Camera Adjustment and Programming

With the exception of the focus and field of view adjustments (made using levers A and B), all

settings for the ZC-DWT4312 camera are made using its onscreen menu display. A functioning

video monitor and a separate plug-in service board (C) are required to view and select

options.
