10-6. BW
This function lets you switch from colour to black-and-
white picture automatically in low light conditions such
as at night.
1. Move the cursor to BW.
2. Select AUTO1, AUTO2, EXT, ON or OFF using [Left]
or [Right].
The factory default setting is OFF.
AUTO1:
The camera selects black and white mode
if the picture is dark, or colour mode if the picture
is bright enough.
AUTO2:
Applying AUTO1 may cause malfunction
when using a source of near-infrared light at
night because the illuminance changes signifi-
cantly when switching between the colour pic-
ture and a black-and-white picture. This can be
prevented by using the AUTO2 setting to detect
the type of light source.
Notes:
• Because the type of light source is detected
based on information received from the CCD
image pickup element, an object that is con-
stantly moving or has the same colour as its
background may not always be properly recog-
nized. When choosing the AUTO2 mode, make
sure to use a light source having a wavelength of
800 nm or more.
• The object may be out of focus when using a
source of near-infrared light than using the visi-
ble light.
EXT:
Colour picture reverts to black-and-white pic-
ture when an external day/night switching signal
is received (refer to alarm connections).
ON:
Black-and-white mode enabled.
OFF:
Colour mode enabled.
3. Select AUTO1 or AUTO2 using [Left] or [Right].
4. Press [SET].
The AUTO1 or AUTO2 menu appears on the monitor
screen.
5. Move the "I" cursor to LEVEL to select the illumi-
nance level using [Left] or [Right].
The factory default setting is HIGH.
LOW:
Colour picture switches to black-and-white
picture at approx.2 lx.
HIGH:
Colour picture switches to black-and-white
picture at approx.5 lx.
6. Move the "I" cursor for DURATION TIME to set the
switching time using [Left] or [Right].

tem for external sync, select ON to prevent a
