Firstly,
you
might
not
even
hear
the
intercom
signal
from
the
remote
indoor
station.
Second,
if
you
do,
you'll
find
yourself
rushing
to
the
station
so
you
may
attend
to
the
guest
in
a
timely
fashion.
This
will
also
happen
more
often
than
you
wish
with
only
one
or
two
indoor
video
stations
installed.
If
you
have
a
patio,
backyard,
how
about
picking
the
calls
from
guests
standing
at
your
door
while
you
are
there?
Also
when
you
are
on
the
phone
somewhere
else
in
the
home,
that's
one
of
the
times
that
you
will
certainly
not
hear
a
possible
guest
call
from
your
video
intercom
station.
Whatever
you
do,
you
can
never
put
your
guests
in
front
of
two
call
buttons!
They
won't
know
which
one
to
hit.
Therefore
for
your
door
monitoring
system
to
be
practical,
you
need
to
be
able
to
readily
hear
door
alerting
tones
from
anywhere
in
your
home,
whether
you
are
on
the
phone
or
not,
and
pick
a
handset
for
a
reply
anywhere
you
might
be.
See
how.
