Adjusting the Cameras Focus
The
DCS-3220
Internet Camera features an interchangeable C/CS-type lens
that can be used for different applications as necessary. It supports rotational
focus control so the lens can be adjusted to focus under normal and stable
conditions to maximize the image quality of the Internet Camera.
To adjust the focus of the lens you will need to turn the lens slowly either clockwise
or counterclockwise until the desired image appears. DO NOT over-turn the
lens in either direction as it will be out of focus. Unless you want to substitute
the lens DO NOT unscrew more than 1.0mm apart from the Fixed Lens Assembly.
To help you get the best image quality, keep in mind that while adjusting the
DCS-3220
’s focus you can preview the image quality from your Web browser.
