Function & Setting
Sets the maximum gain of the AGC (Auto Gain Control), which electronically in-
creases the gain when the object is under low light conditions.
OFF : Turns the AGC off.
10 dB : According to the brightness of the object, gain is increased by up to 10 dB
20 dB : According to the brightness of the object, gain is increased by up to 20 dB
SUPER : Use this setting when brightness is still insufficient under the “20 dB”
setting.
This function is used to increase the sensitivity by extending the exposure time.
When the object is dark, this functions sets how high the level of sensitivity will
automatically increase to “x32” means that the sensitivity will be increased continu-
ously up to 32 times the normal level.
Increasing this value slows the shutter speed and motion may appear unnatural.
When the item “SHUTTER” is set to “1/250” or more, the SENSE UP item does not
work and “---“ is displayed as the item name in the CAMERA ALC/ExDR Screen.
Setting values: OFF, x2, x4, x8, x16, x24, x32
When an object is dark, this functions sets whether priority during monitoring is
placed on maintaining the motion of the camera or on picture quality.
MOTION : Motion of the camera is given priority. When an object is dark, the
AGC function is prioritized. This setting is suitable when objects are
characterized by quick motion.
PICTURE : Picture quality is given priority. When an object is dark, the SENSE UP
function is prioritized. This setting is suitable when picture quality is
important.
The ExDR function synthesizes pictures captured at a shutter speed of 1/100 and
those captured at higher shutter speeds to help monitor objects having large differ-
ences in brightness levels.
When the “SHUTTER” function is set to “1/250” or a higher, this function does not
work and “---” is displayed as the item name in the CAMERA ALC/ExDR Screen.
OFF : Turns the ExDR function off.
ON : Turns the ExDR function on.
●
When the item “B&W” is set to “AUTO”, [SUPER] is displayed when the item “AGC MODE”
is set to “SUPER”, and [20 dB] is displayed for other settings. Increase the gain up to the
value displayed.
● Note that increasing gain affects picture quality.
● When the “SUPER” setting is used, the AGC operation may take a while to adjust to
sudden drastic changes in the brightness level.
MEMO
● As the setting of the “SENSE UP” function is increased, the picture may become rough
and whitish, and subject to white blemishes. This is not a malfunction.
● When the setting of the “SENSE UP” function is not OFF, flicker may appear on the
screen under fluorescent light or mercury lamps. This is due to the principles of the
SENSE UP, and is not a malfunction.
● There may be cases where flicker can not be reduced even under the following condi-
tions: 1) Shutter speed is set at 1/120 in areas where the commercial electric current
frequency is 50 Hz. 2) The shutter speed is set at 1/50 in areas where the commercial
electric current frequency is 60 Hz..
MEMO
● When the “AGC MODE” and “SENSE UP” functions are both set to “OFF”, this function
does not work and “---” is displayed as the item name in the CAMERA ALC/ExDR Screen.
● When item “B&W” is set to AUTO, item “PRIORITY” is set to the MOTION priority mode
and “---” is displayed.
MEMO
● When the ExDR function is on, flicker may appear on the screen under fluorescent light
or mercury lamps. This is due to the principles of the ExDR, and is not a malfunction.
● There may be cases where flicker cannot be reduced even under the following condi-
tions: 1) Shutter speed is set at 1/120 in areas where the commercial electric current

electric current frequency is 60 Hz.
