Passive RF drone detection

A drone can't fly
without broadcasting.
That's all we need.

PowerTech listens across RF, Wi-Fi, BLE and Remote ID to detect, locate and identify drones by their own signals — silently, legally, and down to the serial number. No radar. No jamming. Nothing that gives your position away.

The problem overhead

Small drones are the fastest-growing gap in physical security.

Cheap, quiet and hard to see, consumer drones cross fences and perimeters in seconds — and most sites never know they were there.

01

Contraband delivery

Drones drop phones, narcotics and weapons into secured yards, bypassing every ground checkpoint on the property.

02

Surveillance & recon

Cameras overhead map guard rotations, entry points and blind spots — reconnaissance for a later intrusion.

03

Disruption & airspace risk

An unauthorized drone near a runway, substation or crowd can halt operations or cause real harm in minutes.

How it works

Four radios. One fused picture of your airspace.

Drones and their controllers constantly announce themselves across the spectrum. PowerTech runs multiple software-defined receivers in parallel and correlates what they hear.

400 MHz – 6 GHz

RF spectrum

Wideband SDR sweeps flag the control and video links drones use, including bursty and hopping signals.

2.4 / 5 GHz

Wi-Fi monitor

Monitor-mode capture reads drone and controller MACs, OUIs and beacons — even as addresses rotate.

BLE 4/5

Bluetooth LE

Continuity and advertising traffic surface nearby devices and Remote ID broadcasts, including Coded PHY.

ASTM F3411

Remote ID

Decodes DJI DroneID and the Remote ID standard to pull operator location, position and serial number.

Signal fusion. Any one radio can be fooled. PowerTech cross-references detections across all four vectors, links rotating identifiers back to a single aircraft, and raises one confident alert instead of a wall of noise.

What it does

Detect, locate, identify — and prove it.

/01

Serial number recovery FIELD-PROVEN

Where a drone broadcasts Remote ID, PowerTech decodes it and captures the aircraft's serial number — a concrete, attributable identifier for your report.

/02

Live map & bearing

Detections plot on a real-time map with signal-strength distance estimates and directional bearing to help point you toward the source.

/03

Real-time alerting

Fused detections trigger instant dashboard and notification alerts the moment a drone enters your monitored airspace.

/04

Persistent logging

Every detection is time-stamped and stored — building a searchable history of drone activity over your site for pattern analysis and evidence.

/05

Distributed sensor nodes

Add satellite receivers to extend coverage across a large perimeter, all reporting into one unified operations dashboard.

/06

Web operations dashboard

Monitor the whole system from any browser on your network — no proprietary console or dedicated workstation required.

Why passive

Detection that never announces itself.

Radar and RF-jamming systems transmit — which means they can be detected, they can interfere with licensed spectrum, and active countermeasures are heavily restricted. PowerTech only listens.

Active systems

  • Emit energy — your detection footprint is itself detectable
  • Risk interfering with licensed and safety-critical spectrum
  • Jamming and takeover are legally restricted for most operators
  • Bulky, high-power, and costly to deploy at scale

PowerTech · Passive

  • Emits nothing — completely covert and undetectable in operation
  • Listen-only, so no spectrum interference and no FCC transmit concerns
  • Detection and identification only — none of the legal exposure of jamming
  • Compact, low-power sensors built on commodity SDR hardware
Deploy anywhere

The whole system fits in a case — and runs from your phone.

No towers. No trenching. No permits. PowerTech runs on compact hardware you can carry in, mount in a vehicle, or set down and reposition in minutes — and you watch the airspace from any device on your network.

Carry it in

A self-contained sensor kit — no fixed installation, cabling runs, or construction.

Power anywhere

Runs on a battery pack or vehicle power. Drop it exactly where you need eyes on the sky.

Deploy in minutes

Power on and it starts listening. Reposition between sites as the threat moves.

Monitor from any device

Secure remote access puts the live dashboard on your phone, tablet, or laptop — on-site or off.

Where it deploys

Built for the places drones aren't welcome.

Correctional facilities

Stop contraband drops before they land and attribute the aircraft behind them.

Critical infrastructure

Watch airspace over substations, water, refineries and data centers around the clock.

Airports & airfields

Get early warning of drones near approach paths and active runways.

Events & venues

Protect stadiums, rallies and gatherings from overhead surveillance and disruption.

Borders & perimeters

Monitor long, remote boundaries with distributed low-power sensor nodes.

Government & VIP sites

Add a quiet, always-on RF layer to secured campuses and protective details.
