Colour CCTV Cameras
Operating Instructions Model No. WV-CP250 WV-CP254E

Panasonic’s WV-CP250/CP254E series digital signal
processing colour CCD cameras introduce a
new level of high picture quality and high resolution
through the use of a 1/3-inch interline transfer
CCD image sensor having 752 horizontal pixels
(picture elements), and digital signal processing
LSI’s. This model offers cutting-edge technology
for advanced video surveillance.


1. The following functions are built in.
(1) Auto Light Control (ALC)/Electronic Light
Control (ELC)
(2) Automatic Gain Control (AGC) and
Automatic Tracing White Balance (ATW)
(3) Camera synchronization mode selectable
between internal (INT), Line-locked
(LL) and Multiplexed Vertical Drive (VD2).

2. Minimum Illumination of 1.0 lx (0.1 foot-candle)
at colour mode, 0.15 lx (0.015 foot-candle)
at black and white mode with F1.4 lens.
3. Signal-to-noise ratio of 50 dB (min)
(at AGC OFF, weight ON)
4. Horizontal resolution of 480 lines
5. Auto iris lens control selectable between
video signal and DC power supply.
6. Auto black-and-white mode enables the camera
to switch between colour and black and
white picture in response to light input.


1. Do not attempt to disassemble the camera.
To prevent electric shock, do not remove
screws or covers.
There are no user serviceable parts inside.
Ask a qualified service person for servicing.
2. Handle the camera with care.
Do not abuse the camera. Avoid striking,
shaking, etc. The camera could be damaged
by improper handling or storage.
3. Do not expose the camera to rain or moisture,
or try to operate it in wet areas.
Turn the power off immediately and ask a
qualified service person for servicing.
Moisture can damage the camera and also
create the danger of electric shock.
4. Do not use strong or abrasive detergents
when cleaning the camera body.
Use a dry cloth to clean the camera when
In case the dirt is hard to remove, use a mild
detergent and wipe gently. Afterwards, wipe
off the remained part of the detergent in it
with a dry cloth.
5. Clean the CCD faceplate with care.
Do not clean the CCD with strong or abrasive
detergents. Use lens tissue or a cotton tipped
applicator and ethanol.
6. Never face the camera towards the sun.
Do not aim the camera at bright objects.
Whether the camera is in use or not, never
aim it at the sun or other extremely bright
objects. Otherwise, blooming or smear may
be caused.
7. Do not operate the camera beyond the
specified temperature, humidity or power
source ratings.
Use the camera under conditions where temperature
is between –10 °C - +50 °C (14 °F -
122 °F), and humidity is below 90 %. The
input power source is 220 V - 240 V AC 50 Hz
for WV-CP250, and 24 V AC 50 Hz or 12 V
DC for WV-CP254E.

4 Mount Adapter
The camera mounting screw hole is for
mounting the camera onto a mounting bracket.
The camera is originally designed to be
mounted from the bottom, however, a topmounting
type is also available. To mount
from the top, remove the mount adapter from
the bottom of the camera by removing two
fixing screws. Attach the mount adapter to
the top as shown in the diagram, then mount
the camera on the mounting bracket. Make
sure that two original screws are used when
mounting the mount adapter; longer type
screws may damage inner components, too
shorter type screws may cause the camera
5  Synchronization Mode Selector (INT, LL)

12 Day/Night Mode Selector
This function switches the condition of pictures
from colour to black and white in low
light conditions.
COLOUR FIX: Colour picture reverts to
black-and-white picture when an external
day/night switching signal is
received (refer to Day/Night connections).
Note: When using this unit with infrared rays
or lighting of which colour temperature is
3 000 K or less, select this mode without
fail, and short-circuit the Day/Night input
terminals if you select the black-andwhite
(The AUTO mode may cause hunting.)
AUTO: The camera selects black-and-white
mode if the picture is dark, or colour
mode if the picture is bright enough.
• When using this unit with a video servo
control lens, you may not switch from the
black-and-white mode to the colour
mode depending on lens iris.
In such a case, operate the lens adjuster
to open the aperture.
• This function may not be activated automatically
when a backlight or a strong
light source causes excessive contrast
in the picture. In such cases, use the
Day/Night input terminals.

13 Duration Time Selector
This selector is available when the Day/night
switch position is 'AUTO'.
Switching time (5 sec. or 1 minute ) is selectable.
14 BW Level Selector
Selects the luminance level.
This selector is available when the Day/night
switch position is 'AUTO'.
According to the luminance level, this camera
automatically switches the condition of picture
from colour to black-and-white, or in
HI: Colour picture switches to black-andwhite
pictures at approx. 7 lx with F1.2
LOW: Colour picture switches to black-andwhite
pictures at approx. 5 lx with F1.2
The factory default setting is HI.

resolution is at least equal to that of the
2. The maximum extensible coaxial cable
length between the camera and the monitor
is shown below.

Installation of Auto Iris Lens
Install the lens connector (YFE4191J100) when
using a video drive ALC lens.
The installation should be made by qualified
service personnel or system installers.
Cut the iris control cable at the edge of the lens
connector to remove the existing lens connector
and then remove the outer cable cover of the supplied

Pin 4: Shield, ground

Solder the lens cable to the pins of the supplied

Mounting the Lens
Before you mount the lens, loosen the focus
lock knob, and rotate it clockwise until it
stops. If the ring is not at the end, the inner
lens or CCD image sensor may be damaged.
q Mount the lens by turning it clockwise on the
lens mount of the camera.
Note: When mounting the C-mount lens on
the camera, mount the C-mount adapter
by rotating it clockwise in advance.
w Connect the lens cable to the auto iris lens
connector on the side of the camera.

Caution for Mounting the Lens
The lens mount should be a C-mount or CS-mount
(1”-32UN) and the lens weight should be less than
450 g (0.99 lbs). If the lens is heavier, both the
lens and camera should be secured by using the
The protrusion at the rear of the lens should be as
shown below.
