2. GENERAL DESCRIPTION

The C-CV202-3 Color Dome Camera is an indoor-use camera and is equipped with a high-resolution camera and lens. It is designed to operate on 12 V DC, which is 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 direct the camera lens to the sun or strong lighting or light reflection.

Do not give the camera a great shocks or vibration, as this will damage the camera.

It is recommended that the camera be always used in locations where the ambient temperature ranges from -10°C to +50°C and humidity levels of less than 90% to ensure that no condensation is formed.

To clean, wipe with a dry soft cloth. Never use benzene, thinner or chemically processed towel as the unit's plastic or other parts may be deformed or discolored.

When dust has settled on the camera's lens, lightly clean using a commercial camera blower or cleaning paper.

Installing the camera cables in close proximity to fluorescent lamps or other electrical appliances can downgrade the picture quality. In such cases, change the wiring.

If there is a strong electric or magnetic field near the camera, such as television transmission antennas, motors or transformers, this may distort or roll the monitor picture. In such cases, run the entire wiring route through metal conduit tubing.

Do not install the camera in locations where solvents or chemicals are used as the camera's dome cover may be deformed or discolored.

Use the external power supply unit of the following rating. 12 V DC, over 0.5 A

3.Connect the coaxial cable to the Video output terminal, and the power supply cable to the power input cable.

Match the polarities when connecting the power supply cable to the power input cable.

The red cable of the power input cable is positive, while the black one of that is negative.

Apply a self adhesive insulating tape both at the power supply cable connection with the power input cable, and BNC connection.

4.Mount the camera section to the ceiling 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.)

5.Attach the dome cover to the camera section after completing all necessary adjustments.

Insert the dome cover to the camera section, then turn it clockwise until it locks into place.

After attaching the dome cover, fit it using a supplied dome cover fixing screw.

When detaching the dome cover, first remove the screw, then detach the dome cover.

Note

Do not forcefully tighten the screw. Extreme force is applied to the screw and the screw could not be removed, as this may cause the dome cover not to become detached.

6.ADJUSTMENT

1.Switch on the power supply of 12 V DC after completing camera connections.

The power is supplied to the camera.

2.Connect the monitor to the Monitor Output terminal to permit a picture to be viewed on the monitor.

Note

When the monitor output terminal is connected, a video signal cannot be output to the video output terminal.

3.Set the Shutter Speed switch to ON if light flicker is annoying.

Light flicker may interfere with the view under fluorescent lamps in the area where power frequency is 50 Hz. In such cases, set the Shutter Speed switch to "ON" position, and the image free from flickering can be obtained.

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.

4.Adjust the camera angle.

Camera angle can be adjusted for up to 60°(± 30°) for horizontal rotation, and between 0 °and 70° for vertical rotation.

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.

Attach the dome cover with its projection aligned

Notes

Since the Iris control (for sensitivity adjustment) 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 Compensation 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 to the ON position. Be sure to switch it back to the OFF position after completing lens adjustment.
