
Shutter Priority – Select this mode to set a fixed exposure while other parameters can
change. The shutter speed range is from 1/25 to 1/425 sec (PAL) to 1/30 to 1/500 sec
(NTSC). The default setting is 1/25 (PAL) or 1/30 (NTSC). From the Min Shutter Speed
drop-down list, select one of the following shutter speed options.

Flickerless – This mode is used to eliminate flicker for indoor applications where
fluorescent lighting is used. The darker the ambient lighting, the slower the shutter
speed should be. The shutter speed range is from 1/12 to 1/100 sec (PAL) or 1/15 to
1/100 sec (NTSC). The default setting is 1/12 (PAL) or 1/15 (NTSC). From the Min
Shutter Speed drop-down list, select one of the following shutter speed options.

Manual Mode – Manual mode is used generally where light levels are fixed and the auto
settings do not provide the perfect exposure. It is recommended for scenes such as
indoor scenes, where there is a fixed lighting contrast and a constant, precise exposure
is required.
Manual Mode opens the iris completely with a fixed gain to a fixed shutter speed. Users
can select a suitable shutter speed according to the environmental luminance.
Increasing the value of the fixed shutter increases the amount of light entering the
sensor. This allows a brighter and more detailed image. Similarly, utilizing gain and
increasing its level increases the sensitivity of the image sensor, which brightens the
image and add details. This increases the level of noise in the image.
In Manual Mode, the administrator can select a fixed shutter speed and gain from drop-
down menus. The smaller the shutter speed number (the higher the shutter speed), the
lower the exposure level. The higher the gain, the brighter the picture.
