Slow Shutter
When set to “On,” the slow shutter functions automatically in low light conditions. This setting is available only
when the AE mode is set to “Full Auto.” The default setting is Off.
Slow Shutter Limit
With certain settings in low light conditions, the shutter speed slows and the gain is increased. This function allows
you to limit the shutter speed reduction. This helps prevent image shake when shooting a moving subject in low
light conditions.
AE Response
The slow AE Response function allows you to reduce the exposure response speed. By default, optimum exposure
can be obtained automatically within approx. 1 second.
Gain Limit
The gain limit can be set at Full Auto, Iris Priority and Shutter Priority mode. Use this setting when image signal-
to-noise ratio is particularly important. Select the gain limit from the following: 9dB, 12dB, 15dB, 18dB, 21dB, 24dB,
27dB, 30dB, 33dB, 36dB.
Gain
Select the gain from the following: 0dB, 3dB, 6dB, 9dB, 12dB, 15dB, 18dB, 21dB, 24dB, 27dB, 30dB, 33dB, 36dB.
Exposure Compensation
When MODE is set to FULL AUTO, SHUTTER PRI or IRIS PRI, setting EXPOSURE COMPENSATION to ON allows
exposure compensation levels to be set from –10.5 to 10.5. Setting the level to 0 disables exposure compensation.
Level +10.5 is the brightest and –10.5 is the darkest compensation value. When EXPOSURE COMPENSATION is set
to OFF, exposure compensation is disabled.
Iris
Select the iris from CLOSE - F1.8.
Shutter Speed
When video format is set to 720P25, 1080P50, 1080i50, 1080P25 or 720P50, shutter speed can be selected from
the following: 1/1, 1/2, 1/3, 1/6, 1/12, 1/25, 1/50, 1/75, 1/100, 1/120, 1/150, 1/215, 1/300, 1/425, 1/600, 1/1000, 1/1250, 1/1750,
1/2500, 1/3500, 1/6000, 1/10K.
When video format is set to 720P30, 1080i59.94, 1080P29.97, 720P59.94, 1080P59.94, 1080I60, 1080P30, 1080P60 or
720P60, shutter speed can be selected from the following: 1/1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/90, 1/100, 1/125, 1/180,
1/250, 1/350, 1/500, 1/725, 1/1000, 1/1500, 1/2000, 1/3000, 1/4000, 1/6000, 1/10K.
High Sensitivity
In this mode, the maximum gain increases, enabling to obtain a brighter output even in a darker en- vironment.
However, if the gain reaches high level, the image will have a large amount of noise.
Bright Level
The bright control adjusts both gain and iris using an internal algorithm, according to a brightness level freely set
by the user.
White Balance Tab
Cam White Balance
Auto: This mode computes the white balance value output using color information from the entire frame with a
range of values from 2500K to 7500K. This mode is the default setting.
Indoor: Sets the color temperature to 3200K.
Outdoor: Sets the color temperature to 5800K.
OPW (One Push White Balance): The One Push White Balance mode is a fixed white balance mode that may be
automatically readjusted only at the request of the user (One Push Trigger), assuming that a white subject, in cor-
