Appendix B Calculate Recording Capacity
The recording capacity is mainly up to the record resolution, record stream, and
bitrate. Different image quality parameters decide different disk capacity
occupation in equal times. The bigger the record resolution, record stream, and
record bitrate is, the more disk capacity is taken up in equal times. The calculation
format of recording capacity is shown as below.
Recording Capacity(MB) = Bitrate(Kbps) ÷1024 ÷ 8 × 3600 × Recording hours per
day × Record Storage Days × channel numbers
3600 means record for an
hour(1TB=1024GB
，
1GB=1024MB
，
1MB=1024KB
，
1Byte=8bit).
