Descriptions
SHUTTER
AUTO
. SHUTTER is recommended to set to AUTO instead of /50s (/60s) for .3MP
ver. and /5s (/30s) for MP ver. if auto iris lens is equipped.
. Set to FLK (Flickerless mode) if TV system is US but power is 50Hz.
The sensitivity will be lower about 30% at low light in FLK mode.
3. AUTO - Shutter varies linearly between /50s(60s)~/50000s for .3MP ver.
and /5s(30s)~/50000s for MP. AUTO shutter mode combined with auto iris
lens may extend the dynamic range but it is NOT recommended due to the
cause of horizontal colour bar noise for the bright scene under florescent or
similar lights.
4. At x~x30, DSS (Digital Slow Shutter) is operating at the selected frame
integration rates regardless of the light level.
DC lens must be used for these settings to get a proper video level.
. SHUTTER should be set to AUTO to get a proper video level with the automatic
shutter if a fixed iris lens is equipped.
. Shutter varies linearly between /50s(60s)~/50000s for .3MP ver. and
/5s(30s)~/50000s for MP.
3. Color rolling or Video level hunting under Fluorescent or similar lighting may
occur in this configuration.
4. Any other fixed shutter settings are not recommended with a fixed iris lens.
AGC
20
AGC default is
20
and can be set between ~ 3.
When AGC is equal to or lower than 3, DAY/NIGHT function becomes disable and
changes to COLOR mode forcibly if DAY/NIGHT was AUTO mode.
Other DAY/NIGHT mode such as EXT, COLOR, B/W keeps its mode and does NOT
change even though AGC is lower than 3.
SENS-UP
AUTO
SENS-UP here stands for the maximum limit of integration rate of frame by DSS
(Digital Slow Shutter) operation in the low light.
If set to AUTO, maximum integration limit for SENS-UP can be set to x, x4, x6, x8,
x0, X5, x0 or x30 in SENS-UP menu.
The integration frames vary automatically within the maximum limit
according to the light level when light becomes low and SENS-UP is AUTO.
The higher sens-up rate, the higher sensitivity but the slower refresh rate.
Some white dots may appear by sense-up due to the long accumulation by a long
shutter period.
BRIGHTNESS
30
Controls the brightness of video.
The higher value, the brighter video.
Brightness is adjusted by controlling the iris for the auto iris lens or the shutter
speed for the fixed iris lens.
D-WDR
OFF
D-WDR enhances the brightness at dark area of the scene by increasing the the
gain partially.
White spot noises may increase in the dark area if it is set to too high.
DEFOG
OFF
Enhances visibility at foggy scene. The performance is very limited.
This function does not work with the clean scene.
BACKLIGHT
OFF
OFF, BLC and HSBLC are available.
(See BLC & HSBLC menus at 6.3. & 6.3. for detail)
