Methods of Calculating HDD Capacity
1) Calculate the maximum capacity of the build-in hard disk.
*Timing Recording:
Step 1: Calculate the maximum capacity of the hard disk needed in selected channel per hour, suppose as Si
(MByte) (i is the channel number), and suppose the bit rate of the channel selected as D (Kbit/s). The formula
of calculation is:
Si =
（
D*3600
）
/
（
8*1024
）
= D * 0.439453125 MB
Step 2: Confirm the storage time length, suppose as T hours. The total maximum capacity of the hard disk
needed in selected channel for T hours, suppose as St is:
St = T * S1
Step 3: Confirm the total numbers of the channels, suppose as n. The total maximum capacity of the hard
disk needed, suppose as Sc is:
Sc = S1 + S2 + … + Sn
Alarm Recording:
Suppose the rate of alarming as
α%. The capacity of the hard disk needed in alarm recording supposed as
Sa is:
Sa = Sc *
α%
