Vaiden flagship · Early Warning

Passive acoustic
drone detection.

Strix detects drones purely by sound, including types that emit no RF and stay invisible to radar and radio scanners.

A mesh of solar-powered sensor nodes with on-device machine learning and a handheld field terminal. Fully offline, RF-silent, deployable in minutes.

The problem

Drones are a growing threat. Most sites have no warning.

Small drones can bypass fences, walls, and traditional security. Fiber-optic drones are immune to RF jamming and invisible to RF detectors. Existing detection systems are expensive and require infrastructure. Strix fills that gap with sound-based detection that works anywhere, using nothing but the sensor nodes and a terminal.

Key advantages

Built for environments without infrastructure

Cheap enough to lose

Built from off-the-shelf parts. Expendable by design: deploy, forget, replace. No expensive equipment at risk.

Fits in your hand

Palm-sized, weatherproof. Light enough to carry a dozen in a pack. No setup tools needed.

Solar powered

Runs indefinitely on a small solar panel. Weeks on battery alone. No cables, no charging logistics.

Hears what RF can't see

Acoustic detection works against autonomous, low-emission, and other drones that are invisible to RF-based detection.

No internet. No phone. No cloud.

The whole system runs offline over a long-range mesh. Alerts reach every node and terminal without any infrastructure.

Invisible while listening

Emits no RF during detection. Drones scanning for emissions cannot find it. Small enough to hide anywhere.

How it works

Detection that runs on the device

Microphones pick up the sound of drone motors. On-device machine learning separates that signature from wind, vehicles, and other noise in real time. When a drone is detected, the alert goes out across the mesh immediately.

Everything runs locally. No cloud required and no audio leaves the node. Connect one gateway to the internet for optional secure monitoring from anywhere (Starlink, cellular, or any uplink). Each unit is self-contained and field-replaceable.

Sensor Nodes

Solar-powered, autonomous acoustic sensors. Deploy around a perimeter. They listen, detect, and alert the mesh automatically.

Field Terminal

Handheld tactical display with live map of all nodes and alerts. Encrypted messaging and position-sharing between teams, independent of cellular or internet.

Use cases

Fixed sites and mobile coverage

Fixed area protection mesh layout
Fixed area protection: nodes surround a facility, perimeter, or event and forward alerts to a central monitoring point.
Mobile route protection layout
Mobile route coverage: nodes placed along a route forward alerts to a vehicle or portable terminal for early warning of drone activity ahead.
Nodes are placed close enough for acoustic coverage. The mesh radio links them across much longer distances, so a detection at one node reaches every device in the network immediately.

Border & perimeter security

Remote borders, outposts, facilities without infrastructure. Early warning without infrastructure or connectivity.

Critical infrastructure

Airports, power plants, prisons, government buildings. Perimeter drone detection that works independently of existing systems.

Events & private property

Outdoor festivals, sports venues, estates, farms. Affordable drone awareness without permanent installation.

Security & resilience

Designed for harsh and unsupervised conditions

For environments where devices may be exposed to interference, theft, or tampering.

Encrypted end to end

All data at rest and in transit is encrypted. Each device has a unique identity. Compromised units can be excluded from the mesh remotely.

Resilient by design

No single point of failure. Alerts route around jammed or destroyed nodes automatically. The system stays up as long as any path exists.

Fully air-gapped. No cloud, no cellular. If a device is lost or stolen, encrypted storage protects system data and compromised devices can be excluded from the network.
Status

Field-tested and built end-to-end in-house

Working prototypes have been validated in real-world conditions and refined through field testing. The full system, from signal processing to mesh networking to the dashboard, is designed and built in-house.

Drone deploying a Strix sensor node A delivery drone flies in carrying a Strix node in a claw, gently lowers it to the ground, releases it, and flies back. The deployed node then begins listening.
Rapid deployment: nodes can be placed by hand, vehicle, or drone, even in terrain too dangerous to reach on foot
