Embidio Sensor
Passive Acoustic Detection & Early-Warning System
Autonomous acoustic sensor module for real-time event detection — near-field and far-field alike. Embidio Sensor sees where cameras can't: in darkness, fog, behind sightline blockers, or wherever privacy rules limit video — complementing radar, RF, and optical sensors rather than replacing them. From drone detection and urban safety to environmental monitoring and wildlife conservation, it adapts to your use case. Detection range up to 500 m depending on source type and environment.

Acoustic Awareness for Complex Environments
Where Acoustic Intelligence Makes the Difference
Acoustic sensing opens new possibilities across security, environmental protection, and urban management:
Critical Infrastructure
Airports, energy plants, public buildings
Environmental Monitoring
Wildlife conservation, biodiversity, ecosystem health
Public Events
Mass gatherings, event security
Urban Safety
Noise mapping, vandalism prevention, city planning
Limitations of Existing Systems
Current detection technologies each have significant blind spots:
Radar
High costs, complex installation, struggles with small drones.
RF Scanners
Only detect drones with active radio signals. RF-silent drones remain invisible.
Optical Systems
Depend on visibility and lighting. Fail at night, in fog, or smoke.
The Solution: Acoustic Detection
100% Passive
No RF emissions, fully passive. Does not reveal its own position.
Sight-Independent
Works day and night, in fog, smoke, and poor visibility.
RF-Independent
Detects fiber-optic-controlled and autonomous drones without radio signals.
Complementary to existing systems: Embidio Sensor supplements radar, RF scanners, and optical sensors where they fail.
Hardware
The Embidio Sensor is built on divVoice's hardware platform for professional audio capture.
- Ruggedized design for outdoor deployment
- High-fidelity MEMS microphones
- Edge-AI capable processor
- Combines microphones with additional sensor types
- Ruggedized housing options up to IP65, selected per deployment
Key Capabilities
One deployment, comprehensive coverage: these detection classes run in parallel on the same sensor hardware and network, simultaneously watching for drones, vehicles, perimeter intrusions, acoustic anomalies, wildlife activity, and vandalism sounds.
Drone Detection
Real-time detection, classification, and tracking of UAVs: multirotor, fixed-wing, and hybrid platforms.
Vehicle Recognition
Acoustic identification of ground, air, and water vehicles through signature analysis.
Perimeter Monitoring
Continuous acoustic monitoring for intrusion detection and situational awareness.
Acoustic Event Detection
Detection and classification of acoustic events with direction-of-arrival estimation for source localization.
Bird & Wildlife Detection
Species identification through acoustic signature analysis, proven in DBU-funded field research. Enables long-term population monitoring and early warning of species decline — fully passive and non-invasive.
Vandalism & Graffiti Detection
Real-time detection of spray cans, impacts, glass breaks, and other vandalism sounds with automatic alerting to security services. Piloted in a German city underpass — on-device processing, no voice or speech recording.
Modular Sensor Fusion
Combines the microphone array with additional sensor types — for example gas, motion, radar, or Bluetooth — fused via the ConHive platform. Further sensor types are possible depending on the use case.
Concurrent by Design: The same hardware and network run every detection class at once, adapted to customer-specific tasks through targeted training — not a menu of single-purpose products.
