Operating Environment
This product includes all of the following items. If any item should be missing, please contact your local
dealer.
VN-C2WU main unit
Ferrite core
Instruction manual (this document)
The environment described below is necessary for operation of the VN-C2WU.
A personal computer running the following WWW browser software:
WWW browser software that is compatible with JavaScript or Frame. Netscape 4.0 or higher,
or Internet Explorer 4.0 or higher, is required.
CPU performance and memory capacity should be the recommended values for the WWW
browser software used. To ensure the smooth display of animated images on a large screen,
these values should be even larger than those recommended.
Also, images from the camera will not be correctly displayed in the 256-color mode, etc.
• In the case of Internet Explorer, an environment in which JAVA can be executed correctly is
necessary.
LAN environment
The VN-C2WU operates as a web browser using HTTP protocol.
Access linking by host name is possible with an environment able to use DNS (Domain Name
System).
The VN-C2WU and a personal computer can be connected directly at 1: 1 by using cross
cables. (Although rare, the use of cross cables is not possible with some LAN boards.)
Caution
The standard used for connection to the VN-C2WU is 10BASE-T.

To ensure correct usage
When installing, avoid the following.
• Locations subject to rain and water.
• Locations where the ambient temperature exceeds the range of 0 to +40 °C.
• Locations with vibration.
• Locations with excessive dust, oil or gas.
When this product is used with AGC on (camera setting: Auto), sensitivity will be increased
automatically in dark places and the screen may flicker in some cases. This is not a
malfunction.
When the color balance of this product is used with the camera setting at Auto, in some
cases the recorded colors may differ slightly from the natural colors due to the principle of
the automatic tracking color balance circuit.
When any bright object such as a lamp, etc., is photographed, white bands may appear
above and below the bright object. This is called smearing, a phenomenon caused by the
characteristics of the individual pixels, and is not a malfunction.

VN-C2WU Installation and Setup
Before starting installation and setup
It is necessary to set an IP address for each VN-C2WU unit. Use the following procedure for the setup of
individual units. (If the power is not turned on, the installation operation can be performed at one time.)
1. Install the VN-C2WU.
Only in cases of installation in a location where the power cannot easily be turned on, complete
steps 2 to 4 before installing.
2. Connect the VN-C2WU to a network.
(With the VN-C2WU power turned on.)
3. Set the VN-C2WU IP address.
When setting the VN-C2WU IP address, be sure to contact the network manager for assignment
or approval.
4. VN-C2WU access test.

Caution
2. Connecting to a network
(Ethernet, Fast Ethernet through Auto negotiation HUB).
Turn on the power of only one VN-C2WU unit.
When network connection is completed and the power is turned on, the VN-C2WU unit will be
connected to the network at the following IP address.
Factory set (Default) IP address : 192.168. 0. 2
All VN-C2WU units are set to the same IP address at the factory; therefore, if
the power of multiple VN-C2WU units is turned on at the same time, correct
access will not be possible. Always turn the power on for only one unit at a
time. If duplication occured, perform the proper processing, wait for 10 min. or
more or turn off the power of all units on the network and then turn the power
on again; otherwise, correct access will not be possible.

[Resolution]
Three different image sizes are available: 640 x 480, 320 x 240 and 160 x 120.
[Compression Rate]
The compression ratio has an inversely proportional relationship to image quality but increasing the
compression ratio increases the number of frames that can be displayed per second.
[Frame Rate]
Frame rate sets the upper limit for the number of image frames sent from the VN-C2WU per second.
(fps is the abbreviation for frames per second)
Caution
If the frame rate is not set to 1fps or less in the band below 10Mbps, the
pan/tilt operations may not be possible from the control page in some cases.
(ISDN 64k, 128k, analog 56k, etc., are pertinent.)
Caution
Caution
The number of frames actually sent and displayed per second depends on
the performance of the personal computer and WWW browser software, and
on the LAN environment, etc. When communication interference from
processing being performed by other users is anticipated (especially in
environments where the load on the network is relatively heavy), it is
advisable to set a low value for the frame rate.

The colors are unsatisfactory.
• Check the color adjustment of the
displaymonitor and video card.
Colors will differ slightly depending on the
video card and display monitor used with
the personal computer. Improvement is
sometimes possible by adjusting the color
setting of the display monitor. Depending
on the video card used, the color can
sometimes be adjusted with Screen
Properties (click the right mouse button
from the Desktop).
• Switching to True Color (24-bit) display
Natural color reproduction is difficult at a
setting of High Color (16-bit) or less. The
use of True Color is recommended.
• Adjusting the color balance
Color balance can be changed using
VN-C2WU Setting Page → Image Quality
Menu → Color Balance.
(Cont'd on the next page)

The colors are unsatisfactory. • Try changing Camera Auto/Manual Setting
on the VN-C2WU Setting Page from Auto
to Manual and then back to Auto.
When using a different light sources for re-
cording
(For example, when moving back and forth
between outdoors under sunlight and indoors under fluorescent lighting.)
In some cases, time is required for the
auto tracking white balance to start operating.
In this case, the white balance can be star-
ted rapidly by temporarily changing the
setting from Auto to Manual and then
checking.
