2. GENERAL DESCRIPTION
The C-CV24-2 Color Dome Camera is an indoor-use camera and is equipped with a high-resolution camera
and lens. It is designed to operate on 24 V AC or 12 V DC, which are supplied by an external power supply
unit. Since its 2X vari-focal, auto-iris lens is built inside the camera, its angle of view can be manually
adjusted.
3. HANDLING PRECAUTIONS
• Do not point the camera toward the sun or other strong lighting or reflected light.
• Avoid jarring or striking the camera, as the camera may fail.
• Install the camera in locations where the temperature range does not exceed –10°C to +50°C, and no dew
condensation is formed.
• To clean, wipe with a soft, dry cloth. Never use benzene, thinner or chemically-treated towel to avoid
damage to the camera’s finish.
• To clean the lens, use a camera blower or lightly wipe with lens cleaning paper.
• Picture quality may suffer if camera cables are wired close to other electrical equipment, such as fluorescent
lamps. In such cases, reroute the wiring.
• Monitor screen pictures may become distorted or roll if the camera is used in locations influenced by strong
electrical or magnetic fields from television transmission antennas, motors or transformers. In such cases,
install the cables inside sheet steel cable conduit.
• Do not install the camera in locations where solvents or chemicals are used, as exposure to such chemicals
could damage the dome cover finish.
• Use the external power supply unit of the following rating when the camera is operated on 12 V DC.
12 V DC, over 1.0 A

2. Connect the coaxial cable to the Video output Terminal, and the power supply cable to the Power Input
Terminal.
3. Mount the camera to the ceiling or wall using 2 mounting screws.
Because the mounting screws are not supplied with the camera, prepare appropriate screws for the
application. (Use screws that are over 4 mm in nominal diameter and longer than 25 mm.)

7. ADJUSTMENT
1. Switch on the camera power after completing camera connections.
Power is supplied to the camera.
2. Normally,set the Shutter Speed switch to "1/60"(NTSC) or "1/50"(PAL) position.
Flickering of the picture may interfere with the view under fluorescent lamp in the area with power frequency
of 50 Hz(NTSC) or 1/60(PAL). In such cases, set the switch to "1/100"(NTSC) or "1/120"(PAL) position, and
the image free from flickering can be obtained.
Note
If the Shutter Speed switch of the Mode Setting switch is set to the ON position, sensitivity is reduced
compared to operation in the OFF position. When using the camera in a dark location, or where light flicker is
not an annoyance, set the switch to the OFF position.
3. Connect the monitor to the Monitor Output terminal to permit a picture to be viewed on the monitor.
4. Adjust the camera angle.
Camera angle can be adjusted for up to 130º(± 65º) for horizontal rotation, for up to 140º(± 70º) for vertical
rotation, and for up to 180º(± 90º) for picture tilting.
Horizontal rotation ± 65º
Vertical rotation ± 70º

5. Adjust the angle of view with the Zoom ring and adjust the focus with the Focus ring for the best possible
picture reproduction. After lens adjustment completion, tighten both the Zoom ring fixing screw and the
Focus ring fixing screw.
Notes
• Since the Iris control is factory-preset to an optimum position for general use, avoid tampering with it in
normal conditions. Turning the control unnecessarily could cause reduced picture quality or equipment
failure. When the Iris control needs to be readjusted to match a specific subject, first set both the Adjustment
switch and the Backlight Correction switch of the Mode setting switch to the OFF position, then adjust the
control to an optimum level. After adjustment, place a hand over the lens for several seconds and then
release to check the lens for correct iris operation.
• If the focus is adjusted for a subject under good lighting conditions, the subject may go out of focus when
conditions become dark. To avoid this, adjust the lens focus after setting the Adjustment switch of the Mode
setting switch to the ON position. Be sure to switch it back to the OFF position after completing lens
adjustment.
6. Attach the dome cover to the camera after completing all necessary adjustments.

8.1. Adjustment Switch
Set this switch when adjusting the lens focus.(Provides the same effect as when using the ND filter.)
OFF ON
Standard position :
Set to OFF after lens adjustment completion. Set to this position during normal use.
OFF ON
Adjustment position (during adjustment) :
Use this position when focusing the lens. If the focus is adjusted for a subject under
good lighting conditions, the subject may go out of focus when conditions become
dark. Set the Adjustment switch to ON only when performing focus adjustment.
Note: The color of the screen may periodically vary under fluorescent lighting when the
Adjustment switch is set to ON.
8.2. Backlight Compensation Switch
Set this switch so that the subject is not displayed in black when backlit.
OFF ON
Standard position :
Set to this position during normal use. Backlight Compensation function does not
operate when the switch is set to this position.
OFF ON
Backlight Compensation position (when backlit) :
This position prevents images from being displayed in black when the image is
backlit.
8.3. Shutter Speed Switch
Set this switch to the ON position when annoying screen image flicker is detected.
OFF ON
Standard position :
Set to this position during normal use.
Shutter Speed position :
OFF ON
Annoying screen flicker may result under fluorescent lighting in areas operating with a
power frequency of 50 Hz (NTSC) or 60 Hz (PAL). In such cases, set the Shutter
Speed switch to the ON position to permit a flicker-free picture to be viewed.
Note: If the Shutter Speed switch is set to the ON position, sensitivity is reduced compared
to operation in the OFF position. When using the camera in a dark location, or where
light flicker is not an annoyance, set the switch to the OFF position.
