Depending on the setting options, the range set by

Visibility Enhancer (VISIBILITY ENHANCER -
SETTING)

In high-contrast scenes such as against a back light,
this function reduces overexposure and
underexposure. Selecting the checkbox enables the
function.

Effect (VISIBILITY ENHANCER - EFFECT)

Set the level of Visibility Enhancer.

Iris (EXPOSURE - IRIS)

Select the iris value from the drop-down list. This
function can be selected only when [Mode] is set to
[Iris priority] or [Manual].

Gain (EXPOSURE - GAIN)

Select the gain from the drop-down list. This
function can be selected only when [Mode] is set to
[Manual].

Auto gain Max. value (EXPOSURE - GAIN LIMIT)

Select the maximum gain value of automatic
exposure control from the drop-down list. This
function can be selected only when [Mode] is set to
[Full auto], [Shutter priority], or [Iris priority].
You cannot set the value lower than [Gain point
level].

Gain point (EXPOSURE - GAIN POINT)

When you set [Slowest] (lower limit of the shutter
speed) to be lower than the output image frame
rate, the shutter speed controls exposure based on
the [Gain point] setting. Normally, when exposure is
adjusted with sensitivity, noise is prominent when
sensitivity is increased to brighten the image. You
can decrease noise by adjusting the exposure
through lower shutter speeds instead of adjusting
with sensitivity. When the exposure is adjusted,
select the checkbox of [Gain point] and set [Gain
point level] to the value of sensitivity position that
exposure is adjusted through shutter speeds. When
shutter speeds reaches [Slowest] for exposure
adjustment, sensitivity will increase again to adjust
exposure. This setting is available when [Mode] is
set to [Full auto] or [Iris priority].

Gain point level (EXPOSURE - POINT POSITION)

This is enabled when the checkbox of [Gain point] is
selected. When sensitivity during exposure
adjustment reaches the value of [Gain point level],
exposure will be adjusted through a lower shutter
speed.
You cannot select a value that exceeds [Auto gain
Max. value].
This setting is available when [Mode] is set to [Full
auto] or [Iris priority] and the checkbox of [Gain
point] is selected.

Shutter speed (EXPOSURE - SPEED)

Select shutter speed from the drop-down list. This
function can be selected only when [Mode] is set to
[Shutter priority] or [Manual].

Note

When you switch to the shutter speed value with a
great change, it may take some time to apply the
setting value.
During that time, the setting value on the display
does not match with the actual setting value. By
reloading the web browser, the correct setting value
is displayed.

Fastest (EXPOSURE - MAX SPEED)

Set the maximum shutter speed.
This setting is available when [Mode] is set to [Full
auto] or [Iris priority].

Set the minimum shutter speed.
This setting is available when [Mode] is set to [Full
auto] or [Iris priority].

Auto slow shutter (EXPOSURE - SLOW SHUTTER)

Select the checkbox to enable the auto slow shutter
function. This function can be selected only when
[Mode] is set to [Full auto].
