Basically, an intrusion detection system (IDS) is a device or software application that monitors network or system activities for malicious activities or policy violations and produces electronic reports to a management station. Fence or Perimeter Intrusion Detection Systems are systems which are implemented around or through the borders of installations/facilities to monitor and detect any kind of intrusion within the perimeter of the protected installations/facilities. FIDS-PIDS detection logic may depend on different types of technologies or a combination of all technologies such as vibration, magnetic, vibration, movement. FIDS-PIDS is vital component of a security platform. It can be supported by PA/GA, CCTV, BIDS etc. systems in order to have highest security level of protection. In case a need of different detection parameters, the perimeter can be segmented into sub-zones so that each sub-zone can be allocated its own detection parameters .
