7.5.1 Exposure

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. Even in Auto Shutter, a Minimum Shutter
Speed may be set from the drop-down menu to ensure a maximum level of exposure. In Manual
Mode, the administrator can choose fixed shutter speeds from a drop-down menu. The smaller the
number (the higher the shutter speed) that the administrator selects, the lower the exposure level
and vice versa. Following is an illustration of the Camera menu.
