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

(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.
