Note for Adjusting Focus and

When adjusting the Focus and Zoom Screws (on Box Camera, IR Arctic
Box Camera, Mini Fixed Dome, Bullet Camera, Vandal Proof IP Dome and
Fixed IP Camera), please do not over tighten the Focus and Zoom screws.
The screws only need to be as tight as your finger can do it; don't bother
using any tools to get them tighter. Doing so can damage the structure of
lens.
For example,
