Adjusting Zoom Settings
Zoom refer to the adjustment of the magnification of the camera lens to make an
object appear closer (larger) or farther away (smaller). The zoom buttons are located
to the left of the Tracker Ball. By pressing the Zoom In button, the camera’s image
appears to move closer to the object. By pressing the Zoom Out button, the camera’s
image appears to move away from the object. If you quickly press and release a zoom
button, only a slight visible change appears on the monitor. The longer a Zoom button
is pressed, the more noticeable the response.
Adjusting Focus Settings
Focus refers to the process of adjusting the clarity of a scene or an object, as seen
through a camera. The focus buttons are located to the right of the Tracker Ball. If the
object that you want to see clearly is farther away than the current focus setting, press
the Focus Far button. If the object that you want to see clearly is closer than the
current focus setting, press the Focus Near button. You will see the picture on the
monitor become either sharper or more distorted. Like the zoom buttons, the focus
buttons react based on the length of time the button is pressed. The longer a focus
button is pressed, the more noticeable the response.
Controlling Iris Settings
Normally, the camera's auto gain function and the auto/manual iris function control
the brightness of the picture. Occasionally the darkness or brightness of the image
displayed on the monitor requires adjustment. The iris control buttons regulate the
brightness or darkness of the image.
To brighten the picture, press the Iris Open button. To darken the picture, press the
Iris Close button. The Iris Open and Iris Close buttons are located to the right of
(Camera button).
