Minimum Hardware Requirement - How to calculate S value
Parameter denition:
M: parameter of resolution of camera.
Resolution 5 M 3 M 2 M 1 M VGA / D1 CIF
Value of M 37 27 22 14 3 1
N: FPS of Camera
S=M*N
For example: 16 channel system
a) 8 camera at 1 Megapixel resolution with 10FPS
b) 3 cameras at D1 resolution with 15FPS
c) 5 cameras at CIF resolution with 30FPS
a) M=14; N=10, S=14*10=140
b) M=3; N=15, S=3*15=45
c) M=1; N=30, S=1*30=30
S of All Cam.=(8*140)+(3*45)+(5*30)=1405
Therefore, the minimum hardware requirement is C level.
