping using one of the following methods:

Using UPnP in your camera and your router.

Manually configuring a routing table.
6.3.1. Using the UPnP Option
Before using UPnP, make sure your router supports forwarding between LAN and WAN
networks. If so, follow the steps below to set up the Internet access to your camera:

Enable UPnP on your router and configure it.
IMPORTANT!
Some routers do not support UPnP forwarding between LAN and WAN networks. Before configuring,
make sure your router supports this option. If not, your router requires additional configuration.
