Appendix
4.1 HDD Capacity Calculation
This chapter describes how to determine the size of the HDD you need when you install the NVR for
the first time.
The NVR adopts the MPEG4/H.264 compression technology and its dynamic range is large.
Therefore, the capacity of the HDD depends on the estimated size of files generated in each channel
every hour according to code streams.
Computational formula of HDD Capacity:
Whole HDD Capacity(M)= number of the channels * time in need (hour) * spent of HDD Capacity per
hour (MB/hour)
The meanings of parameters are as follows:
Number of the channels: Number of channels where you need to enable recording.
Time in need (hour): Time you need to record.
Spent of HDD Capacity per hour
Spent of HDD Capacity per hour(M/hour)=

BitRate
You can obtain the Bit Rate by using the following methods:
-In the GUI interface, choose Menu > Settings > Video , view the value of the Bit Rate.
-In the Web interface, choose Parameter Configuration > Local settings > Encoding Scheme,
view the value of the Bit Rate.
[Example]
If you select 4M for the bit rate and select four channels for recording and one week of recording is
needed, you can calculate the HDD capacity by using the following formula:
Recording time(hour) =7days*24 hours=168 hour
