We recognize
that selecting a surveillance DVR recorder can be confusing. Here's
some info which could be useful.
DVR
REALITY CHECK / QUALITY DIFFERENCES:
We
understand that there are tons of CCTV and security video recording
options available from which to choose. We shop and test the technology
a LOT more than any average consumer and please believe it can
be just as frustrating, even at the OEM manufacturing level!
*Please
read our "Dirty Little Secrets about PC recording cards"
at the bottom of this page before closing and consult our wireless
FAQ section for much more specific questions and detailed answers.
Over
the last many years, we learned that 99% of our video surveillance
and security customers BASICALLY WANT THE SAME THING: high quality
video that is reliable for their given application. And it has
always been our primary aim to SATISFY those customers by providing
it.
Digital
video recording has entered the "mainstream" and brought
with it a FLOOD of various technologies to the marketplace. How
do you know who or what you can trust amidst all the hype? Go
to experienced video experts who tried it FOR YOU first... qualified
people who 'know better' when they see strengths and weaknesses
of a particular system or device.
Eyespyvideo.com
is a company which believes in supplying our clients with the
VERY BEST quality equipment for practical use in 'the real world'
where the truth doesn't always jive with the ad copy. We are also
one the few distributors who won't hide the practical limitations,
or what a recorder (or camera or transmitter, etc.) will NOT do.
We only choose RELIABLE models and test them before release, to
be sure it won't be your headache... and then later ours as well.
Don't
be BLINDED by buzzwords or fooled into putting too much emphasis
on NUMBERS on PAPER. In the electronics industry (including and
maybe especially video), those numbers often don't give an accurate
representation of what end-quality performance and satisfaction
the user will experience. These numbers almost NEVER give any
consideration to the level of engineering and manufacturing of
a particular device.
The
MOST often overlooked but MOST IMPORTANT DVR aspects we consider
for you:
RELIABILITY
of OS (operating system) and quality-level of processor components
used to build device are MORE than just important- since this
is the fundamental ROOT of the video recording you are trying
to accomplish. How important? Have you ever heard the term 'crash'?!
Read more in the FAQ section and in the "dirty little secrets"
segment below to see why we don't even fool with PC-based OS systems.
TRUE
SPEED of recording and playback is not only judged in numeric
"frames per second" (FPS), but in realistic human eye
tests by experts and novices alike. The often-touted display or
'refresh' speed rate doesn't matter much, since many junk DVRs
can allow user to view all cameras in 'real time' with no visual
drag. In fact, there are plenty of 16 channel recorders which
'view' at 480 fps shared but RECORD at only 30 fps shared- that's
less than 2 frames per second per channel! That's about 28 FEWER
FRAMES PER SECOND than our realtime 16 unit, with the overwhelming
deficit seen on each and every channel. **BUT, every once in LONG
while, the specification numbers error in the user's favor. Our
#DVR-N4, for example- easily outperforms its underwhelming speed
spec and provides near-to-real time viewing of all recorded cameras.
The #DVR-N16 literally BLOWS AWAY its own specs about 5 times
over! You never know until you KNOW.
TRUE
QUALITY of recorded video on playback of individual channels is
the KEY (besides speed) to good video archiving and playback.
Just as any ten different cameras which 'spec' at 380 lines will
likely EACH provide a different visible image onto a screen, a
DVR 'lines of resolution' specification is an indicator- but not
an accurate judge of comparative quality. Specifications are just
numbers and there are 'good' and 'bad' 320 x 240 and 720 x 480
recorders. Each will provide its own level of end-user quality
and satisfaction. *It NEEDS to be mentioned that so many shameful
or ignorant sellers out there are listing recorders at "480
lines of resolution" ability when it USUALLY HAS NOTHING
TO DO with the ACTUAL RECORDING resolution. The higher number
refers ONLY to the display lines available to a single camera
in full frame VIEWING only (kind of like the display vs. record
issue mentioned above). Many devices ALSO have variable speed/
variable quality so that the highest resolution setting might
only be attained if the speed of recording is slowed way down!
Many list ONLY the 'up to' spec for speed and quality of resolution
and, in the case of DVRs, that can be a BIG problem. We actually
do carry realtime 480 lines PER CHANNEL digital recorders (as
well as some really good 240 line units) and actually do know
the differences.
MOTION
DETECTION QUALITY / ability and ease of adjustment or use are
VERY IMPORTANT if motion recording is intended or desired. In
fact, MOST security dvr users wish to record actual activity ONLY
and set their systems up for 'motion detect' recording to maximize
disk space, as well as minimize headaches scanning through unnecessary
video to pinpoint a given event. Many motion detection protocols
built into certain DVRs are OLD with non-adjustable sensitivity
and often are not sensitive enough for quick and reliable activation
of recording. Some are even downright crude and totally unacceptable
for realistic use in different lighting conditions.
USER-FRIENDLINESS
of features, setup and normal viewing and retrieval is the MOST
IMPORTANT feature of all to many of our customers. Many DVR systems
(even standalone box units) can be difficult to use and set up.
This is bad enough to begin with, but these devices are often
left unattended for weeks or months where the user may be forced
to continually re-learn difficult controls just to access certain
video. Almost every DVR we carry is ACTUALLY EASY to use and that
is a crucial element to our final decision in which products we
will carry. If it doesn't have EASE of use, it better have something
else pretty unique or it's just not worth it. We never want our
customers to be disappointed by a product we tried to convince
them was great.
HARD
DRIVE type/ quality, speed and buffer of the media on which the
recorded video will be stored for later playback is one of the
MOST overlooked aspects. Ours are specially selected high-quality,
high-speed reliable drives from ONLY top manufacturers Western
Digital®, Seagate® and Maxtor®. All 4-16 camera DVR
recorders are outfitted with 7200 RPM drives with 8MB buffer cache
memory. 'Theirs' may well be slower 5400 RPM drives with 2MB or
likely even no buffer at all. Is your video- which COULD become
invaluable evidence- really worth taking the chance on?
INCLUDED
ACCESSORIES necessary to use device successfully right out of
box? We go that 'extra step' and spend even a few more bucks for
you by including plug adapters, cabling and often many more items
that don't come with the unit from the factory.
The
'dirty little secrets' about PC recording DVR cards
To
begin with, most (but certainly not all) of the PCI slot digital
video recording cards you see out there are made of JUNK components
and come with unreliable software filled with quirky little conflicts
which may 'crash' regularly.... resulting in the DREADED LOST
VIDEO (and of course "Murphy" will always make certain
it's just when you actually NEEDED it).
These
cards seem to be advertised as a quick, cheap and easy way you
can get 'double-duty' from your home or office PC, by also turning
it into a reliable multi-camera security recorder 'on the side'.....
which is kind of like telling a person spinning 10 plates to do
the laundry while they're at it.
Too
many DVR card purchases have evolved into a 'build your own computer
kit' when user finds out they don't have some or all of the required
or recommended hardware in their PC. This is the point at which
most rational people realize they made a MAJOR MISTAKE and that
all they REALLY WANTED to do was plug in 4-16 cameras and be able
to easily view and access their video in a fast, reliable format.
Too late!
Especially
for multiple camera projects, even a good computer is virtually
rendered unusable for any other purpose after becoming a dedicated
video recorder. The processing requirements of bandwidth data
are GREAT for just one camera.... but for multiple cameras- it
is really HEAVY. Unfortunately, most PC-based DVR recorders you'll
find out there have been downgraded on the stuff you can't see-
like the processor quality and speed, motherboard, video card,
memory and more. You could easily spend OVER $1000 obtaining just
quality computer hardware components themselves, NOT including
the card itself- or even the outer case, keyboard or monitor.
And, even after all that, you may still find that you built a
'killer system' around a DOG of a recording card- or that the
software itself is unreliable for your situation.
PC
computers meet a wide variety of needs in a wide range of applications-
but that may actually be DRAWBACK when setting up as a recorder.
So many 'settings' already installed in your computer (from software
programs you use, etc.) may actually result as system CONFLICTS
when in the presence of the new recording software.
Our
BEST RECOMMENDATION is to use your PCs for networking to your
DVR ONLY. Use a high quality non-PC EMBEDDED OS standalone DVR
for actually recording and storing your video!
FINAL
SECRET about these so-called miracle cards. If you have problems
setting up your DVR card system with your PC, don't 'hold your
breath' for any good technical help either. Be prepared to be
told to "examine your computer's user manual" or be
sent to a web address to download something which may or may not
have anything to do with YOUR trouble! YOU HAVE BEEN WARNED!!!
