i. It has sensors located on the wire mesh and at the base of the fence
ii. It can detect if someone attempts to cut or climb the fence
iii. It has a passive cable vibration sensor that sets off an alarm if an intrusion is detected
iv. It can cause many false alarms

A.
i

B.
i, ii

C.
All of them

D.
None of them

Explanation:
Perimeter Intrusion Detection and Assessment System (PIDAS) is a type
of fencing that has sensors located on the wire mesh and at the base of the fence.
It is used to detect if someone attempts to cut or climb the fence. It has a passive
cable vibration sensor that sets off an alarm if an intrusion is detected. PIDAS is
very sensitive and can cause many false alarms.
