SETTINGS
■ ■ ■ ■ Iris function setting 1 1 1 1
This should normally be set to the down (AI) position.
Use a manual or fixed iris lens and set the lens aperture to the
shortest F stop. Set the switch
1 to the up (EI) position.
Note: Please refer to the specifications for dynamic range of
the electronic iris.
CAUTION:
• The electronic iris is suitable for normal indoor use. When
the switch 1 is set to the up (EI) position, do not use an
auto-iris lens.
• If used under fluorescent light, the image may flicker. In
such a case, change to incandescent lighting or set the
switch
1 to the down (AI) position and use an auto-iris
lens.
• When shooting bright subjects, pay attention to the light
angle in order to avoid or minimize the smear phenomenon
effect.
When using an auto-iris lens (for indoor/
outdoor use)
Set the switch 1 to the down (AI) position.
CAUTION:
If conditions are outside the electronic iris operation range or
more than the maximum illumination, it will cause saturation of
the CCD. In that case, use a manual iris lens.
■ ■ ■ ■ Gain up setting 2 2 2 2
Switch 2 should normally be set to “NORM”. If the monitoring
location is dark and you would like to increase the luminance
(brightness), set switch
2 to “HI”.
Note: If switch 2 is set to “HI”, the images from the
monitoring location will become brighter, but
interference may become more noticeable.
