To make a highlighted section of the object easy to view: Decrease the level.
Setting values: –5 to NORMAL to 5
This function sets the color modes to color or B&W.
When switching the mode between “color” and “B&W” is carried out, the focus may

ject is bright and to B&W mode when it is dark.
ALARM IN 1 to 4 : The camera switches to B&W mode when there is an alarm
input from terminals Alarm 1 to Alarm 4.
The B&W mode is set to ON when the contact is shorted (makes

When the “B&W” function is set to “AUTO”, this function sets the signal level of the
object at which the camera will automatically switch to B&W mode.

is low.
NORMAL : The camera switches to B&W mode when the signal level of the object
is normal.
HIGH : The camera switches to B&W mode when the signal level of the object
is high.
Use this function to set the type of light illuminating the object in the B&W mode.
NORMAL : Setting for normal lighting.
IR
: Setting for using IR lighting.
●
When the difference in brightness between objects is large, the picture may not change
even when the ExDR LEVEL is varied. This is due to the characteristics of the camera
and is not a malfunction.
●
When the item “SHUTTER” is set to 1/250 or higher, “---“ is displayed and the settings to
the item “ExDR LEVEL” cannot be carried out.
● When the item “ExDR MODE” is set to OFF, the settings for the item “ExDR LEVEL”
cannot be varied.
MEMO
When the item “B/W” is set to other than AUTO, “---“ is displayed and the settings to the item
“LEVEL” cannot be varied.
MEMO
●
To ensure switching between the color and B&W modes:
Setting item “B&W” to AUTO allows the color and B&W modes to be switched according
to the brightness of the object. However, this switching may sometimes not occur de-
pending on the lighting condition and viewing angle.
To ensure the switching, it is recommended to connect the signal from an external sen-
sor (to be purchased separately by the user) to one of the ALARM input terminals of the
camera and perform switching according to the sensor signal.
●
In order to prevent hunting do not set the item “B&W” to AUTO when using an infrared
lamp.
MEMO
MEMO
If the IR setting is used under ordinary sunlight or fluorescent light, the switching between
the color and B&W modes will not be performed correctly.
