Alarm Recording
Less disk space will be used if you set up your device to record only selected events, such
as only when an alarm is triggered. If the rate of triggered alarms is α%, then the hard
disk space needed in alarm recording (S
a
) will be calculated according to the formula:
S
a
= S

* α%
