Introduction
The
NAV
IP
access
controller
is
a
powerful
Linux
‐
based
controller
with
modular
design.
You
can
add
up
to
4
door
modules
to
the
NAV
controller
for
expanding
the
control
scale
of
up
to
8
doors
/
readers.
Or
you
can
add
one
alarm
module
to
the
NAV
controller
to
manage
up
to
10
alarm
inputs
and
18
alarm
outputs.
Moreover,
each
NAV
controller
can
connect
up
to
31
EverFocus’
Flex
series
controllers
to
expand
the
control
scale
of
up
to
256
doors
/
readers.
You
can
connect
to
the
NAV
controller
via
network
to
remotely
review,
monitor
all
the
events
on
NAV
and
Flex
controllers
and
configure
all
31
Flex
series
controllers
from
the
same
built
‐
in
browser
‐
based
management
software.
Furthermore,
you
can
optionally
install
multiple
NAV
controllers
for
a
larger
scale
access
control
system.
By
doing
so,
you
will
need
the
enterprise
level
Navigation
software
installed
as
a
central
server
to
manage
the
large
access
control
system.
