The Detection Gap
Fibre-optic-guided and GPS-dark drones increasingly defeat radio-frequency detection. Cameras and radar struggle in the dark, in fog, and against small, low-flying platforms behind buildings or terrain. Monava NoVision™ closes this gap passively — listening for the one physical signature every drone still gives off.
How It Works
Passive 360° Monitoring
Zero active emissions — the sensor cannot be detected or targeted by anti-radiation countermeasures.
3D Geolocation
A single sensor delivers precise direction, elevation, and distance (X, Y, Z) for every detected source.
Non-Line-of-Sight Detection
Sound travels around buildings, terrain, and other obstacles that defeat cameras and radar.
AI-Powered Classification
Machine-learning models analyse acoustic spectrograms to identify specific drone types and filter out environmental noise, from traffic to industrial equipment.
All-Weather, Artic-Rated Reliability
Originally lengineered for avalanche and landslide monitoring in Nordic mountain terrain, the same sensor platform now delivers exceptional drone detection performance from sub-zero conditions to noisy urban corridors.
Structural Vibration Sensing
Detects anomalous vibration on fences, masts, bridges, and gates in real time — an added layer against physical intrusion.

From Detection to Response
Detections flow in real time into your existing command-and-control platform, with drone ID, distance, bearing, and classification. Because legal frameworks in liberal democracies tightly restrict kinetic and electronic countermeasures, Monava NoVision™ is built to pair with proportionate, non-kinetic responses — such as RF cyber-takeover, which safely guides a hostile drone to a predetermined landing zone rather than risking debris or collateral damage.
