HDD Capacity Calculation

Calculate total capacity needed by each DVR according to video recording (video recording type and video file storage time).

1.According to formula (1), calculate storage capacity qi that is the capacity of each channel needed for each hour, unit Mbyte.

qi = di ÷ 8 × 3600 ÷1024

(1)

In the formula: di means the bit rate, unit Kbit/s

2.After video time requirement is confirmed, use Formula (2) to calculate the storage capacity mi , which is storage of each channel needed unit Mbyte.

mi = qi × hi × Di

(2)

In the formula:

 

hi means the recording time for each day (hour).

Di means the number of days for which the video should be kept.

3.According to formula (3), calculate the total capacity (accumulation)

qT that is needed for all channels in the DVR during scheduled video recording.

c

 

qT = mi

(3)

i=1

In the formula: c means total number of channels in one DVR

4.According to formula (4), calculate the total capacity (accumulation)

qT that is needed for all channels in DVR during alarm video recording (including motion detection).
