What
make the Linux
powered DVRs
more reliable
and deliver a
better
security than
the counter
part Window
powered DVR?
A.
The key
advantage of a
Linux operating
system
for DVRs is that
Linux can be
customized,
which lets us
include only the
services
customers need.
Because the
Linux
source
code is open,
our engineers
can easily
go
into the code
and strip out
applications
you would more
typically see on
desktops,
such
as email,
spreadsheet
programs, web
browsers
and so on. They
can also add and
fine-tune
the services
needed on the
DVR
to
optimize system
performance.
There
are several
benefits
realized as a
result
of
this ability to
customize the
operating
system,
including
enhanced
reliability and security.
Q.
The reliability
and security
of a
digital video
surveillance
system is
critical to any
business/home
application. How
does a Linux
powered DVR help
to address these
issues?
A.
The
ability to
customize Linux
means that
the operating
system is not
constantly
executing
unnecessary
application
code. In
effect, the
reliability of
the system goes
up
because there
are simply fewer
things running
and therefore
less opportunity
for issues to
arise. Customization
impacts the
security of the
DVR
as well. By
removing
extraneous code,
you’re
also removing
potential
security vulnerabilities,
since most of
the active
computer
viruses out
there today have
been
designed to
attack server
and desktop
applications.
If those
applications are
still part
of your
operating
system, then
your DVR
is susceptible.
Q.
Why Linux-based
DVRs delivers
better
cost/performance
than Window
based DVRs.?
A.
Because
an optimized
Linux operating
system requires
less memory, or
RAM, to run DVR
applications
since it doesn’t
need to manage
the
desktop-type
services that
aren’t of
value in
a DVR. And
finally, because
Linux can be
copied,
distributed and
even downloaded
from
the Internet for
free, there are
no fees or
royalties to add
to your cost.
Q.
If I have a
Linux-based DVR,
do I need to
know Linux
operating system
to access and
manage the
Linux-based DVR?
A.
Not at all. In
the case of our
DVR systems,
although our
hardware runs on
a Linux
operating
system, we still
maintain Windows®
standards
on our client
side software.
All of our
remote
management
client software
is Windows
compatible,
and
you can
routinely
download
.avi video clips
and .jpg or
bmp
images from our
Linux DVRs
in
addition to
performing
remote configuration,
software
upgrades and
video management
from your
Windows-based
PCs.
