I/O Dependencies
These settings allow you to start an I/O when motion is detected, and/or to only
record if a specified I/O is first in a particular state (open or closed.)
Check the required box(es), select the I/O from the drop-down list and finally
select the state the I/O should be in for the condition to be met.
