Problem accessing on
the LAN network using
web browser.
The camera is not powered on.
Make sure the camera has been powered on for over 1 minute and its Power indicator (at
the rear end, inside the housing) is lit.
The Ethernet cable is not firmly connected to the camera.
Check if the Ethernet cable is securely connected to the Ethernet port of the camera and
to the network switch.
The entered IP address is incorrect.
Check if the IP address you entered matches the IP address of your camera. If you are
certain that your camera is configured with the same subnet mask as that of your PC,
you can first disconnect other cameras, and then run the iWizard to scan the camera
on your network. You shall then see the your camera's IP address on your network.
(Note if you are running Windows 7/Vista, you need to run iWizard tool with system
administrator rights. Simply right click on the iWizard icon on your desktop, and select
"Run as administrator")
If you're not sure whether your camera is on the same subnet with your PC, reconnect
your camera to your PC directly (configure the IP address of your PC as 192.168.0.X),
and run iWizard again to reconfigure its subnet address to match that of your PC. Then
reconnect it back to the router and run iWizard again.
The PC is not connected to the LAN network.
Please check if your computer has a successful connection to the network. When
successfuly connected, your computer will display the icon below on the task bar.
