Camera Control
(1) [Digital Zoom]
Set digital zoom to [Disable] or [Enable].
The higher the digital zoom ratio, the lower the image
quality becomes.
(2) [Image Stabilizer]
Select [Disable], [On1] or [On2] for image stabilizer.
Image stabilizer has the effect of correcting blurry
images. Try [On2] if the image is still blurry after
selecting [On1].
If you have selected [On1] or [On2] as the image
stabilizer setting, the viewing angle will be smaller and
the image more coarse than when [Disable] is
selected. This is not a malfunction.
(3) [AGC Limit]
Select one of 5 levels from 1 to 5 to automatically set
the upper gain limit. The greater the value, the higher
the sensitivity becomes. If you do not want to use the
automatic gain adjustment, select [OFF]. Setting the
[AGC Limit] allows you to record dark scenes without
gain adjustment.
Day/Night
(1) [Mode]
Set Day/Night mode to [Manual] or [Auto].
It is also possible to switch between [Day Mode] and
[Night Mode] using Admin Viewer Night Mode
function (p. 139).
If you have selected [Auto], set [Switching Brightness]
and [Response (sec.)] according to the environment
in which the camera is installed as well as the desired
switching conditions.
(2) [Switching Brightness]
Set the brightness at which [Day Mode] and [Night
Mode] will be switched. Select [Darker], [Slightly
Darker], [Standard], [Slightly Brighter] or [Brighter].
Select [Darker] if you want to capture video in color as
much as possible.
Select [Brighter] to reduce noise. Note that this mode
switches to black & white sooner.
(3) [Response (sec.)]
Set the time in seconds needed for judgment on
switching between [Day Mode] and [Night Mode].
Select [60], [30], [20], [10] or [5].
The mode will switch between [Day Mode] and [Night
Mode] if brightness remains above or below the level
set in (2) for the number of seconds specified.
Select [30] or [60] if brightness changes frequently,
such as when a light source passes in front of the
camera. Select [5] or [10] if change in brightness is
minimal.

than “960 x 540”.
The image stabilizer is not effective when the subject is
shaking.
The image stabilizer is not effective beyond a certain level of
vibration or against momentary vibration.
See “Important” on p. 92, p. 98 for precautionary notes
regarding Admin Tools configuration when image stabilizer is
set.
See “Important” on p. 134 for precautionary notes regarding
the Viewer when image stabilizer is set.
[AGC Limit] is disabled when [Exposure] is set to [Manual] or
[Auto (Flickerless)] in the Admin Viewer.
Minimum subject illumination may change when [AGC Limit]
is set.
Important
If [Auto] is selected for [Day/Night], conduct a thorough
operation test to check the effectiveness of the setting
beforehand.
If [Auto] is selected for [Day/Night], set [Exposure] of the
Admin Viewer to [Auto], [Auto (Flickerless)] or [Auto (Shutter-
priority AE)] (p. 138).
To use with infrared illumination, set [Day/Night] to [Manual].
When Day/Night Mode is set to [Manual], in additional to the
Day/Night function of the Admin Viewer (p. 139), it is also
possible to switch Day/Night Mode via settings in [Setting
Page] > [Event] > [External Device Input] (p. 63) or [Event] >
[Timer] (p. 64).
When [Day Mode] and [Night Mode] are switched, the image
may not focus correctly depending on the brightness.
If [Day/Night] is set to [Auto], the infrared cutoff filter may
move several times while the mode is switching between
[Day Mode] and [Night Mode]. Pan, tilt, zoom and manual
focus will not work during this period.
