| Description£º |
EM-4008HEI card is high end production of security market, It can capture and compress 352 * 288 dimension video picture at real-time using the advanced MPEG-4 video encode algorithm. It can provide picture quality near to DVD but only use it's half or even less data bandwidth.It adopts OggVorbis Audio compression algorithm and composite of Video&Audio are finished completely in the card. Video&Audio can be kept entirely synchronous and the frame rate of video is adjustable up to 25 F/S (PAL) or 30 F/S (NTSC) in succession.
EM-4008HEI compression card supports real-time video preview. Video image is directly transmitted from card to display frame buffer and compression stream data is also directly sent to host's memory. The whole procedure doesn't need any intervention of host computer CPU, saving resources of host processor greatly. It can realize many cards in one machine. One Personal computer can support up to 16 channels video and audio, parameters of each channel can be set individually and will not affect each other.
EM-4008HEI compression card at present supports WINDOWS NT/2000 and LINUX operation system, provides DEMO software with its source code, complete SDK development package which includes card software development package, player development package and network development package, to help developer to shorten development period
