## Abstract

A system and method for installing security cameras on a security network of a security system. The security cameras include an autofocus routine, manually adjustable lenses, and feedback mechanisms. The autofocus routine calculates the degree to which the field of view is out of focus and the feedback mechanism provides feedback to the installer during installation. In response to the feedback from the feedback mechanism, the installer manually adjusts the lens of security camera.

## Claims

### Claim 1

A security camera comprising: a security camera body;
a lens installed within a lens body, the lens body being coupled to the security camera body;
an imager chip on which the lens forms an image;
a focusing mechanism to adjust focus of the lens,
a controller of the security camera executing an autofocus routine, the autofocus routine analyzing an image captured by the imager chip and determining a degree to which the image is out of focus;
a feedback mechanism providing feedback corresponding to the degree to which the image is out of focus for an installer enabling the installer to adjust the focusing mechanism based on the feedback; and
a workstation having a graphical user interface tool that allows an operator to designate a portion of the image from the security camera as an area of interest, wherein the feedback mechanism provides the installer with indications of the degree to which the area of interest is out of focus.
