Q
What is an IZON DVR?
A
An IZON DVR (Digital Video Recorder) is a PC device which
acts like a VCR in that it has the ability to record
and playback video image. IZON DVR takes the feed from
a camera and records it into a digital format on a storage
device which is most commonly the hard drive.

Q
Does the IZON DVR use the latest components?
A
We at IZON believe that it is important to have the complete
package of the latest components in order to receive optimum
performance. The absence of one aspect of a current generation
solution may "bottleneck" the system and in some
cases even hinder the performance instead of enhancing.
Additionally, the right combination of products needs to
be tweaked for optimal performance.

Q
Does learning how to operate an IZON DVR require knowledge
of PCs?
A
While knowledge of using a mouse and keyboard is helpful,
it is not required. Anyone can learn to operate and program
any of the IZON DVR functions, our software was designed
with user-friendly Graphic User Interface for ease of use.
Top
Q
What should I do if there is new version of IZON DVR software
released?
A
Basically, we release newer version software periodically,
based on the changes on platforms and additional features.
We develop and test our software in up-to-date environment,
and there may be major revision that would prevent backward
compatibility if necessary. Therefore, it is recommended
to keep the original version of software that was purchased
with your IZON DVR. If the update is unavoidable, please
check with IZON Support to ensure your system meets requirements.
Top
Q
Are there any differences between IZON DVR software and
others?
A
Definitely. Software is just as important as the hardware.
Software that runs the principal functions of the IZON
DVR is driven by a database. Our architecture and design
of the database are crucial to our systems stability and
speed of which it processes the data. Other DVR systems
with poor database structures will slow down even the best
hardware and, in many cases, cause the DVR to crash.

Q
What is video compression?
A
When video is digitized by the IZON DVR, it can consume
as much as 165 million bits of data every second. Transmitting
this amount of data is not practical. To get around this
problem, a series of techniques - called codec (picture
and video compression/decompression techniques) - have
been derived to reduce this high bit rate. Their ability
to perform this task is quantified by the compression ratio.
The simple fact is, the higher the compression ratio, the
smaller is the bandwidth consumption. However, there is
a price to pay for this compression. Because increasing
compression causes an increasing degradation of the image.
Therefore, there is a balancing act of trying to achieve
the desired image quality along with speed.
Top
Q
What is the frame rate?
A
The frame rate is a number of images that are being displayed
or recorded over a specific period of time. Typically,
frames per second or "fps" is the specification
most often used. Keep in mind that frame rate record and
frame rate display are two different items.

PORT Below ports are set as default and can be changed
at "Start.exe"
3000 Image Transmission
3001 Pan Tilt and Control Command Transmission
3003 Setting Information Transmission

Q
What is a dynamic IP address?
A
When the internet was first conceived, the architects didn't
foresee the need for an unlimited number of IP addresses.
Consequently, there are not enough IP numbers to go around.
To get around that problem, many internet service providers
use dynamic IP addresses. Dynamic IP addresses are addresses
that are temporarily assigned to your computer from a pool
for an internet session or some other specified time. As
soon as the session or period is complete the number is
returned to the pool for use by another customer. Even
if the user reconnects immediately, the odds are they will
not be assigned the same IP address from the pool. You
can locate your IP address by typing in checkip.dyndns.org
in your browser.
Top
Q
What is a static IP address?
A
A static IP is a number that is assigned to a computer
by an Internet Service Provider (such as SBC, Verizon,
Comcast, etc.) to be its permanent address on the internet.
Computers use IP addresses to locate and talk to each other
on the internet, much the same way people use phone numbers
to locate and talk to one another on the telephone. Every
machine on the internet has a unique identifying number
which consists of four groups of number with no more than
3 digits in a group. A typical static IP address would
look like 216.211.253.155

Q
How many cameras can I plug into an IZON DVR?
A
Typically, you can plug anywhere from 1 to 32 cameras.
The cameras normally plug into BNC or RCA input on the
IZON DVR. Some boards come with a single video adapter
and uses a pigtail cable which has multiple adapters on
one end and a single connection on the other end.
Top
Q
Can I use my existing cameras with the IZON DVR?
A
Generally yes. Your existing cameras will work by plugging
into the back of the IZON DVR which replaces the VCR. Some
old CCTV cameras may require to have proper connector depending
on the connection type. If your cameras are not so current,
then you may want to investigate some of the newer cameras
which are higher in resolution and may have more features.
Typically, higher resolution cameras mean higher quality
image.

Q
What kind of cabling do I need to run from a surveillance
camera to the IZON DVR?
A
Standard coaxial cable such as the one which runs in your
home to connect with the cable company is highly recommended
(RG59U). You need to connect BNC connectors on the DVR
end and BNC or RCA connectors on the camera end depending
on the camera type. Try to keep cable length under 300ft
and avoid close proximity to fluorescent fixtures or other
electrical devices that may cause interference. For longer
distances, there are a variety of other solutions from
RG56U to fiber.

Q
What are the differences between RGB and YUV image signals?
A
RGB signaling refers to the method of dividing an image
signal to the fundamental three colors (Red, Green and
Blue) when processing the signal. It has the advantage
of good color division and conveyance, but the disadvantage
of requiring at least 3 color division data.
YUV signaling refers to the method of expressing an image
signal by the vertical and horizontal signal synchronization
(Y), and its color signals (U, V). Color division and conveyance
qualities are inferior compared to the RGB method, but
the YUV method can express more diverse colors using less
image data.
The choice of both methods are available on DVR. RGB image
will have clearer color but more 'blocks' on the image,
while with YUV image dividing between colors can be more
difficult but you will get a more smoother looking surface
from them.

Q
What are the backup devices supported by IZON?
A
Data backup devices include CD-RWs, DVD-RAMs, DVD-RWs,
DATs, etc., any device that Windows recognizes as a drive,
and you can also backup on a network drive.
The unit of the data is 1 minute, and can only be viewed
through the supplied Backup viewer. Data backup is also
possible on the Search program, where it can be saved in
AVI format, making it conveniently viewable through the
Windows Media Player (by enabling "View-Caption" from
the menu, you can also conform information data).

Q
What is the supported picture quality when recording on
an IZON DVR?
A
NTSC 352x240, 704x240, 704x480
PAL 352x288, 704x288, 704x576
Top
Q
When I view an IZON DVR remotely over the internet, how
come the pictures don't have the same quality or speed
as when I view it locally from the IZON DVR itself?
A
The answer is bandwidth. When you are viewing the IZON
DVR locally, you are transmitting right from the IZON DVR
to your monitor without having to send the image over a
network and worry about throughput. Throughput is the amount
of data transferred from one place to another in a specified
amount of time. The lower the throughput, the slower the
transmission.
Top
Q
If I connect remotely, will I view live video?
A
You are viewing live video as it happens, but the motion
and quality of the image are depending on your connection
speed to the location. Real-time/Real-motion video from
a remote location using the public internet or a dial-up
modem is virtually impossible if you want to simultaneously
view multiple camera image. There is simply too much data
to transmit across a narrow bandwidth.
Top
Q
When viewing video on some websites, how come they seem
to have no robotic motions and clear crisp pictures?
A
Because the video is "streamed" meaning it is
aggregated and then delivered on a delayed basis. There
is a difference between real-time and real-motion.
Top
Q
What are real-time images?
A
Real-time images are images that are being transmitted
as they happen, not to be confused with real-motion. Unfortunately,
the words real-time and real-motion are used synonymously
within the industry. Just because something is real-time
doesn't mean it's real-motion.
Top
Q
How do I view the IZON DVR remotely from my PC, laptop
or PDA?
A
IZON DVRs come with remote software which allows you to
view the cameras once you are connected to the IZON DVR
via a phone line modem, internet or LAN connection.
Top
Q
What are the precautions when recording sound?
The motherboards we use are equipped with high definition
audio controllers. As these new controllers automatically
adjust their settings. The only main precaution is that
you use an amplified microphone with the IZON DVR when
recording sound.
Top
Q
Is there special power requirements for the IZON DVR?
A
The IZON DVR is a security appliance that is designed to
run 24/7 nonstop. Therefore, it is strongly recommended
that you attach UPS to the IZON DVR in order to protect
the hardware against power spikes, reductions or outages.
Top
Q
Do surveillance cameras work in the dark?
A
It depends upon the camera. If the surveillance cameras
have Ex-view or infra-red (IR) capabilities, then they
can operate in a virtually zero light environment.
