Vendors
The perimeter intrusion detection market is served by a mix of specialist PIDS manufacturers, security conglomerates with perimeter product lines, and camera/radar companies expanding into detection applications. Understanding who makes what — and where their strengths lie — is essential for specification and procurement. This guide maps the principal vendors by

Perimeter intrusion detection systems operate in a regulatory and standards environment that varies significantly by country, sector, and threat level. Understanding which standards apply — and what they require — is essential for specifying, procuring, and evaluating PIDS products and installations. This guide covers the principal standards and certification frameworks relevant to

Buried sensors provide covert perimeter detection — invisible to an intruder, unaffected by weather above ground, and immune to visual obstruction. The sensor is below the surface; the intruder walks, runs, or drives over it without knowing it is there. This makes buried detection the technology of choice for sites where

Video analytics has transformed perimeter security from a labour-intensive monitoring task to an automated detection capability. Where traditional CCTV relied on operators watching screens — an approach proven to degrade after 20 minutes of sustained attention — modern analytics systems detect, classify, and track intrusion events automatically, alerting operators only when a
Reference
Microwave barriers and active infrared beams are line-of-sight detection technologies that create an invisible detection curtain between a transmitter and a receiver. Anything passing through the curtain — a person, vehicle, or large animal — interrupts or distorts the signal and triggers an alarm. These technologies protect fence gaps, gate openings, rooftops,

Perimeter Intrusion Detection Systems (PIDS) rely on a range of sensor technologies to detect, locate, and classify threats along a facility's boundary. Each modality offers distinct advantages in detection range, environmental resilience, false alarm management, and cost per metre of coverage. This primer provides a practitioner-level overview of

Thermal cameras detect heat radiation emitted by people, vehicles, and animals, producing images that are independent of visible light. In perimeter security, this means detection capability that works in complete darkness, through smoke, and in conditions where visible-light cameras are ineffective. Combined with video analytics, thermal imaging has become a

Ground-based radar has become one of the fastest-growing segments of the perimeter detection market. Where fence sensors detect intrusions at the boundary, radar provides wide-area surveillance — detecting, tracking, and classifying targets across open ground at ranges from hundreds of metres to several kilometres. This guide covers the radar technologies used
Reference
Fence-mounted sensors are the most widely deployed category of perimeter intrusion detection technology. They convert mechanical disturbances — climbing, cutting, lifting, or impact on a fence — into electrical signals that are processed to distinguish intrusion events from environmental noise. This guide covers the principal sensor types, their operating principles, installation considerations,
