Symptoms, Causes and Solutions
Listed below are some other frequently asked questions and their answers.
Symptom Possible Cause / Solution
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 LED status
indicator 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. When the camera has successfully established connection, the
LED status indicator appears blue.
The Ethernet cable is damaged.
Try using a different Ethernet cable to determine whether the current cable is faulty.
Sometimes the a faulty Ethernet cable can result in weird connection issues.
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 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 or switch and run iWizard again.
The viewing PC is not connected to the LAN network.
Check if your viewing PC has a successful connection to the LAN network. You can open
a command prompt window (by pressing R and input "cmd" and hit OK) and
then input "ipconfig" and press [Enter]. When your PC is connected to the network, it will
display information on your IP address, subnet mask, etc.
Problem accessing via
wireless connection
(TN30W)
The wireless settings are not configured properly.
Check if the wireless settings are configured correctly. Go to the camera’s Wireless
Settings page and make sure you have inputted the right IP address, SSID and
Keyphrase.
The wireless connection is broken.
If you intend to access your camera by way of wireless connection, please check that:
1. the IP camera is connected to the correct wireless access point.
2. you have correctly set the encryption type and key for the wireless connection. If
you didn’t use a router on your network, the default IP address for the camera will
be 192.168.0.128.
You can check the status of the connection by logging on to your router's maintenance
page or page titled with similar wording. Consult with the manufacturer of your router
for detailed instruction.
