Main Stream and Storage Calculation:
It is best to set a constant Bitrate number to make
calculating recording storage space easier.
Calculate the storage space as described below for
each network camera recording for one hour.

Bitrate(kbps) / 8 x 60(sec.) x 60(min.) / 1000 / 1000
= The storage space for each hour(GB)

Example Question
：
If a camera is set at 1920x1080 (1080P)@ 10fps,
1000kbps as a Bitrate setting, how much space does a
storage device need to hold at least a month (30days)
of recording files?
Answer
：

1000(kbps) / 8 x 60 x 60 / 1000 / 1000 x 24(hrs) x
30(days) = 324(GB) / 1000 = 0.324(TB)
