The Recording capacity calculation is a function of the recording plan you configure.

The total space needed on the hard drive is a function of number of frames, number of events, video resolution(QCIF,CIF or FULL), and number of cameras involved.

One frame in QCIF is 4-5 KB on the disk.
One frame in CIF is 15-20 KB on the disk.
One frame in FULL is 30-31 Kb on the disk.

The size in influenced by the Quality and details of the image.
