PIDS Market 2025 in Review: The Year AI Went to the Fence Line

The perimeter intrusion detection market in 2025 was shaped by three forces: the deployment of AI analytics across every sensor modality, the mainstreaming of fiber optic DAS, and the scale of government investment in border and critical infrastructure protection. Here is what defined the year.

AI Edge Analytics Became Universal

Every major product launch in 2025 featured AI classification as a headline capability. SightLogix shipped a next-generation SightSensor with a dedicated AI core trained on two million thermal images. Hikvision's DeepinViewX brought large-model AI inference to perimeter cameras. Verkada introduced AI fence-climbing detection as a software feature on its cloud-managed cameras. RBtec's RaySense brought machine learning to Israeli-made fence sensors. Axis Communications launched radar-video fusion with AI analytics at GSX.

The shift from traditional signal processing (frequency thresholds, zone-based rules) to machine learning classification is the most significant technology transition in perimeter detection since the move from analog to IP. The promise is simple: better nuisance alarm management. Whether the promise holds depends on training data quality, environmental diversity of the training set, and real-world performance across the infinite variety of site conditions that PIDS must handle.

The vendors who will win this transition are those with the most deployment data and the discipline to validate AI performance claims with field-measured false alarm rates — not laboratory benchmarks.

Fiber Optic DAS Reached Competitive Scale

Distributed Acoustic Sensing moved from specialist technology to competitive modality in 2025. Sintela launched Onyx and won Best New Product in Sydney. OPTEX/Fiber SenSys won the Intersec Dubai Award for EchoPoint. Gato Security pushed 120 km range claims into the Gulf and APAC markets.

The combination of standard-fiber compatibility, AI-based event classification, and falling interrogator costs has made DAS competitive with fence sensors and microwave barriers on perimeters exceeding 2–3 km. For very long perimeters — borders, pipelines, railways — DAS is now the default shortlist technology.

The fiber optic PIDS market is projected at $172 million (2024), growing to $244 million by 2032 at 5.6% CAGR. Expect consolidation: the technology is commoditising toward the software layer (classification algorithms and integration APIs), and smaller DAS vendors may become acquisition targets for larger security platform companies.

Government Investment Set Records

The US government committed over $8 billion to Smart Wall border detection contracts through DHS/CBP, with $4.5 billion in new awards announced in September alone. A separate $100 million+ contract for subsurface tunnel detection expanded the scope of border perimeter technology.

The Department of Defense deployed ground-based surveillance systems along the southwest border, and the Air Force awarded a $75.5 million contract to Persistent Systems for perimeter detection at ICBM bases across three states.

In the UK, Gallagher's E-PIDS achieved the latest CPNI standards, and the International Security Expo London co-located perimeter and counter-drone exhibitions — signalling that government procurement is driving the integration of terrestrial and aerial detection.

LiDAR Entered the Mainstream

The Senstar-Blickfeld acquisition (€10.4 million, announced December) was the year's clearest strategic signal. The largest pure-play PIDS vendor acquired a 3D LiDAR manufacturer, betting that volumetric point-cloud detection will become a standard modality alongside fence sensors and video analytics.

DFW Airport deployed LiDAR for perimeter monitoring. Ouster's Gemini platform integrated with Genetec for automated intrusion detection with 95% nuisance alarm reduction. OPTEX expanded REDSCAN Pro's market presence with a 100-metre detection range per sensor.

LiDAR's cost premium limits adoption at price-sensitive sites, but the technology trajectory — driven by automotive manufacturing scale — favours continued cost reduction. For specifiers, LiDAR should now be evaluated as a standard option, not an exotic alternative.

Vendor Consolidation Continued

Senstar's Blickfeld acquisition was the headline deal, but the consolidation trend extends across the market. RAFAEL-backed Senstar Technologies (through Aeronautics and Magal) now offers fence sensors, buried cable, video analytics, and 3D LiDAR under one corporate umbrella. Johnson Controls demonstrated a fully integrated intrusion-access-video platform at ISC West. Axis pushed single-vendor radar-camera-analytics stacks at GSX.

The long-tail of small, single-modality PIDS vendors faces an increasingly difficult competitive environment. Buyers want integrated platforms; regulators want supply chain transparency; and the AI analytics layer rewards scale (more data, better models). Specialist vendors will need to either integrate deeply with platform partners, target vertical niches too small for the conglomerates, or become acquisition targets themselves.

What to Watch in 2026

The Senstar-Blickfeld deal closes in Q1. NDAA Section 1260H enforcement begins in June. DHS tunnel detection contracts are expected in Q1. The counter-drone/PIDS convergence will produce its first integrated commercial products. And the AI analytics promises made at every trade show in 2025 will face their first full year of field validation.

PIDS Monitor will be tracking all of it.
