Troubleshooting
Internet Camera Installation
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, which is DC 5V, for the Internet Camera and verify that the power supply
is well connected. Also, the LED could have been configured to "turn off."
Q: Why does the LAN 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 known 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). Also, the LED could have been configured to "turn off."
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
properly.
Q: Why does the Internet Camera work locally but not externally?
A1: Might be caused from the firewall protection. Check the Internet firewall with your
system administrator. The firewall may need to have some settings changed in order for
the Internet Camera to be accessible outside your local LAN. See page 27 for more
information about installing your camera behind a router.
A2: Make sure that the Internet Camera isn't conflicting with any web server you may
have running on your network.
A3: The default router setting might be a possible reason. Check that the configuration
of the router settings allow the Internet Camera to be accessed outside your local LAN.
Q: Why does a series of broad vertical white lines appear through out the image?
A: It could be that the CMOS sensor (a square panel situated behind the lens that
measures the light signals and changes it into a digital format so your computer can
present it into an image that you are familiar with) has become overloaded when it has
been exposed to bright lights such as direct exposure to sunlight or halogen lights.
Reposition the Internet Camera into a more shaded area immediately as prolonged
exposure to bright lights will damage the CMOS sensor.
