9.5.1 Exposure Screen
The Exposure screen is used to configure lens settings and exposure modes. The exposure is the amount
of light received by the image sensor and is determined by the amount of exposure by the sensor (shutter
speed), and other exposure parameters.
Administrators may either allow the camera to automatically select an exposure level using a programmed
algorithm or choose the level themselves. The smaller the number (the higher the shutter speed) that the
administrator selects, the lower the exposure level and vice versa.
In Auto Mode , a Minimum Shutter Speed may be set from the drop-down menu to ensure a maximum level
of exposure. In Manual Mode , you can choose fixed shutter speeds from a drop-down menu.
Exposure Mode
The bottom section of the screen enables you to select one of two exposure modes: Auto Mode (default) or
Manual Mode. Administrators may either allow the camera to automatically select an exposure level using
a programmed algorithm or choose the level themselves.

a point where it is insufficient to support the iris setting. A minimum shutter speed may be set from the
drop-down menu to ensure a maximum level of exposure.
The following setting is available:
·
Min Shutter Speed – When selecting this mode, the shutter is completely open and the exposure
priority is given to the iris. Shutter speed and AGC circuit function automatically in cooperating
with the iris to achieve a consistent exposure output.
The shutter speed range is selectable on the drop-down menu from 1/2 to 1/500 sec (NTSC) and
1/1.5 to 1/425 sec (PAL). The following table lists the options.
