AI Presence Detection · No Camera Required

See through
any wall.
Save any life.

Halo uses existing WiFi signals to detect human presence, vital signs, falls, and threats — through walls, in total darkness, with zero cameras. Deployed in minutes by first responders, safety teams, and care facilities.

Product Line

One sensor.
Three missions.

Every Halo product runs the same AI sensing core. Form factor and mission profile change to match your deployment.

Technology

Your WiFi is already
a sensor array.


STEP 01

WiFi fills the space

Every WiFi router continuously floods its environment with radio waves that pass through walls, furniture, and people — 24 hours a day, already in your building.

STEP 02

Bodies disturb the signal

Movement, breathing, and heartbeat scatter radio waves in measurable patterns. Halo sensors capture this across 56 frequency channels simultaneously — no camera, no contact.

STEP 03

Edge AI reads the pattern

A pretrained model running entirely on-device interprets the signal in real time — presence, breathing rate, fall events, threat posture — and fires alerts in under 2 seconds.

Deployments

Anywhere detection matters.
Cameras can't go.

01 // Elder Care

Fall Detection & Vital Monitoring

Continuous overnight monitoring for residents. No wearable compliance required. Alert fires in under 2 seconds — before staff would otherwise know.

02 // Public Safety

Overdose Detection

Bathroom stall monitoring for prolonged occupancy and absent breathing. Camera-free by law. Enables naloxone response before a fatality.

03 // Law Enforcement

Tactical Standoff Intel

Real-time occupant count, room-level positioning, and distress detection for active standoff situations — without breaching the structure.

04 // Fire & Rescue

Survivor Location

Locate breathing survivors through smoke and walls before crews enter. 30cm concrete penetration. Self-contained — works when building power is cut.

05 // Schools

Camera-Free Safety Zones

Locker rooms, bathrooms, and corridors — legally prohibited from cameras, but monitored for presence duration, fights, and after-hours intrusion.

06 // Home Monitoring

Aging Parent Protection

Peace of mind for adult children. One plug-in unit. Monthly subscription. Immediate alert on fall, prolonged inactivity, or vital sign anomaly.
