How to calculate video capacity
Calculation method: R is capacity of hardware needed, B is code rate, N is number of video channels and D is number of
days of video.
Size of video file per hour of single-path image: R
＝
B÷8÷1000×3600
Size of video file per day (24h) of N-path image: R
＝
B÷8÷1000×3600×24×N
Size of video file per D days of N-path image: R
＝
B÷8÷1000×3600×24×D×N
