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
