How to calculate video storage capacity of HDD?

it's the theoretical value

The capacity of storage space should be calculated according to the days, bit rate and type


1. Bit rate: 2Mb (for example)


channel and time

Disk space   required

1 channel for 1   hour

2048Kb/8Byte*3600sec*=921600KB=900MB

1 channel for 1   day

900MB*24=21600MB≈21.09GB

1 channel for 30   days

21.09GB*30≈632.81GB

16 channel for   30days

632.81GB*16≈10125GB≈9.89TB


1. Bit rate: 4Mb (for example)


channel and time

Disk space   required

1 channel for 1   hour

4096Kb/8Byte*3600sec*=1843200KB=1800MB

1 channel for 1   day

1800MB*24=43200MB≈42.19GB

1 channel for 30   days

42.19GB*30≈1265.7GB

16 channel for   30days

1265.7GB*16≈20251.2GB≈19.78TB


2. Bit rate: 6Mb (for example)


channel and time

Disk space   required

1 channel for 1   hour

6144Kb/8Byte*3600sec*=921600KB=2700MB

1 channel for 1   day

2700MB*24=64800MB≈63.28GB

1 channel for 30   days

63.28GB*30≈1898.43GB

16 channel for 30days

1898.43GB*16≈30375GB≈29.66TB

Note: these tables are only for reference, and the actual values have redundant.
