False Alarms

[Omer]

Hi All,
I need to evaluate performance of an alarming fence systems. False
alarms are major issue.
I was wondering if there's a *definition* for false alarm. Is it # of
false alarms for somedistance in a given time? e.g. 5 false alarms per
mile per day.
Does that make sense?
Does anyone have better suggestion?
Thanks a lot in advance,
Omer.
