Answer:
A perimeter intrusion detection system (PIDS) is a device or sensor that detects the presence of an intruder attempting to breach the physical perimeter of a property, building, or other secured area.
the use of buried sensor for perimeter intrusion detection system, becomes very popular due to the advantage of been a discreet or even an invisible detection system and avoiding the need to build an above-the-ground fence to protect the perimeter due to costs or environmental reasons
Explanation:
<em>Description of 3 systems:</em>
Barrier-Mounted :Fence Intrusion Detection System
PIDS deployed on or in conjunction with a fence or other physical barrier (e.g. DAS cable or other motion sensors mounted on a fence).
Ground-based or Below-ground
:
PIDS deployed below ground (again a DAS cable can be used or pressure sensitive cable or electromagnetic field). These do not require a physical barrier.
Free-Standing
PIDS deployed above ground that do not need to be installed on or in conjunction with a physical barrier (e.g. bistatic microwave link).
Example of one PIDS system I have seen deployed in a familiar location is the ones at the prison which is a barrier mounted or some inairports that prevent small to cause harm to small animals.
To combine these components make up computing architecture.
You have to be carefull no bulling cuiberbulling people hurt there self for stuff like that
