SETTINGS

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.
