Appendix C: Trouble Shooting
Q: I cannot access the Internet Camera from a web browser.
A1:
 The possible cause might be the IP Address for the Internet Camera is already being used by 
another device.  To correct the possible problem, you need to first disconnect the Internet Camera 
from the network.  Then run the PING utility (follow the instructions in Appendix B - PING Your IP 
Address).
A2:
 Another possible reason is the IP Address is located on a different subnet.  To fix the problem, 
run the PING utility (follow the instructions in Appendix B - PING Your IP Address).  If the utility 
returns “no response” or similar, the finding is probably correct, then you should proceed as follows:
In Windows 95/98/2000 and Windows NT, double check the IP Address of the Internet Camera is 
within the same subnet as your workstation.
Click “Start”, “Setting”, “Control Panel”, and the “Network” icon.
Select TCP/IP from the “Network” dialog box and from the “TCP/IP Properties” dialog box click 
“Specify an IP address”.
If the Internet Camera is situated on a different subnet than your workstation, you will not be able to 
set the IP address from this workstation.  To verify make sure the first 3 sections of the IP address of 
the Internet Camera corresponds to the first 3 sections of the workstation.  Therefore the IP address 
of the Internet Camera must be set from a workstation on the same subnet.
A3:
 Other possible problems might be due to the network cable.  Try replacing your network cable.  
Test the network interface of the product by connecting a local computer to the unit, utilizing a 
standard Crossover (hub to hub) Cable.  If the problem is not solved the Internet Camera might be 
faulty.  
Q: Why does the Power LED not light up constantly?
A:
 The power supply used might be at fault.  Confirm that you are using the provided power supply 
DC 5V for the Internet Camera and verify that the power supply is well connected.
Q: Why does the Link LED not light up properly?
A1:
 There might be a problem with the network cable.  To confirm that the cables are working, 
PING the address of a know device on the network.  If the cabling is OK and your network is 
reachable, you should receive a reply similar to the following (…bytes = 32 time = 2 ms).
A2:
 The network device utilized by the Internet Camera is not functioning properly such as hubs or 
switches.  Confirm the power for the devices are well connected and functioning.
A3:
 The wireless connection might be at fault.  In ad-hoc mode make sure the Internet Camera 
wireless channel and SSID is set to match the PC/Notebook wireless channel and SSID for direct 
communication.  
Under infrastructure mode make sure the SSID on the PC/Notebook and the Internet Camera must 
match with the access point’s SSID.
Q: Why does the Internet Camera work locally but not externally?
A1:
 Might be caused from the firewall protection.  Need to check the Internet firewall with your 
system administrator.
