Question

Answer or Resolution

UPnP NAT Traversal

Doesn

‟t 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
working but others are failed

Maybe too many IP cameras have been installed on the LAN, and then NAT router
is out of resource to support more cameras. You could turn off and on NAT router to
clear out of date information inside router.

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.

 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.

 If the problem is not solved, the Network Camera might be faulty. Contact your

dealer for further help.

Image or video does not
appear in the main page

 The first time the PC connects to Network Camera, a pop-up Security Warning

window will appear to download ActiveX Controls. When using Windows XP, or
Vista, log on with an appropriate account that is authorized to install
applications.

 Network congestion may prevent the Image screen from appearing quickly. You

may choose lower resolution to reduce the required bandwidth.

Check the device‟s ActiveX is
installed on your computer

Go to C:\Windows\Downloaded Program Files and check to see if there is an entry
for the file “IPCamera Control”. The status column should show “Installed”. If the
file is not listed, make sure your Security Settings in Internet Explorer are configured
properly and then try reloading the device‟s home page. Most likely, the ActiveX
control did not download and install correctly. Check your Internet Explorer security
settings and then close and restart Internet Explorer. Try to browse and log in again.
