IP & Mega Pixel Security Cameras
If you're security surveillance system
requires the capture of high-resolution imagery, our high quality IP and mega
pixel security cameras may be well suited for your project.
Our IP and mega pixel security cameras
offer a significant leap forward in terms of surveillance video image
resolution. Take a look at the stacked image below. Note that the 1.3 mega pixel
image offers just shy of 400% more image real estate than 4 CIF and close to a
1600% improvement in image resolution over a standard CIF image.
A Note Of Caution: IP Surveillance Cameras Aren't For
Everyone
There is no question that IP and mega
pixel cameras offer the very best image resolution available for security
surveillance systems. The image quality is exceptional and
unparalleled.
There are a few really good reasons to buy an NVR and mega
pixel cameras, and there are a lot of reasons not to. While we would love to
sell you a NVR and IP/Mega Pixel Camera based security system, we want you to
educate you about the costs involved - both in terms of financial expense and in
terms of video surveillance systems requirements in a network
environment.
Mega pixel security cameras are more
expensive than analog security cameras in four main areas:
INITIAL COST - The
initial cost of a network based IP mega pixel security camera is significantly
higher than the initial cost of an analog security camera. A simple 1.0 mega
pixel "box or brick" camera for instance will run you north of $400.00 plus the
cost of the lens, housings, mounting brackets, etc. Compare that with a $125 to
$185.00 cost of today's 480 to 550 TVL analog surveillance cameras, and you
begin to see the problem. Sixteen 1.0 MP cameras would cost you at least
$6,400.00 plus lenses, etc. while a high end 550 TVL analog camera would only
set you back $2,960.00. That's more than twice as much...and you can buy a lot
of security system equipment for the difference.
STORAGE - Let's do some
simple math. 16 - 1.0 MP cameras, streaming at 30 FPS, will require just over 8
Terabytes of storage for one week. And That's if you are using an H.264 security
camera. If you're using a MPEG4 camera, the number is even worse - 12.5 TB!
Similarly, 16 - 550 TVL analog surveillance cameras at 30 FPS in 4CIF
resolution, will only require 2.5 TB of storage for the same week. Today, a TB
of DVR grade HDD storage space, runs about 180.00. Plus, you have to have the
DVR system that can accommodate that storage. At a minimum, you'll save well
over $800.00 just in storage space, by installing an analog surveillance
camera.
BANDWIDTH - This is the
worst culprit. If you plan to deploy 16 mega pixel security cameras on your
existing 10/100 or 100/1000 network, along with your existing data flow, plan on
a systemic network failure. You will shut your network down because it simply
cannot support that kind of bandwidth. Any more than 6 to 8 cameras must be on
their own network.
How much will that cost? It depends on
where you live but it can run from $600.00 up depending on labor costs,
materials cost, etc. Let's look again at some math: 16 Analog cameras, running
30 FPS at 4 CIF will need 16.48 Mbps of bandwidth only if it is streaming the
video out to a client user. If you are NOT streaming, then it will require ZERO
bandwidth. The 16 1.0 MP cameras, 30 FPS will REQUIRE 83.20 Mbps PLUS another
83.2 Mbps if you desire to stream it out to a client application. Think that
will cause a problem on your network? Just wait until your sales, accounting,
purchasing etc. staff can't process orders and paperwork, and we'll see how
happy you are with your mega pixel cameras.
Now, if that wasn't enough, consider
this; the ENT you purchase to make this all happen, is going to cost you even
more...and think about how much you'll pay in additional ISP costs to stream
that video.
POWER OVER ETHERNET or
POE - This is the much heralded solution to power and it is the devil
in disguise. Take a look at the average four port Ethernet injector - it has at
best, a 45 watt power supply. Now it's no secret that it takes about 15 watts to
run the router itself.....and about 10-12 watts for the average mega pixel
camera. See the problem? Simply not enough power. You will have to purchase high
end units, single units or only run two cameras on the expensive four port POE
injector to make it run properly...there goes your savings right down the
drain.
MORAL OF THE STORY -
mega pixel system are very nice, but they are also very expensive and you really
need to be fully educated before you make your buying decision.
That's what we are here for. We have
been doing this for a long time and we have designed systems from simple four
channel standalones to behemoth 200 TB NVRs. We're here to help you find the
proper solution for your particular need.
So give us a call today at
1-800-807-1271 and let one of our experienced engineers design a system specific
to your requirements and budget. |
