A3: The wireless connection might be at fault. In ad-hoc mode make sure the
Internet Camera wireless channel and ESS-ID is set to match the PC/Notebook
wireless channel and ESS-ID for direct communication. Since The Internet
Camera ad-hoc mode supports two modes (802.11 ad-hoc mode and
proprietary ad-hoc mode), make sure that you are using the same mode on
each device. If they are not the same, the camera will not be accessible.
Under infrastructure mode make sure the ESS-ID on the PC/Notebook and the
Internet Camera must match with the Access Point’s ESS-ID.
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.
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 line appear through out the
image?
A: It could be that the CMOS sensor 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.
Q: The focus on the Internet Camera is bad, how can I correct it?
A1: Adjust the Internet Camera focus manually as described in “Adjusting the
Internet Camera Focus” in the Appendix section of this manual.
A2: If you have previously changed the supplied CS-type lens, you may have
unintentionally installed a C-type lens without fitting the adaptor first.
Q: Noisy images occur. How can I solve the problem?
A1: The video images might be noisy if the Internet Camera is used in a very
low light environment. To solve this issue you need more lighting.
