The calculation format is: Total Recording capacity =Used space per hour (MB/h)
(coverage rate of hard disk) × recording time (hour) ×channel numbers
For instance, one customer uses PAL cameras, set resolution to WD1, video quality to Lowest,
frame rate to 25 fps for enabling total 4 channels. He wants the unit to record continuously in
a month. Below is the calculation:
Total Recoding capacity =338 (mb/h) X 24(hours/day) X30(days) X4(channels)=
973440 (MB) ≈950 (GB)
Therefore, customers just install one SATA HDDs with 1TB, it can almost record for one
month.
