camera does not switch to night mode.
– Shutter mode is Manual and Shutter speed is 1/15
second or less.
– Shutter mode is Manual, Shutter speed is 1/30
second or more and Auto gain Max.value is 18 dB
or less.
– Shutter mode is other than Manual and Auto gain
Max.value is 18 dB or less.
• When the camera switches to night mode, hunting

first switches automatically to night mode in dark
conditions, and then switches to Light funnel on if it
gets darker. The camera first switches to Light funnel
off in light conditions, and then switches to day mode
if it gets lighter. (SNC-DM160 / CM120 only)

Light funnel mode (SNC-DM110 / DM160 /
CM120 only)
Light funnel increases the image sensitivity by
combining the charge from adjacent pixels in a CCD. In
this camera, one pixel is produced by a combined charge
equivalent to 2 × 2 pixels on the 1280 × 960 image. This
effect results in a low resolution but the high sensitivity.
The mode combining a summed charge is “Light funnel
on”, and the mode without combined charge is “Light
funnel off”.
Notes
• Light funnel does not work when the followings are
set:
– The image size is JPEG - 960 × 720 : MPEG4 -
OFF or JPEG - 768 × 576 : MPEG4 - OFF.
– JPEG cropping is On.
– SolidPTZ is On.
– Iris open is On.
• You may feel the image resolution is reduced when the
Light funnel is On.
• The image file may not be created correctly during
switching the Light funnel modes.
Light funnel function has the following six modes:
Always off: Always works in Light funnel off.
Always on: Always works in Light funnel on.
Sync with Day/Night (SNC-DM160 / CM120 only):
Switches Light funnel mode linked with the switch
of day/night. This option sets Light funnel off in day
mode, and Light funnel on in night mode.
Auto: Normally works in Light funnel off. It switches
automatically to Light funnel on in a dark place.
Switching timing can be set with the following
parameters.
