Can not work with NAT
router
• Maybe NAT router does not support UPnP function.
Please check user’s manual of router and turn on
UPnP function.
• Maybe UPnP function of NAT router is not compatible
to the IP camera. Please contact your dealer to get the
approval routers list.
Some IP cameras are

Access this device
Cannot access the
login page and other
web pages of the
Network Camera from
Internet Explorer
• Maybe the IP Address of the Network Camera is
already being used by another device or computer. To
confirm this possible problem, disconnect the Network
Camera from the network first, and then run the PING
utility to check it out.
• Maybe due to the network cable. Try correcting your
network cable and configuration. Test the network
interface by connecting a local computer to the Network
Camera via a crossover cable.
• Make sure the Internet connection and setting is ok.
• Make sure enter the IP address of Internet Explorer is
correct. If the Network Camera has a dynamic
address, it may have changed since you last checked it.
• Network congestion may prevent the web page
appearing quickly. Wait for a while.
The IP address and Subnet Mask of the PC and
Network Camera must be in the same class of the
private IP address on the LAN.
• Make sure the http port used by the Network Camera,
default=80, is forward to the Network Camera’s private
IP address.
• The port number assigned in your Network Camera
might not be available via Internet. Check your ISP for
available port.
• The proxy server may prevent you from connecting
directly to the Network Camera, set up not to use the
proxy server.
