Note
• You cannot set the DNR to ‘ON’ or ‘OFF’ when the AGC mode of the EXPOSURE
menu is ‘OFF’.
• When adjusting the noise reduction level of the DNR mode, remember that the higher the
level set, the more the noise level will be reduced but that after image may also occur.
Day & Night
You can display pictures in colour or black and white.
1. When the SETUP menu screen is displayed, select ‘DAY/NIGHT’ by using the Up and Down buttons
so that the arrow indicates DAY/NIGHT.
2. Select a desired mode using the Left and Right buttons according to the picture
display you want.
●
COLOR: The picture is always displayed in colour.
●
B/W: The picture is always displayed in black and white.
●
AUTO: The mode is switched to Colour in a normal environment, but switches to B/W mode when
ambient illumination is low. To set up the switching time or speed for AUTO mode, press the SET
button.
●
EXTERN: This mode allows you to apply a desired filter to external signals.
Note
• When using a Video Auto Iris Lens, if you set the lens level to low, automatic switching between Color
and Black & White may not occur.
• You cannot control the DAY/NIGHT menu when AGC in the EXPOSURE menu is ‘OFF’.
At this time, the exchange between DAY mode and NIGHT mode operates as like selecting ‘COLOR’
mode.
• The OSD key does not work for 3 seconds when switching to Colour or B/W, to ensure stable camera
operation.
• The camera may focus less well under infrared illumination than under normal illumination.
• Since the camera may not focus as well under infrared illumination at night as it does under normal
illumination, install an Extra-low Dispersion Lens to obtain sharp pictures.
