● Flickering of fluorescent lightings can be reduced when the shutter
speed is set to A1/100B or A1/60B respectively in regions of commercial
power frequency 50 Hz and 60 Hz.
● A smear phenomenon specific to CCD, where white bands appear
vertically along bright light source, is more emphasized the faster the

Memo
To ensure a successful B&W/Color switching
● If the [B/W Mode] item is set to AAuto Low, Auto Mid, Auto HighB, the
B&W/Color setting can be switched according to the brightness of the
object, but the condition of illumination and field angle may make this
impossible. To be absolutely certain of B&W/Color switching,
connecting external sensor to alarm input cable of this camera and
setting alarm action of B&W mode is recommended.
When switching the Color mode to B&W mode, the type of light source may
cause the focus to be dislocated. This is because the B&W mode is sensitive to
both visible light and near-infrared light. When this happens, set this item to
AOnB to focus automatically.
On : Enabled.
Off : Disabled.
This item sets the illumination of the object during B&W mode.
Normal : Select this for normal illumination.
IR : Select this when using infrared illumination.

Memo
● If AIRB is set under normal sunlight or fluorescent lighting, the camera
will not switch normally from Color to B&W mode.
