Make adjustments to the control board and option switches
The control board is a microprocessor-based circuit that controls the on-board sensors and a
two (2) channel video switcher. The main purpose of the switcher is to display the image from
the on-board camera when the PIR detects motion. It may also be directed to ignore the sen-
sor and select one of the two (2) video signals.
