H.264 encoder cards in HB-18 series are based on H.264/A_law compression standard and powerful DSP DM645 from TI. Video and audio can be kept entirely synchronous, video resolution supports CIF or Full D1 and frame ratio of video is adjustable continuously which can be up to 25frames/sec(PAL) or 30frames/sec(NTSC). Multiple boards can be installed on one PC and up to 32 channels encoding with max frame rate working together on one PC.

HB-18 series supports more than 64 channels real-time video preview. It provides full functions as required by DVR applications: such as encoding and playback, motion detection, OSD, video and audio preview, series ID number etc. All above functions do not need extra CPU resource of host PC.
