Recording Capacity

The table below shows the approximate record capacity at different bit-rates for one mono channel on a 200GB hard disk. For 4 mono channels, divide the figures by four.

MPEG Data Rate Duration (kbit/sec) Days Hours 8  2427  6  ** 12  1618  4  16  1214  15  24  809  2  32  607  19  40  485  10  48  405  13  56  347  18  64  303  9  80  243  17  96  202  6  112  173  9  128  152  16  * 144  135  20  160  121  8  192  101  3  * 224  87  16  * 256  76  20  * 320  61  16  * 384  51  13  Note : Each pair of channels can be given a different bit-rate. * These Bit-Rates Are For Stereo Channels Only ** G.729 Bit-Rate.
