● Compression Ratio
Set quality of delivered images.  The size of image files (JPEG files)
varies in accordance with compression ratio.
Low compression:
This setting produces highest image quality.  The
file size increases.
Mid-low compression:
Intermediate setting between standard and low
compression rates.
Standard:
Standard setting.
Mid-high compression:
Intermediate setting between standard and high
compression.
High compression:
This setting produces lowest image quality. The
file size decreases.
NOTE
The picture quality and the file size change depending on the conditions of
an object (splendor, resolution, movement).
Size of the files affect the network and smaller file size may increase frame
rate.
● Brightness Adjustment
The camera automatically adjusts the level of brightness of images.
Adjust so that the image level becomes optimum in accordance with
conditions of the object.  Images become brighter higher the level is.
Images are dark lower the level is.
NOTE
The brightness level of images are controlled automatically by adjustment
of  the lens, AGC and slow shutter.
● Mounting Method
Set to install the camera.
Ceiling mount: Suspended on a ceiling
Desktop:
When used on a desk
● Focus Range
Set an focusing range.
Standard: Auto focus is in focus when the distance between the cam-
era and object is more than 3 ft.
Macro:
Auto focus is in focus when the distance between the cam-
era and object is between 0.4 inch and 3ft.
NOTE
Auto focusing is sometimes not possible when shooting through a glass
pane, a flat object such as a wall and moving object.  Achieve focusing of
these objects by manual focusing.
Auto focusing is sometimes disabled due to noise when the AGC function
operates.  Then adjust focusing in the Manual mode.
Auto focusing is sometimes not possible when the object is dark and camera
sensitivity is not low enough.  Then adjust focusing in the Manual mode.
Auto focusing is sometimes not possible with images that are output to a TV
or a personal computer monitor.  Then adjust focusing in the Manual mode.
Focusing to 0.4 inch in the macro mode is possible up to about 3.5 x zoom.
Focusing at a higher magnification will be possible only if the distance to
the object is longer than 3ft.
● AF Detection Area
Center: Set a focus detection area in the center of the screen.
All:
Set the focus detection area onto the entire screen.  Choose
