SHUTTER SPEED
Use this option to set the shutter speed manually.
Select one of the following options: 1/60(NTSC), 1/50(PAL), 1/100(NTSC), 1/120(PAL), 1/250, 1/500, 1/1000, 1/2000, 1/4000, 1/10000, 1/20000,
1/50000. The default is 1/60(NTSC) or 1/50(PAL).
NOTE: This option appears when AUTO EXPOSURE is set to MANUAL.
AUTOMATIC GAIN CONTROL (AGC)
Automatic gain control (AGC) automatically adjusts the image when the light level changes. Most scenes benefit from AGC operation.
Select ON or OFF. The default is ON.
NOTE: You can also use the rear panel button to enable or disable AGC (refer to Quick Setup).
DIGITAL SLOW SHUTTER (DSS (SENS))
Digital slow shutter (DSS) slows the picture frame rate and increases the camera sensitivity under low-light conditions by increasing the number
of fields of integration. Use this option to enable or disable this feature, and to set the number of integration fields.
Select one of the following options: OFF, 2, 4, 6, 8, 10, 20, 40. The default depends on the selected profile (refer to Table G.)
NOTES:
• If you disable SENS on the rear panel, the camera saves the DSS (SENS) value on the EXPOSURE SETTING menu (refer to Quick Setup).
• This option is automatically disabled when AUTO EXPOSURE is set to MANUAL.
• Depending on the number of fields of integration, the picture will develop a granular appearance and motion may lag, resulting in a stereo-
scopic effect or streaking on fast-moving objects.
DAY AND NIGHT
Use this option to specify how the camera will switch between day (color) and night (black and white) operation.
Select one of the following options:
AUTO Select this option to switch the filter automatically as light conditions change.
The D&N DETECTION and D&N FILTER LIMIT settings appear.
The camera switches from day to night when the AGC gain level reaches 22 dB.
It switches from night to day when the AGC gain level reaches 16 dB.
When AUTO is selected, both the angle of view and the lighting conditions may
cause the camera filters to switch constantly. Use the D&N FILTER LIMIT to
compensate for this (refer to Day and Night Filter Limit).
COLOR Select this option to operate the camera in day mode.
BW Select this option to operate the camera in night mode.
EXT. Select this option to use an external signal to switch between day and night modes (refer to Connecting External Control
for more information). The D&N DETECTION and D&N FILTER LIMIT become enabled. In some installations, this option may be
more reliable than AUTO mode.
The default is COLOR, except for the DAY&NIGHT profile, whose default is AUTO.
NOTES:
• You can also use the rear panel button to switch between AUTO and COLOR modes (refer to Quick Setup).
• When AGC is enabled, AUTO and EXT. modes are available. When AGC is disabled, AUTO and EXT. modes are not available; you can select
only COLOR or BW mode.
