The VID-04/08  (Full D1 / 4CIF - 704 x 480) compression cards are a professional digital security product, adapted to the most advanced H.264 AVC video compression algorithm and Ogg Vorbis audio compression technology. Ogg Vorbis audio compression technology makes the sound quality smoother, crisper and synchronized. The Newly designed PCB of the card is more compact, steady and compatible.

The VID-04/08 card uses a fully optimized algorithm based on DSP technology. This allows display of video and audio in real-time, an active video and audio preview and motion detection. Video images are directly transmitted from the card to the display frame buffer while the compression stream data is directly sent to the host's memory. The whole transmission process requires no intervention of the host computer's processor, greatly saving valuable resources. One Personal computer can support up to 64 channels of audio and video inputs. The parameters of each channel can be set independently and will not affect each other. Additionally, the card provides a characteristic profile in order to simplify development and testing procedures. Therefore meeting different application demands widens the market for the product. Incorporated with the DS-4002MD decoder card allows outputs to active video to analogue monitors, creating a virtual matrix solution.

The VID-04/08 compression cards support Windows NT/2000/XP.
