5.11.4. Record backup.
BACKUP tab allows copying records onto USB disks. The process of copying recordings has been
described in section 4.4
5.11.5. Reference of HDD Capacity Calculation
To choose capacity of HDD use the following formula :
Whole HDD Capacity = number of the channels × time in need (hour) × spent of HDD Capacity per
hour (MB/hour)
Similarly we can have the formula of recording time:
Note: 1GB=1000MB, not 1GiB=1024MiB, so HDD capacity shown in Base Configuration under
HDD Management less than real marked
File size per hour (CBR)
File size is more unpredictable when VBR style, please refer to the real size of recording file.
