Controlling Zoom and Focus
Control the zoom and focus settings of the selected camera by pressing the Zoom and
Focus buttons. Figure 3-6 illustrates the locations of these buttons.
Figure 3-6: Zoom and Focus buttons
Zoom refers to adjusting the magnification of the camera lens to make an object appear
closer (larger) or more distant (smaller). To make objects appear closer to the camera, press
Zoom In. To make objects appear more distant from the camera, press Zoom Out. Quickly
pressing and releasing a zoom button displays only a slight visible change on the monitor.
The longer a zoom button is pressed, the more noticeable is the response.
Focus refers to the process of adjusting the clarity of a scene or an object, as seen through
the camera lens. To adjust the focus setting for the object or scene displayed, press a focus
button. Press Focus Near if the object is closer than the current focus setting. Press
Focus Far if the object is more distant than the current focus setting. The scene on the
monitor becomes either sharper and clearer or fuzzier and less clear. 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 is the response.
