The 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.
