Reference of HDD Capacity Calculation
The first time install DVR, please check if the HDD has installed.

There is no limitation of capacity of single HDD to DVR, please choose the HDD according to the saving time.

Computational formula of HDD Capacity:
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:
Recordingtime （ hour ）  
TotalHDDCapacity （M B ）
CapacityOccupationpe rHour（M B/hr） AmountofChannel
Note: 1GB=1000MB, not 1GiB=1024MiB, so HDD capacity shown in Base Configuration under HDD
