1. SAFETY PRECAUTIONS

Before installation or use, be sure to carefully read all the instructions in this section in order to ensure long, trouble-free operation.

Be sure to follow all the precautionary instructions in this section, which contain important warnings regarding safety.

After reading, keep this manual handy for future reference.

Safety Symbol and Message Conventions

Safety symbols and messages are used in this manual to prevent bodily injury and property damage which could result from mishandling. Before doing anything else, read this section first so you are thoroughly aware of the potential safety hazards as well as understanding the safety symbols and messages.

Do not expose the unit to rain or an environment where it may be

WARNING splashed by water or other liquids, as doing otherwise may result in fire or electric shock.

Indicates a potentially hazardous situation which could result in death or WARNING serious personal injury if ignored or mishandled.

This is a class A product. In a domestic environment this product may cause radio interference in which case the user may be required to take adequate measures.

Use the unit only with the voltage specified on the unit. Using a voltage other than that which is specified may result in fire or electric shock.

Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface. Failure to do so may result in the unit falling down and causing personal injury.

Install the unit only in a location that can structurally support the weight of the unit and the mounting bracket. Doing otherwise may result in the unit falling and causing personal injury.

Do not install the unit outdoors since it is designed for indoor use. If installed outdoors, the aging of parts causes the unit to fall down, possibly resulting in personal injury. Also, when it is exposed to rain, an electric shock may result.

Should any of the following irregularities be found during use, immediately switch off the power, disconnect the power supply cord from the AC outlet and contact your TOA dealer. Do not attempt to further use the unit because a fire or electric shock may result.

If you detect smoke or a strange smell coming from the unit.

If water or a foreign object enters the unit.

If the unit falls or the unit case breaks.

If the power supply cord is damaged (exposure of core or disconnection).

If no image is displayed on the screen.

Do not open nor modify the unit’s case to prevent a fire or electric shock because there are high voltage components inside the unit. Refer all inspection, adjustment and repair work to the dealer from where the unit was purchased.

Do not insert or drop metal pieces or flammable materials into the unit’s ventilation slots as this may result in fire or electric shock.

Have the unit periodically checked by the dealer from where it was purchased. Should the unit or its mounts corrode or structurally deteriorate, the unit could fall down, possibly resulting in personal injury.

Indicates a potentially hazardous situation which could result in CAUTION moderate or minor personal injury, and/or property damage if ignored

or mishandled.

Avoid installing the unit in humid or dusty locations, in locations exposed to the direct sunlight, near the heaters, or in locations generating sooty smoke or steam as doing otherwise may result in fire or electric shock.

Leave the unit’s installation to the dealer from where the unit was purchased because the installation requires expert knowledge. Inadequate installation may cause the unit to fall, possibly resulting in personal injury.

Do not hang from the unit, as the unit may fall, possibly resulting in personal injury.

When the unit is cleaned or is not used for a long period of time, remove the power supply plug from the AC outlet in order to avoid electric shock or fire.

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

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.

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.
