SA-4004H 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 compression 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 24 channels and audio input, parameters of each channel can be set independently and will not affect each other. In addition, this card provides characteristic profile in order to simplify developing and testing procedure, meet different application's demands and widen the market for the product. This card also can cooperate with SA-4004H decoder card to output active video to analog monitor, thus providing the whole solution for network digital security.

SA-4004H compression card supports WindowsNT/2000/XP and Linux operating system at present UA provides demonstration application with its source code , the whole SDK development package including board SDK software , player SDK , networks SDK , media Player plugging, ect and also provides technical support and good after-sale service .
