DVR (Digital Video Recorder) which will work best for your needs
depends on 2 factors
1) The # of cameras that you will need.
2) The Frames Per Second (FPS) and recording Resolution that you will need.
The Number Of Cameras That You Will Need
It is important to purchase a DVR system that will support the number of
cameras that you will need now and in the near future.
Resolution: How Clear is
For TV Television broadcast
specifications (which CCTV uses) the maximum resolution that can
be recored and stored on your hard drive is 704 x 480 (NTSC for
the United States) and 720 x 576 (PAL for Europe). This
resolution is known as
D1 resolution (704 x 480).
A high end Commercial grade DVR recorder is capable of
recording up to D1 resolution on all channels
(Gold or Platinum DVRs).
The Highest resolution available to record on CCTV DVR systems
is D1 resolution (704
x 480). Many
standalone dvr recorders are advertised that they can support
real time recording which is 30 frames per second, but if you
read the specification of the DVR, they are recording at CIF
resolution which is 352 x 240. ONLY our Platinum DVR can record
every single channel at full D1 704 x 480 @ 30fps on each
channel...for example, our 16ch Platinum DVR has a total record
rate of 480fps giving you 30fps per channel. 480 divided by 16
gives you 30fps total per channel.
Resolution - 704 x 480
Resolution - 352 x 240
176 x 120
The Frames Per Second (FPS)
As a benchmark, a television show is broadcasted at 30 FPS which provides
crisp clean motion.
In security systems a full 30 FPS is only necessary when you need to monitor
close activity like a cash register where cash will be counted or in casinos
where fast action is taking place. For example, a 4 camera GOLD system
with 30 fps would give you about 7 fps per camera which is more then adequate
for most security needs.
With all of our units, you will be able to set the frame rate per camera.
DVR cards are great if you have a spare computer that meets our System Specs
and if you are capable of installing the unit and software on your own. It can
save you money but will require time on your part to install and troubleshoot
The DVR complete factory built unit is simply a matter of plugging in the
cameras and turning the unit on. If you are short on time and computer
technical skills then the complete system is right for you.
You can view your cameras remotely either by connecting directly to the
system using a mobile phone or network device (IPad/IPod/Android
Tablet), or through the internet through your network via laptop

How do I chose the right card
for a particular system?
Geovision breaks their product line down by two things.
Channels: This is how many cameras can be
captured and recorded by the DVR card. Total frames per card divided by
the number of channels/cameras that are installed.
Frames Per Second: This is the total number
of frames per second that the card can capture.
Slow: 1-4 fps - Slower than Time Lapse Video
OK: 5-9 fps
- Time Lapse Video
Good: 10-15 fps - Good Motion Video
- Perfect for Business or Home
Better: 16-29 fps
- Near Full Motion Video
Best: 30 fps
- Full Motion Video - Casino/Government
Choose a card that has enough video inputs to cover
the maximum number of cameras you need to use. Computer/Cameras not
Example: The GV-1240 card can record a total of 240 fps. That means
that if you are use up to 8 cameras, then you will record 30 images per
second per camera. If you use 16 cameras, then you record at 15 fps each
(240 divided by 16).
