Passive RF Drone Detection

Know about drone activity before you see it. Earlier warning. More time to respond.

VigilRF is a passive RF drone detection system built to detect drone activity earlier and improve situational awareness, giving you more time to respond. Compact enough to be worn or vehicle mounted, affordable enough to deploy in numbers, and built to stand alone or serve as a redundancy layer alongside a full C-UAS program.

This live demo is driven by real drone detection data captured during field testing — not synthetic placeholder data.

By the time you see it, you're already behind.

Drones are small, fast, and cheap. Most have no systematic way to know a drone is present until someone physically sees it — often after it's already over a restricted area. VigilRF is a practical, rapidly deployable first layer of passive RF drone detection that closes the gap between no awareness and a full C-UAS program.

Active Before Takeoff
A drone's control link is live before it ever leaves the ground. Without RF awareness, the first sign of activity is when someone spots it overhead — and by then, you're already reacting.
Out of Sight
Below the tree line, behind buildings, in fog, or after dark — visual observation fails in the exact conditions where situational awareness matters most.
No Remote ID
FPV and homemade drones don't broadcast Remote ID at all. The drones most likely to cause real harm are the ones least likely to announce themselves.

What VigilRF does, step by step.

VigilRF runs a continuous passive RF monitoring process — from spectrum scanning through alert delivery — with no manual tuning required.

01

Scan

VigilRF continuously monitors the RF bands drones rely on, with Remote ID (RID) broadcasts as a second layer of detection. It listens entirely passively — capturing activity across these frequencies with no signal interference of any kind.

02

Analyze & Filter

Every captured signal is run against known drone RF profiles and judged on its pattern and spectral fingerprint — consumer, FPV, and homemade alike — with a pipeline tuned to suppress false positives and surface only what matters.

03

Surface & Log

When the system identifies likely drone activity, it generates a real-time alert on the live dashboard with relevant signal details. All activity — alerts, baselines, and session data — is logged automatically for after-action reporting.

What VigilRF delivers.

Earlier Warning

VigilRF can surface likely drone activity before visual confirmation, giving you more time to assess the situation and coordinate a response.

📡

Passive, Non-Disruptive Deployment

Entirely receive-only — no jamming, and no interference with any signal or device. Safe to deploy at public events, near airports, and at sensitive facilities without regulatory concern.

📊

Real-Time Dashboard Visibility

A live interface that shows alert status, signal activity, GPS position, and session data at a glance. Designed to be useful immediately — typical training time is under 30 minutes.

📋

Detection Logging & After-Action Documentation

Every detection is logged with a timestamp and supporting RF details. After monitoring, you receive a documented summary of what was observed — ready for review, incident reporting, or follow-up.

🔌

Open Integration

Alerts can feed directly into an existing C-UAS platform, command center software, or security stack through open API endpoints. VigilRF works as the detection layer that cues the rest of your system.

🎒

Small Enough to Go Anywhere

The full system runs from a compact, self-contained case — worn, mounted on a vehicle, staged at a temporary perimeter, or set up in minutes at an event. Deploy one unit standalone, or several across a site for wider coverage.

Where VigilRF fits today.

🎪

Public Safety & Events

Drone detection for stadiums, festivals, and venues where crowds and tight schedules make early warning matter.

🏭

Critical Infrastructure

Passive drone monitoring for airports, power plants, data centers, and other high-consequence sites.

🛡️

Corrections & Law Enforcement

Built for correctional facilities — detect contraband drops and document RF activity to support interdiction. Also a strong fit for local police operations and as a command center addition.

Maritime

Drone detection for ports, terminals, cruise ships, yachts, and operations on shore or at sea.

🏢

Commercial & Education

Drone monitoring for corporate campuses, healthcare facilities, schools, and other private operations.

🕴️

VIP & Security Operations

Discreet drone detection for executive protection, private estates, and protective security details.

Where VigilRF sits in a layered drone detection posture.

VigilRF works as a standalone first layer of drone detection — or as a redundancy layer inside a full C-UAS program.

Redundancy, in practice

If the primary system goes down mid-event, or is being transported between sites, VigilRF keeps passive detection running. And because each unit is self-contained, it doubles as an emergency backup: a power or network failure at the main system doesn't take drone awareness down with it.

Approach Best For Key Limitation What VigilRF Adds
Remote ID Receivers Tracking compliant drones that broadcast standard Remote ID signals Non-compliant, modified, or intentionally evasive drones — including FPV and homemade builds — do not broadcast. Threat actors are unlikely to announce themselves. Passive RF monitoring of drone control links is VigilRF's primary detection method — surfacing activity regardless of whether the drone broadcasts Remote ID. Remote ID is also used as a secondary detection layer when broadcast.
Cameras / Radar Visual confirmation and tracking once a drone is airborne and within range Cameras require line of sight and adequate lighting. Radar is expensive and prone to false positives from birds and clutter. Both require the drone to already be airborne and in sensor range. Drone control links are often active before the drone enters camera or radar range. Passive RF monitoring can provide earlier warning, giving you more time to direct a response.
Full C-UAS Suites Organizations with authority, budget, and personnel for active countermeasures such as jamming or kinetic response Six- to seven-figure cost. Federal authorization typically required. Long procurement cycles. Complex to operate and maintain. For organizations that cannot legally jam or defeat drones, VigilRF provides passive RF drone detection at a fraction of the cost. For those with full suites, it can serve as an additional RF sensor redundancy layer.

What VigilRF does — and what it does not.

What VigilRF Is

  • A passive, receive-only RF drone detection system
  • An early-warning layer built to detect drone activity before visual confirmation, giving you more time to respond
  • A privacy-conscious system that analyzes transmission characteristics, not communication content
  • A monitoring and documentation tool that logs detections, timestamps, and supporting RF data during deployment
  • A system that can be deployed on its own or with other C-UAS tools

What VigilRF Is Not

  • Not a jammer — it cannot disable, disrupt, or interfere with any drone or signal
  • Not built to identify the exact drone, the pilot, or an exact location
  • Not a replacement for visual confirmation — it is a cueing and situational awareness layer
