H.264
H.264 uses a fully optimized algorithm based on Digital Signal Processor ( DSP ) technology. Display and recording of video and audio are in real-time and fully synchronized in both modes. Video feeds are directly transmitted from the video capture card to the display frame buffer and the compressed stream data is directly sent to the host's memory. The transmission process doesn't need any intervention from the host computer's CPU, greatly saving resources of the host computer's processor. The result is flawless images and sound regardless of how many channels are being monitored or reviewed.
