Acoustic detection for drones radar can't see.

Watchpoint is a mesh of acoustic sensors that detects, classifies, and locates drones by sound. That includes fiber-optic FPVs, which carry no radio link and give radar nothing to find. The kit itself emits no RF and runs without infrastructure.

Problem

Counter-drone equipment was designed before fiber-optic FPVs existed.

A modern FPV, especially a fiber-optic variant, carries no electronic signature, cannot be jammed, and flies below radar coverage. Most of the equipment fielded against it was built for an older threat.

Radar cannot see fiber-optic FPVs

A fiber-optic FPV has no radio transmitter. It is small, flies low, and gives conventional radar nothing to lock onto. Any detection system built around electromagnetic emissions will miss it.

Jamming reveals your position

A jammer defeats radio-linked drones, but it also broadcasts your location to every direction-finding receiver in range. Transmitting in order to defend yourself makes you a target.

Most systems assume infrastructure you won't have

Many detection products need fixed power, an internet connection, GPS, or a central server. A forward position has none of that, and when the infrastructure drops out, the sensor stops working.

The System

A self-contained acoustic sensor mesh.

Every drone makes sound. Watchpoint nodes capture that signature, classify it on the device with a trained model, and triangulate the position across the mesh. The operator sees bearing and location on a map as it happens.

Acoustic AI Node

Each node runs a trained classifier on a custom microcontroller board. Detection happens on the device, with no cloud dependency and no single point of failure. Nodes are weatherproof, battery powered, and fit in a backpack.

Mesh Network

Nodes share detections over a self-forming mesh and compute time difference of arrival across the array. The network needs no internet or GPS and reroutes around lost nodes on its own.

Tactical Map

A web-based operator interface receives bearing and position data streamed from the sink node. The display shows the classification, the bearing from each node, and the estimated position on the map.

Kit Specifications

Four nodes, one backpack, ten minutes.

Built to be carried into a forward position and set up without a technician.

How It Works

From acoustic signature to map position in seconds.

01

Deploy Nodes

Place four sensor nodes around the area you want to cover. They organize themselves into a mesh without any configuration.

02

Acoustic Detection

Each node samples audio continuously. The onboard classifier picks drone signatures out of the noise floor in real time, including in loud environments.

03

Mesh Triangulation

Detection timestamps are synchronized across the mesh. The array computes a bearing from each node and estimates the target position from the time differences.

04

Operator Display

The sink node streams position and classification data to the tactical map. The operator watches the bearing, the estimated location, and the threat class update live.

Ukrainian battalions field-testing Phase 1

Three Ukrainian battalions are testing Phase 1 hardware in operational conditions. Their feedback goes straight into the next build.

v2 Roadmap
Autonomous Intercept

The next version intercepts what it finds.

When the v2 mesh localizes a target, it cues an interceptor FPV, computes an intercept vector, and guides the interceptor onto the target. Nobody has to aim it.

The operator approves the intercept and the system flies it, with no requirement for line of sight or manual piloting.

Autonomous Cueing

The mesh computes the intercept vector from acoustic position data and uplinks it to the interceptor FPV without aiming input from the operator.

Guided Intercept

The interceptor receives position updates as the target moves and corrects its flight path until terminal engagement.

No RF Homing Required

Target acquisition is entirely acoustic, so the target never needs to emit a signal and the interceptor needs no radar lock or RF seeker.

Human-on-the-Loop

Authorization to intercept stays with the operator. Everything below that decision runs automatically.

Build Status

What works today and what ships next.

We build and validate in parallel, and every subsystem goes from breadboard to field within weeks. The list on the right reflects the current state of the hardware and software.
