Physical security IDSs can be used to detect intruders by employing electromechanical systems or volumetric systems. Which of the following provides the correct definition mapping?

i. Electromechanical systems work by detecting a change or break in a circuit.
ii. A photoelectric system detects the change in a light beam and thus can be used only in rooms with windows.
iii. A passive infrared system identifies the changes of magnetic waves in an area it is configured to monitor.
iv. An acoustical detection system uses embedded mesh installed on floors, walls, or ceilings.
v. Wave-pattern motion detectors differences in the amplitudes of the waves they monitor.
vi. A proximity detector emits a measurable magnetic field. The detector monitors this magnetic field, and an alarm sounds if the field is completed.
