Both
video
control
and
doorbell
chime
functions
are
provided
by
the
module
on
the
same
port.
The
user
must
select
by
programming
which
functions
he
needs
the
port
to
perform.
In
video
control
use,
the
port
will
trigger
a
dry
contact
closure
only
once
on
door
calls
independently
of
which
doorphone
initiated
the
call.
This
contact
closure
will
be
used
to
turn
on
a
video
screen
or
a
video
system
upon
doorphone
calls.
Use
this
port
in
video
mode
for
any
other home
automation
control
function
that
you
might
particularly
need.
