  • Q10: How to calculate video storage capacity of HDD?2020-11-16
  • 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
