Operating Environment
The environment described below is necessary for operation of the VN-C3WU.
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-C3WU 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).
Caution
The standard used for connection to the VN-C3WU is 10BASE-T.
The VN-C3WU 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.)
9
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 - 40
(recommended) degrees C.
• Locations with vibration.
• Locations with excessive dust, oil or gas.
● When this product is used with AGC on (Auto on), the sensitivity will be
increased automatically in dark places, so the screen may flicker in some
cases. This is not a malfunction.
● When this product is used with Auto on, 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.
● When panning and tilting the VN-C3WU, do not apply force to any part
other than the body because this could result in damage or a malfunction.
● Use caution to avoid catching on the sensor insert button of the alarm
input/output jack. In case this happens and disconnection from the alarm
input/output jack occurs, return to the original location and use there.

VN-C3WU Installation and Setup
Before starting installation and setup
It is necessary to set an IP address for each VN-C3WU 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-C3WU.
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-C3WU to a network.
(With the VN-C3WU power turned on.)
3. Set the VN-C3WU IP address.
When setting the VN-C3WU IP address, be sure to contact the network manager for
assignment or approval.
4. Alarm IN/OUT connection.
5. VN-C3WU access test.
This test is performed after any change to confirm the IP address.

Installation and setup
1. Installation
Use the optional bracket (Model VN-BK30) for installation.
Make the power and network connections after completion of the installation work.
Caution
Install in a location with sufficient strength to prevent falling.
VN-C3WU units can be installed as shown in the diagram below.
1 Attach the ceiling fixer with the P hole
pointing toward the front of the camera.
3 Attach the drop-prevention wire of the
ceiling fixer to the camera body fixer.

4 Mount the VN-C3WU on the ceiling fixer
by rotating clockwise, then tighten the
screw of the camera body fixer.

2. Connecting to a network
Turn on the power of only one VN-C3WU unit.
When network connection is completed and the power is turned on, the
VN-C3WU unit will be connected to the network at the following IP address.
Factory set (Default) IP address 192. 168. 0. 2
❉ Use a straight cable when
connecting to a hub.
Use a cross cable when
connecting directly to a PC.
Power supply connection cable
● About the power supply connection cable
• Length: 30m or less.
• Recommended model: UL1007, UL1015 or equivalent cable with wire
equivalent to ID AWG #20 or larger.
Caution
All VN-C3WU units are set to the same IP address at the factory; therefore,
if the power of multiple VN-C3WU units is turned on at the same time,
address duplication will occur and correct access will not be possible. Always
turn the power on for only one unit at a time. If address duplication occurred,
perform the proper processing and 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 may not be possible.
Caution
VN-C3WU unit is intended to be Supplied by a Listed Direct Plug-In Power
Unit marked “Class 2” and rated from 11 to 15 V dc, 2 to 2.5 A.

● Cable connection and disconnection
Press the sensor insert button when connecting and disconnecting cables.
After connecting or disconnecting, make sure the sensor insert button
returns to its original position.
● About the alarm IN/OUT connection cables
• Length: use cables with a length of 50m or less.
• Recommended model: UL1007, UL1015 or equivalent cable with wire
equivalent to AWG #22 - AWG #18.
Caution
External noise may affect the alarm working properly even with a cable
length of 50m or less. In such cases, it is necessary to either change to the
use of shielded cable to prevent influence by noise or to change the wiring
route to avoid passing close to the source of the noise.

(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
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.

Troubleshooting
The IP address to which
the VN-C3WU was
changed has been
forgotten.
The password protection
was set but the password
was forgotten.
Color balance is
unsatisfactory.
Unknown IP addresses are handled as
repairs. Please consult your local dealer.
Disabling of the password protection function
is handled as a repair. Please consult your
local dealer. Be prepared to show proper
identification for safety purposes.
• Check the display and video card color
adjustments.
Color balance will vary slightly, depending
on the personal computer, video card and
monitor display used. Improvement is
sometimes possible by adjusting the color
settings of the monitor display. Also,
depending on the video card used, the
colors can sometimes be adjusted by right
clicking the mouse on the desktop to access
"Screen Properties."
• Color balance is sometimes unnatural when
a True Color (24-bit) display is switched to
High Color (16-bit). The use of True Color
is recommended.
• Adjust Color Balance.
Color balance can be adjusted by using the
Color Balance item in the Image Menu in
the VN-C3WU Settings page.

setting in the VN-C3WU Settings Page from
Auto to Manual, and then back to Auto
again.
When changing between scenes with
different light sources (for example, when
moving from outdoors with sunlight to
indoors with fluorescent lighting), there may
be a slight delay before the automatic
tracking white balance function starts to
operate.
Depending on the subject, the color balance
may appear to change slightly . This is not a
malfunction.
This product uses auto white balance. When
most of a subject is red, blue-green areas
may appear bluish; blue areas may appear
orange; and yellow areas may appear bluepurple. In such cases, use the color balance
image quality setting to adjust the color
matching.
Image size and position
change spontaneously.
Focus is not accurate. The autofocus may not be accurate in dark
This sometimes appears to be the case when
multiple operators and administrators have
access to one VN-C3WU unit and change the
settings because the last settings made will
still be in effect for the next user.
places and in locations without features, such
as a wall, etc. In such cases, adjust the focus
manually.
Focus may be slightly off when adjusted
manually at the TELE setting. This is not a
malfunction.
Due to its principle of operation, autofocus is
difficult with striped subjects.
