Resolution
Format
NTSC
PAL
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 CIF, video quality to Lower, frame rate to 25
fps for enabling total 16 channels. He wants the unit to record continuously in a month. Below is the
calculation:
Total Recoding capacity =56.4 (mb/h) X 24(hours/day) X30(days) X16(channels)= 649728(MB)≈650(GB)
Therefore, customers just install two SATA HDDs with 320GB, it can almost record for one month.
