Access this device

Cannot access the

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.

• Confirm that Default Gateway address is correct.

• The router needs Port Forwarding feature. Refer to your

router's manual for details.

• Packet Filtering of the router may prohibit access from an

external network. Refer to your router's manual for details.

• Access the Network Camera from the Internet with the global

IP address of the router and port number of Network Camera.

• Some routers reject the global IP address to access the

Network Camera on the same LAN. Access with the private IP

address and correct port number of Network Camera.

• When you use DDNS, you need to set Default Gateway and

DNS server address.

• If it’s not working after above procedure, reset Network Camera

to default setting and installed it again.
