Specifications

Hand held focus meters such as the CM-2 Camera Master are also useful in
determining the maximum focus of any scene. They are more accurate than large
screen monitors and much easier to take up a ladder. They display the maximum
focus numerically on an LCD type display. By eliminating the subjective nature of
focus setting, you will insure that all cameras will be set to their maximum focus by
any installer.
An understanding of Depth of Field and the proper setting requirements for
Auto Iris cameras will save you time and reduce the frustration of having to return to
the job site to refocus cameras.
