Overall capability option
The hard disk capability formula is:
Overall capability
（
M
）
=channel number*time
（
hour
）
*capability in an hour
（
M/hour
）
The recording time formula is:
Recording time(hour)=
The DVR introduces the MPEG4/H.264 compression technology. Its dynamic range is very large so the hard disk capability
calculation is based on the estimation values of each channel creating files in an hour.
Example
：
The video files in each channel need 200M capability in an hour. For 4 channels and one month(24hours a day) the needed hard
disk capability is: 4channel*30days*24hours*200M/hour=576G. So it will need one 500G hard disks.
