Zooming In and Out

Zoom refers to adjusting the magnification of the camera lens to make an

object appear closer (larger) or farther away (smaller). To make objects

appear closer, press the Zoom In button. To make objects appear farther

away, press the Zoom Out button. If you quickly press and release a zoom

button, there will be only a slight visible change on the monitor. The longer

you hold down a zoom button, the more noticeable the response will be.

Focusing the Camera

Focus refers to the action of adjusting the clarity of the display on the

monitor. To focus on the object or scene displayed on the monitor, press a

focus button. Press the Focus Near button if the object is closer than the

current focus setting. Press the Focus Far button if the object is farther

away than the current focus setting. You will see the picture on the monitor

become either sharper and clearer or fuzzier and less clear. The focus

buttons react based on how long you hold them down; the longer you hold a

button down, the more noticeable the response will be.

Controlling the Iris

Normally, the brightness and darkness of the picture are controlled by the

camera’s auto gain function and the auto/manual iris function. However,

there may be times when you would prefer to see the image on the monitor

be even darker or lighter. There are buttons on the keypad that enable you to
