Frequently Asked Questions
Internet Camera Installation
11 Why does the Power LED not light up constantly?
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. Also verify that the power supply is well
connected, and/or the option to turn off the LED is enabled.
12 Why does the LAN LED not light up properly?
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).
Another possible problem may be that 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, and/or the option to turn off the LED is enabled.
13 Why does the Internet Camera work locally but
not remotely?
This might be caused by 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. Refer to page 39 for more
information about installing your camera behind a router.
Make sure that the Internet Camera isn’t conflicting with any web server you may have
running on your network.
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.
14 Why does a series of broad vertical white lines
appear through out the image?
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.
