DVR compression cards are a professional
digital security product, adapted
to the most advanced H. 264 AVC
video compression algorithm and
OggVorbis audio compression technology.
OggVorbis audio compression technology
makes the sound quality smoother,
crisper and synchronized. The
Newly designed PCB of the card
is more compact, steady and compatible.
DVR board uses fully optimized
algorithm based on DSP technology
to implement video & audio
real-time coding, active video
& audio preview and motion
detection, etc. Video image is
directly transmitted from board
to display frame buffer and compressed
stream data is also directly sent
to host's memory. The whole transmit
doesn't need any intervention
of host computer processor, saving
resources of host computer's processor
greatly. One Personal computer
can support up to 64 channels
video and audio input, parameters
of each channel can be set independently
High Performance DSP H.264 (MPEG-4/Part
10) HARDWARE video compression
standard leads to high compression
ratio and good video quality.
OggVorbis audio compression standard,
with 16 kHZ sampling rate and
16 kbps output bit rate. Real-time
video and audio compression, no
frame lost. UP to 720 x 576 Recording
Resolution (CIF, 2CIF, D1 selectable).
4CIF (D1) preview resolution.
Set table I.B.P. frame sequence.
