Controlling the Iris
Normally the camera's automatic gain function and the auto/manual iris function control the
brightness of the image. However, there may be times when the scene on the monitor could
be even darker or brighter. The iris control buttons—Iris Close and Iris Open—regulate
the image brightness. Figure 3-7 illustrates the location of the iris control buttons.
