B PING Your IP Address
The PING (Packet Internet Groper) command can determine
whether a specific IP address is accessible by sending a packet to
the specific address and waiting for a reply.
It can also provide a
very useful tool to confirm if the IP address conflicts with the
Internet Camera
over the network.
Follow the step-by-step procedure below to utilize the PING
command but first you must disconnect the
Internet Camera
from the network.
Start a DOS window.
Type ping x.x.x.x, where x.x.x.x is the IP address of the
Internet
Camera
.
The succeeding replies as illustrated below will provide useful
explanation to the cause of the problem with the
Internet
Camera
IP address.

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 on “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 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 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.
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.
A2:
The default router setting might be a possible reason.
Need
to double check if the configuration of the default router settings
is required.

Q:
Why does a series of broad vertical white line appears
through out the image?
A:
A likely issue is that the CMOS sensor becomes overloaded
when the light source is too bright such as direct exposure to
sunlight or halogen light.
You need to reposition the
Internet
Camera
into a more shaded area immediately as this will damage
the CMOS sensor.
Q:
There is bad focus on the
Internet Camera
, what should be
done?
A1:
The focus might not be correctly adjusted for the line of
sight.
You need to adjust the
Internet Camera
focus manually as
described in Adjust
Internet Camera
Focus.
A2:
There is no adaptor fitted with your C-type lens.
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 is a very low light environment.
To solve this issue you
need more lighting.
Q:
There is poor image quality, how can I improve the image?
A1:
A probable cause might be the incorrect display properties
configuration for your desktop.
You need to open the Display
Properties on your desktop and configure your display to show at
least 65’000 colors for example at least 16-bit.

Note:
Applying only 16 or 256 colors on your computer will produce
dithering artifacts in the image.
A2:
The configuration on the
Internet Camera
image display is
incorrect.
Through the Web Configuration Image section you
need to adjust the image related parameter for improve images
such as brightness, contrast, hue and light frequency.
Please refer
to the Web Configuration section for detail information.
Q:
There are no images available through the web browser?
A:
The ActiveX might be disabled.
If you are viewing the
images from Internet Explorer make sure ActiveX has been
enabled in the Internet Options menu.
Alternatively, you can use
the Java Applet for viewing the required images.
