What does PD stand for?
Probability of Detection
The three main characteristics of intrusion sensor performance are:
Probability of Detection, Nuisance Alarm Rate, and Vulnerability to Defeat
What does NAR stand for?
Nuisance Alarm Rate
____ is any alarm signal that is not caused by an adversary.
Nuisance Alarm Rate (NAR)
What does FAR stand for?
False Alarm Rate
A ____ occurs when the source of the alarm is unknown

- Bypass, The adversary goes around or beyond the sensor’s capabilities.
- Spoof, goes through the protected zone without an alarm being generated.
