PREFACE
The Panasonic WV-CP120 offers anew low end color
camera through the use of a1/3 inch interline transfer
CCD image sensor
Asingle coaxial cable connects the camera and speci-
fied monitor or camera drive unit, and carries four sig-
nals audio, video DC power and vertical drive pulses
This simple system is specially designed for surveil-
lance and security needs at offices, factories, schools,
hospitals public or residential buildings, etc
FEATURES
•Minimum illumination of 05Ix at FO 75 (equivalent
15Ix at F1 4) and signal-to-noise ratio of 46 dB by
a1/3 inch interline transfer CCD image sensor with
512(H)X492 (V) pixels
•Horizontal resolution of 330 lines
•Adjustable video level by auto light control (ALC)
and electronic light control (ELC)
•Built-in automatic gam control (AGC +15dB) and
automatic tracing white balance control (ATW)
•Backlight compensation (BLC) function for shoot-
ing objects when there is interference by back-
ground lighting
•Optional C-mount lens can be used together with
the WV-AD20 optional lens mount converter

PRECAUTIONS
•Do not attempt to disassemble the camera.
To prevent electric shock, do not remove screws
or cover. There are no user-serviceable parts
inside.
Call aqualified service person for repairs.
•Handle the camera with care.
Do not abuse the camera. Avoid striking or shak-
ing it. The camera could be damaged by improper
handling or storage.
•Do not expose the camera to rain or moisture,
or try to operate it in wet areas.
Do take immediate action if the camera becomes
wet. Turn power off and call aqualified service
person. Moisture can damage the camera and
also cause electric shock.
Never direct the camera toward the sun.
Whether the camera is in use or not, never direct it
toward the sun, Do use caution when operating
the camera in the vicinity of spotlights or other
bright lights and light reflecting objects.
Do not operate the camera beyond its tempera-
ture or humidity range.
Do not use the camera in an environment of high
temperature or humidity. Use the camera under
ambient conditions of -10°C -+50°C (14°F -
122°F) in temperature and 90% or less in humidity.

(D Lens (Option)
See pages 9, 10, 11, 12 and 13for details on lens
selection. Astandard C-mount lens can be used
with the camera by adding the optional lens mount
converter (C-mount adapter) WV-AD20.
©Flange-back Adjusting Ring
This ring is used to adjust the back focal length or
picture focus by rotating it.
(D Video Output jack (VIDEO OUT)
This jack is used to adjust the angular field of view
or focus while observing the picture on the moni-
tor.
©Camera Mounting Screw Hole
This screw hole (1/4" -20) is used to mount the
camera onto amounting bracket or atripod.
(D Auto Iris Lens Connector
This 4-pin connector supplies power and the DC
control signal to the auto iris lens.
©Volume Control (VOLUME, MIN/MAX)
The volume control is preset to center position at
the factory. Adjust it to prevent howling.
(7) Video level Control (VIDEO LEVEL, L/H)
This control adjusts the level of auto iris control
when the ALC/ELC Switchi ©is set to ALC posi-
tion, or the level of electronic light control when the
ALC/ELC switch is set to ELC position.
®ATW Balance Control (ATW BALANCE, R/B)
This control adjusts the red and blue color bal-
ance. It is preset to center position which usually
provides accurate color reproduction.
(9) Power Indicator
#Camera Output Connector
This connector is used to connect acoaxial cable
to the CAMERA INPUT of the specified monitor or
camera drive unit, to receive DC power and verti-
cal drive pulse, and supply the audio and video
output of the camera.
©ALC/ELC Switch (ALC/ELC)
This switch is used to choose the lens as follows.
ALC: Choose this position when using an auto iris
lens.
ELC: Choose this position when using afixed or
manual iris lens.

<g> Detail level Switch (SOFT/SHARP)
The detail/aperture level can be chosen by this
switch. Choose the desired position while observ-
ing the picture on the monitor.
Note: Usually choose SHARP position. When a
Quad System is connected to this camera, set
this switch to SOFT position.
©BLC ON/OFF Switch (BLC, ON/OFF)
When backlight affects the picture, set this switch
to ON position for aclearer picture.
®Microphone Switch (MIC, ON/OFF)
Set this switch to ON or OFF as needed.
ELC (Electronic Light Control) Function
In this mode acontinuously variable electronic shutter
is employed to automatically control the exposure
times in the CCD Image Sensor according to the
incoming light level.
Cautions:
1. Under bright conditions such as outdoors, use an
ALC type lens as the ELC control range is not wide
enough under such conditions.
2. Under certain unique lighting conditions, the fol-
lowing may appear
:
•Strong smear and/or blooming on highlight objects
such as spot lights or windows.
•Noticeable flicker in the picture and/or color rendi-
tion variations.
•Periodic variance of white balance
Should these phenomena occur, use an ALC lens.
3. When shooting in the ELC mode with afixed iris
lens, the depth of field of the image may be less
than that obtained with an ALC lens. Depth of field
varies inversely with the iris opening.
Thus, using the camera in the ELC mode with the
fixed iris lens fully opened will result in less depth
of field than if an ALC lens were used. (In addition,
distant objects in the picture might not be in
focus.)

BLC (Backlight Compensation) Function CAMERA SETUP
When strong, unwanted background lighting interferes
with the clarity of important scene objects, turn this
switch to 'ON' position
Cautions
1Setting this switch to "BLC OFF" position is recom-
mended when using the pan/tilt head or when the
illumination of the object changes rapidly, since
the Lens ins speed is slowed in 'BLC ON" posi-
tion
2If the desired objects are not in the center of the
picture, backlight compensation may not work
effectively
Remove the rear cover fixing screw and pull the rear
cover out as shown below
To improve perfomance, select the function switches
located on the back

CONNECTION
Caution: Keep the POWER switch of the specified
monitor, Camera Extension Unit and Camera Drive
Unit in OFF position white making connections. If
the power of these units is ON during connections,
the camera does not function due to the built-in
protection circuit which protects it against wrong
connections.
•Basic System
Connect the coaxial cables between the camera
and CAMERA IN connector of the specified moni-
tor or Camera Drive Unit. The approximate maxi-
mum cable length is as follows:
Coaxial Maximum DC R/1 000 ft. of
Cable Type Cable Lenth Inner Conductor
RG-59/U 200 m(660 ft) Less than 30 Q
RG-6/U 500 m(1,650 ft) Less than 12 Q
The maximum DC resistance between the camera
and these unit is 20 Q.
