Which of the following is not a characteristic of an electrostatic intrusion detection system?
A.
It creates an electrostatic field and monitors for a capacitance change.
B.
It can be used as an intrusion detection system for large areas.
C.
It produces a balance between the electric capacitance and inductance of an object.
D.
It can detect if an intruder comes within a certain range of an object.
Explanation:
B: An electrostatic IDS creates an electrostatic field, which is just an electric field associated with static electric charges. The IDS creates a balanced electrostatic field between itself and the object being monitored. If an intruder comes within a certain range of the monitored object, there is capacitance change. The IDS can detect this change and sound an alarm.

靜電的IDS創建一個靜電場，這僅僅是靜態電荷相關聯的電場。 IDS的創建被監視本身和物體之間的平衡的靜電場。如果入侵者來在一定範圍內的監視對象內，有電容變化。該IDS可以檢測到這種變化，並發出報警聲。
