Introduction

This technical course is focused on the specialized area of **Perimeter Protection and Intrusion Detection Systems (PIDS)**, which form the first line of defense for any secured facility. Participants will gain in-depth knowledge on designing, selecting, and integrating various technologies, including fence-mounted sensors, buried detection cables, and outdoor radar/video analytics. The curriculum covers the critical process of balancing the need for reliable detection with minimizing costly false alarms caused by environmental factors. The goal is to ensure that the outer boundary of a facility is a robust, well-monitored layer that buys crucial time for a response force.

Objectives

Upon completion of this course, participants will be able to:

  • Conduct a site survey to select the optimal PIDS technology based on terrain, climate, and threat.
  • Design a multi-layered perimeter security system using deterrence, PIDS, and CCTV integration.
  • Specify, install, and configure various PIDS technologies (e.g., taut-wire, fiber-optic, microwave, radar).
  • Master techniques for tuning PIDS to minimize false alarms caused by weather, animals, or foliage.
  • Understand the integration of PIDS with the Security Management System (SMS) and response protocols.
  • Develop clear operational procedures for responding to perimeter intrusion alarms.
  • Calculate and justify the return on investment for advanced PIDS deployment.
  • Implement cyber security measures to protect PIDS network components and communications.
