Appendix B Calculate Recording Capacity
You can calculate the size of hard disk according to the saving time and NVR recording settings. The NVR uses fixed video bit
rate. The below are the details at different settings. The used space (MB/H) = Bitrate ч 8Ч 3600 ч 1024.
Resolution
Bit Rate
(kbps)
Used
Space(MB/h)
1080P
10M 4500
8M 3600
7M 3150
5M 2250
3M 1350
720P
6M 2700
4M 1800
2M 900
1M 450
512 225
The calculation format is: Total Recording capacity =Used space per hour (MB/h) (coverage rate of hard disk) ×
recording time (hour) × channel numbers
For instance, one customer set resolution to1080P, frame rate to 25fps, bitrate to 2048kbps Lowest for enabling total 4 channels.
He wants the unit to record continuously in a month. Below is the calculation:
Total Recoding capacity =900 (mb/h) X 24(hours/day) X30(days) X4 (channels)= 2592000 (MB)=2531.25(GB)
Therefore, customers just install two SATA HDDs with 1.5TB, it can almost record for one month.
