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
