T Series video cards use the latest video process technology. Comparing to previous card, video quality is enhanced much and video resolution is enhaced by 10%. Resolution of D1 card is over 420 lines. At same time video data rate is dropped 10% in average. T Series video cards have less power consumption than previous cards.
T Series video cards have CIF, 2CIF and D1 types and support multi cards and types to work in a PC.
H.264 encoder cards in TM-1500 series are based on H.264/G.729 compression standard and powerful DSP PNX1500 from Philips. Video and audio can be kept entirely synchronous, video resolution supports CIF, Half D1 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-1500 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.
HB-1500 series supports Windows 2000/Windows XP and provides complete SDK development package, demo software in source code. SDK development package includes card software development package, player development package, network development package which fully meet DVR application requirements.
