Features: 1 High stability----absolute Hardware compression and the professional embedded operating system RTOS, completely divorced from PC, can avoid virus infraction. 2 Top advanced arithmetic---- H.264 (MPEG4 Part 10) video compression. It's better than MJPEG, MPEG1, MPEG2 and wavelet in HDD occupation. Occupies less HDD space and more convenient for Network transmission. 3 Adopt G.722 compression format for audio 4 Each channel compresses the signal at real-time individually, the parameters[...]
