PREFACE
Panasonic's WV-BP120 series cameras introduce a
new level of high picture quality through the use of a
1/3 inch interline transfer CCD having 512 horizontal
pixels (picture elements). High performance-to-cost
ratio is achieved through the use of newly developed
Sync IC’s and ability to shoot indoor scenes with a
fixed iris lens by use of Electronic Light Control (ELC)
function.
FEATURES
Minimum illumination of 0.15 Ix at F1.4 and Signal-
to-noise ratio of 46 dB by employing a 1/3 inch
interline transfer CCD image sensor with 512 (H) x
492 (V) pixels.
380 lines of horizontal resolution
Either optional standard C-mount or Special C-
mount (CS-mount) auto iris control lens can be
used with.
Selectable auto iris control signal for the lens
either a video signal or DC control signal.
Line-locked Sync or switchable Multiplexed Verti-
cal Drive (VD2) automatically.

‘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.
Refer servicing to qualified service personnel.
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 ever the camera do
becomes wet. Turn power off and refer servicing
to qualified service personnel. Moisture can dam-
age the camera and also create the danger of
electric shock.
¢ Never face the camera toward the sun.
Whether the camera is in use or not, never face it
toward the sun. Do use caution when operating
the camera in the vicinity of spot lights or other
bright lights and light reflecting objects.
Do not operate the camera beyond its
temperature, humidity or power source ratings.
Do not use the camera in an extreme environment
where high temperature or high humidity exist.
Use the camera under conditions where tempera-
tures are within —10°C - +50°C (14°F - 122°F), and
humidity is below 90%. The input power source is
120V AC 60 Hz for WV-BP120 or 24V AC 60 Hz for
WV-BP 124.
Caution:
To prevent fire or shock hazard, the UL list-
ed wire VW-1, style 1007 should be used for
the cable for AC 24V Input Terminal.

See pages 9, 10, 11 and 12 for details on lens
selection.
Flange-back Adjusting Ring
This ring is used to adjust the back foca! length or
picture focus by rotating this ring to clockwise. for
C-mount lens or counterclockwise for special C-
mount (CS-mount) lens.
Caution:
1. Always set this ring to fully clockwise before
mounting the lens.
2. Do not turn this ring too much to counterclock-
wise when the C-mount lens is mounted as
this could damage the inner glass and CCD
image sensor.
Camera Mounting Screw Hole
This threaded hole (1/4" - 20) is used to mount the
camera onto a mounting bracket or tripod.
Auto Iris Lens Connector
This 4-pin female connector supplies the power
and either video signal or OC control signal to the
auto iris lens.
-5-
(5)
A 4-pin male connector, which can be mated with
the camera's female connector, is supplied as a
standard accessory {Part No. YFE4191J100).
This male connector can be installed on lenses
which have incompatible type connector.
See page 13 for installation details.
Lens Selection Switch (ALC (DC/VIDEO)), ELC
This switch is used to select the supplied auto iris
control signal to the lens from the Auto iris lens
Connector.
DC: .
Choose this position when the auto iris control
lens requiring DC control signal such as WV-
LA2.8, WV-LA4R5C3A, WV-LA6B2, WYV-
LASC3A, WV-LZ61/10, WV-LA1262, WV-LA18,
WV-LA36, WV-LA4510, WV-LAGO8, WYV-
LA1208, WV-LZ81/6A, WV-LZ81/10, WV-
LZ783/6, is mounted on the camera.
VIDEO:
Choose this position when the auto iris control
lens requiring video signal such as WV-LA8B,
WV-LA16B, WV-LA25B, WV-LA5OB, is mount-
ed on the camera.

AC Power cord
Video Output Connector (VIDEO)
A 1.0 V[p-p] 75Q composite video signal is provid-
ed at his connector.
AC 24V In Terminal (AC 24V iN)
This terminal accepts 24V AC power source
(19.5V - 28V). Be sure to connect grounding lead
to the GND terminal.
Cautions:
1. Connect this to a 24V AC class 2 power sup-
ply only.
2. To prevent fire or shock hazard, the UL listed
wire VW-1, style 1007 should be used for the
cable for AC 24V Input Terminal.
ELC (Electronic Light Contro}) pea
In this mode a continuously variable slectronic shutter
is employed to automatically control exposure times in
the CCD Image Sensor, according to the incoming
light level. With this mode selected, fixed or manual iris
lens can be used instead of an ALC type lens.
Cautions:
ii,
Under bright conditions such as outdoors, use an
ALC type lens as the ELC contro! range is not wide
enough under these conditions.
. Under certain unique tighting conditions, the fol-
lowing may appear :
Strong smear and/or blooming on high light
objects such as spot lights or windows.
Noticeable flicker on the picture.
Should these phenomena occur, use an ALC lens
. When using in the ELC mode with a fixed iris lens,
the depth of field of the image may be less than
that obtained by using an ALC lens. Depth of field
varies inversely with the iris opening. Thus, using
this camera in the ELC mode with the fixed' iris
lens fully opened will result in less depth of field
than if an ALC lens was used. (And distant objects
in the picture might not be in focus).

CONNECTIONS
Power Source
@ WV-BP120
Connect the AC Power Cord to a electrical outlet of
120V AC 60 Hz.
@ WV-BP124
1, A power supply of 24V AC 60 Hz is required.
2. Connect the power cable to the 24V AC In
Terminal on the rear panel of the camera.

Video Cable
1. lt is recommended to use a video monitor whose
resolution is at least equal to the camera's.
2. Terminate the camera output with 75Q resistor at
the furthest end of its cable run.
e It is recommended to use 75Q coaxial cable.
« Always set the last monitor’s termination switch to
75Q, and set the termination switches of intermedi-
ate monitors to high impedance (Hi-Z) position.

e The maximum extensible coaxial cable tength
between the camera and the monitor is shown in
the table 1. Since cable quality varies among man-
ufactures, verify video quality before final instaila-
tion if maximum lengths are to be used.

3. Wiring precautions:
¢ Do not bend coaxial cable into a curve whose
radius is smaller than 10 times the cables diame-
ter.
e Never staple the cable-not even with circular sta-
ples. Mismatching will occur.
e Never crush or pinch the cable.
All of these will change the impedance of the
cable and cause poor picture quality.
