■Full-range scan: If selected, the auto focus scan will be performed throughout the complete range of focus. The full-range scan takes a longer time to complete. A full-range scan usually takes approximately 3 minutes or longer.

■Fully-open Iris: By default, this checkbox is selected for performing an auto scan and should provide an optimal scan result.

Focus window:

By default, the optimal focus is found on a full view window. You may designate a custom window within your current field of view to acquire the best focus out of it. However, you can not place a focus window on a distant background, e.g., a hall way that stretches away for 3 meters or farther. Doing so you will not benefit from the Focus window function.

■Full view: The focus tuning takes place by referring to the full view.

■Custom: You can create a focus window and drag it to a place of interest in your view window.

Note that it is recommended to use this function only when you have a solid object in your view window that is showing a consistent color or texture. This function will not take effect if you set the focus window on a distant background.
