Controlling Zoom and Focus
Once you have selected a camera, you can control its zoom and focus
settings.
Zooming In and Out
Zoom refers to the apparent action of “moving” closer to or farther away
from an object, as seen through the camera lens. The
Zoom
button is located
to the left of the Tracker Ball. By pressing the Zoom button forward, the
image from the camera appears to move closer to the object. By pressing the
Zoom button back, the image from the camera appears to move away from
the object. If you quickly press and release the Zoom button, there will be
only a slight visible change on the monitor. The longer you press the Zoom
button, the more noticeable will be the response.
Focusing the Camera
Focus refers to the action of adjusting the clarity of the display on the
monitor. The
Focus
button is located on the right side of the Tracker Ball.
To focus the camera on a distant object, press the Focus button forward (if
the object is farther away than the current focus setting). To focus the camera
on a nearer object, press the Focus button back (if the object is closer than
the current focus setting). You will see the picture on the monitor become
either sharper or fuzzier. Like the Zoom button, the Focus button reacts
based on how long you press the button; the longer you press the Focus
button, the more noticeable the response.
Controlling the Iris
Normally, the brightness of the picture is controlled by the camera's auto
gain function and the auto/manual iris function. However, there may be times
when you would like to see the picture on the monitor to appear darker or
lighter. There are buttons on the keypad that enable you to control the
camera's iris, which is the device that regulates the brightness or darkness of
the picture.
To brighten the picture, press the Iris Open button. To darken the picture,
press the Iris Close button.
