EI (Electronic iris) function setting
Under normal conditions, set the EI switch to
the EI OFF position and use an auto-iris lens.
However, if you have a manual lens or fixed iris
lens, set the lens aperture to the shortest F stop
and set the EI switch to the EI ON 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 EI switch is set to the
EI ON 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 EI switch to
the EI OFF 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.
• If conditions are outside the electronic iris
operation range or more than the maximum
brightness, it will cause saturation of the
CCD. In that case, use a auto iris lens.
