„Differences Between Viewer PTZ and Digital 
PTZ

zoom functions that use the digital zoom function, but they 
have the following differences because they employ 
different operating principles.
Using Control for Admin

[Control for Admin] button to display the Control for Admin 
Panel and perform camera operation and video settings.

zoom operations as well as the speed. 
(1) [Pan/Tilt] button

„Setting the Smart Shade Control
The smart shade control function differs from backlight 
compensation in that only dark areas are brightened while 
bright areas are kept intact. 
(1) [Smart Shade Control]
Set to [Off] or [On]. 
(2) Adjusting the Smart Shade Control
When smart shade control is [On], set one of the 7 
levels from [1] (Mild) to [7] (Strong).
Example: If the background is bright and the subject 
is hard to see, this function brightens dark areas to 
make the subject clearer. 
In comparison to backlight compensation, smart 
shade control can reduce overexposure of bright 
areas. 
Note
 When [On] is selected for smart shade control, the image file 
size increases. 
 When [On] is selected for smart shade control, screen noise 
may increase. If noise is noticeable, lower the control level.
„Setting the Focus
[Auto]  : Automatically focuses on the 
subject.

lights, etc., can be reduced. The shutter speed is 
automatically adjusted according to the brightness 
of the environment in which the camera is used.
[Auto (Shutter-priority AE)]
In this mode, the desired shutter speed can be 
specified.
(2) [Exposure Compensation]
When [Auto], [Auto (Flickerless)] or [Auto (Shutter-
priority AE)] is selected for [Exposure], the exposure 
compensation value desired can be selected from 
nine levels (-4 to +4) using the slider.

set the shutter speed in the range of [1/2 sec] to 
[1/16000 sec] from a pull-down menu.
When capturing a moving subject, selecting a higher 
shutter speed can reduce blurry video capture.
(5) [Aperture] 
If [Manual] is selected for [Exposure], set a desired 
aperture value. 
Moving the slider to the left closes the aperture and 
darkens the image. Moving the slider to the right 
opens the aperture and brightens the image. 
(6) [Gain] 
If [Manual] is selected for [Exposure], set a desired 
gain value. 
Moving the slider to the left decreases the gain 
(sensitivity to brightness) and darkens the image. 
Moving the slider to the right increases the gain and 
brightens the image.
Important
 If it is set in the Admin Viewer, the same focus mode will 
occur in the viewers of other users also. 
 Depending on the lighting used, focus may not be 
maintained when switching between [Day Mode] and [Night 
Mode]. Focus when switching Day/Night Mode can be set in 
the [Day/Night Mode Focus Settings] panel in the Admin 
Viewer (p. 141).
 Setting the shutter speed at [1/1 sec] in manual exposure 
(p. 140) will disable the [Auto] and [One-shot AF] focus 
modes in Control for Admin. Switch the focus to [Manual] and 
adjust it to your subject.
