DVR cards Description
Product Name DVR cards Brand Kingnow Country of Origin China Model HB15XX series Product Description DS-4000HC compression card is a professional digital security product, which adopts the most advanced H.264 video compression algorithm and OggVorbis audio compression technology. Compared with DS-400xM and DS-400xH card, it can capture and compress video in realtime into H.264 streams, CBR (Constant Bit Rate) or VBR (Variable Bit Rate), which can realize up to 16 channels CIF resolution real-time encoding (DS-4016HC), at the same time the configuration manner is more flexible, can switch between 4 channels CIF and 1 channel 4CIF encoding. DS-4000HC?s SDK is compatible with DS-400xM and DS-400xH?s .This makes development faster and easier. DS-4000HC card uses fully optimized algorithm based on DSP technology to realize video & audio real-time coding, active video & audio preview and motion detection, etc. Video image is directly transmitted from card 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 and will not affect each other. DS-4000HC compression card supports 2000/XP operating system at present. HIKVISION provides demonstration application with its source code, the whole SDK development package including board SDK software, player SDK, network SDK, media Player plugging , etc and also provides technical support and good after- sale service. video?
