the monitor. The longer you press the zoom in/out button, the more

noticeable will be the response.

Focusing the Camera

Focus refers to the process of adjusting the clarity of a scene or an object, as

seen through a camera. To adjust the focus on the object or scene displayed

on the monitor, press a focus button. You can either focus near (if the object

is closer than the current focus setting) or far (if the object is farther away

than the current focus setting). You will see the scene on the monitor become

either sharper and clearer or fuzzier and less clear. Like the zoom buttons, the

focus buttons react based on the length of time it is pressed; the longer you

press the button down, the more noticeable will be the response.

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 picture on the monitor be

even 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 make the picture brighter, press the Iris Open button. To make the

picture darker, press the Iris Close button.

To return the iris to its default setting, press both iris buttons simultaneously.

“Flipping” the SpeedDome

You can flip a SpeedDome 180° in the opposite direction. The SpeedDome

flip is especially useful when you are tracking a subject who walks directly

under the SpeedDome and then continues walking on the other side of the

SpeedDome.
