Step 1
Move the cursor to "BW MODE" and select the black-and-white control from the following:
AUTO1 (default):
Automatically toggles between color and black-and-white images in accordance with the screen brightness
(illuminance). The black-and-white mode is selected for dark images, and the color mode is selected for bright images.
AUTO2:
Uses a near-infrared light source at nighttime.
ON:
Displays black-and-white images.
OFF:
Displays color images.
Note:
• The auto back focus function also allows users to correct out of focus when changing between color and black-and-white
images. (

• If a subject is always moving or the screen is occupied with a uniform color, brightness determination may be not performed
successfully because the brightness is merely determined by information from the CCD image sensor. When "AUTO2" is
selected, the wave length of the light source shall be 800 nm or longer.
Step 2
Press the setting button.
→
The "BW MODE" screen appears.
Step 3
Move the cursor to "LEVEL" and select a brightness level at which switching between color and black-and-white images is per-
formed from the following:
LOW:
Switches from color to black-and-white images when the ambient brightness (illuminance) of the camera is approx. 0.3 lx
or less.
HIGH (default):
Switches from color to black-and-white images when the ambient brightness (illuminance) of the camera is
approx. 0.6 lx or less.
Note:
• To obtain color images, a sufficient level of illuminance (approx. 30 lx or more) is required.
• The switching illuminance level varies with subjects, light sources, and lenses.
• The switching illuminance level varies in accordance with AGC setting.
• The switching illuminances described above are reference values. The switching illuminance shall be decided based on the
actual installation environment.
Step 4
Move the cursor to "DURATION TIME" and select a time for switching between color and black-and-white images from the fol-
lowing: (Default: 10 seconds)
2 sec. - 10 sec. - 30 sec. - 60 sec.

Step 5
Move the cursor to "BURST (BW)", and decide whether or not to provide a burst signal output in the black-and-white mode.
ON (default):
Provides a burst signal output.
OFF:
Does not provide any burst signal output.
Note:
• Images may not be displayed appropriately without burst signals when camera images are displayed in the black-and-white
mode depending on a monitor or VCR model to be used. In such a case, set the burst signal output to "ON".
