Step 1
Move the cursor to “D&N (IR)” and select the mode from the following.
AUTO1:
Automatically switches between color and black-and-white images in accordance with the illuminance. The black-and-white
mode is selected for dark images, and the color mode is selected for bright images.
AUTO2
(default)
:
Automatically switches between color and black-and-white images in accordance with the illuminance. The black-
and-white mode is selected for dark images, and the color mode is selected for bright images. Opening or closing
IR LED lights can be chosen in this mode.
ON:
Displays black-and-white images. Opening or closing IR LED lights can be chosen in this mode.
OFF:
Displays color images.
Note:
• When “AUTO1” or “AUTO2” is selected, it is recommended to set “AGC” to “ON”.
• If a subject is always moving or the screen is occupied with a uniform color, brightness determination may not be 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.
• When “AUTO1” is selected, to obtain color images, a sufficient level of illuminance (approx. 30 lx or more) is required.
• When “AUTO2” is selected, to obtain color images, a sufficient level of illuminance (approx. 40 lx or more) is required.
Step 2
Press the [SET] button.
→
The “D&N (IR)” 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 performed
from the following.
LOW:
Switches from color to black-and-white images when the ambient illuminance of the camera is less than 1 lx.
HIGH
(default)
:
Switches from color to black-and-white images when the ambient illuminance of the camera is less than 2 lx.
Note:
• When the “D&N (IR)” is set to “AUTO2” and “AGC” is set to “ON (LOW)”, the switching illuminance described above can be satisfied.
• The switching illuminance level varies with subjects, light sources, and lenses.
• The switching illuminance level varies in accordance with AGC setting. (
page 14)
• The switching illuminances described above are reference values. The switching illuminance shall be decided based on the actual
installation environment.
• There may be repeated switching between color and black-and-white images depending on the setting and environment.
Step 4
Move the cursor to “DURATION TIME” and select a time for switching between color and black-and-white images from the following.
2 seconds - 10 seconds (default) - 30 seconds - 60 seconds
