Dt = Di / T

Step 3: The bit rate of all the channels “Dc” is:

Dc = Dt *（8*1024）/ 3600 = Dt * 2.2756 （Kbit/s）

Alarm Recording

Step 1: Assume the alarming rate is α%, capacity of hard disk is “S”, the total numbers of the channel is “n”. The capacity

of hard disk needed per channel “Di” is:

Di = （S / n） * α%

Step 2: Assume the recording time length is T (hours). The capacity of hard disk needed per hour per channel “Dt” is:

Dt = Di / T

Step 3: The bit rate of all channels “Dc” is:

Dc = Dt *（8*1024）/ 3600 = Dt * 2.2756 （Kbit/s）
