14 Auto Focus Lens Zoom & Focus Adjustment

The auto focus lens greatly reduces installation time allowing for remote zoom

and one-touch focus control for sharp images. From a remote computer fine

lens adjustments can be made eliminating the need for manual zoom and focus

adjustments at the camera. Zoom sets the field-of-view, and focus sets the

focal point of the scene.

1. When using an Alliance-pro camera with auto focus lens, browse to the

camera’s home page and go to the Setup > Zoom / Lens tab shown in

Figure 14.1.

2. The field-of-view of the image can be set by using the zoom controls under the

preview video window. The lens is set to the widest field-of-view by default, and

is automatically focused. The zoom controls are as follows:

Sets the lens to the full wide field-of-view.

Moves the zoom position toward the wide field-of-view.

Moves the zoom position toward the telephoto field-of-view.

Sets the lens to the full telephoto field-of-view.

3. The lens can be configured to focus automatically or manually. By default, the

camera is in the Auto focus control mode.

a. Auto: After changing the zoom setting on the lens, the lens will focus on

the center of the image after pressing the One-Touch focus button.

b. Manual Focus Mode: Turns off the auto focus mode, and allows the user to

remotely focus the lens using the fine focus adjustments:
