Don't Look Up.
Wearable drone detection system
A compact, helmet-mounted drone detection system providing real-time early warning against aerial threats. Detects and classifies hundreds of commercial and tactical drone types at distances exceeding 1 km, with an instant audio alert delivered directly to the operator's helmet.
Silent watch.
Instant warning.
DLU is built for operators who cannot afford to look away. Helmet-mounted and entirely passive, it continuously scans the RF spectrum used by commercial and tactical drones, evaluates threat confidence in real time, and delivers an audio alert through an in-helmet speaker — no screen, no glance, no emissions.
At 15 grams, it disappears into the kit. In use, it becomes the sixth sense that keeps the head down and the mission moving.
DLU Module · Helmet-Mounted
Engineered for
the helmet.
100+ Drone Types
Classifies commercial and tactical UAS across the full RF signature library.
> 1 km Range
Horizontal and vertical detection out to 1 km, with 360° coverage.
Helmet Audio Alert
Direct audio into comms — zero-look, zero-fumble warning delivery.
Passive RF
No emissions. Undetectable by adversaries, safe in EMCON-strict environments.
Ultra-Lightweight
15 g total sensor mass — imperceptible on an already-loaded helmet.
8-Hour Runtime
Runs on standard-issue battery packs for a full operational shift.
FOTA Updates
Signature library and firmware update over-the-air — no tear-down.
Velcro Mount
Attaches in seconds to any standard combat helmet. No tools required.
Two systems.
One mission.

- Thermal imaging for visual ID
- Detects RF-silent fiber-optic drones
- Bearing lock on detected threats
- Day / night operation
Live Thermal · Drone Detected
From RF to
alert in real time.
DLU continuously scans the RF bands used by commercial and tactical drones. On contact, the signal is classified, threat confidence evaluated, and an alert routed to the operator's helmet audio — all while the system remains fully passive, with zero RF emissions.
