What your commander sees in real time.


  • 01

    Occupant count per room

    How many people are in each space. Updates continuously. Distinguishes moving from stationary subjects.

  • 02

    Room-level location tracking

    Which room each detected person is in, direction of movement, transition events between spaces.

  • 03

    Distress breathing detection

    Rapid, erratic, or absent breathing flagged with separate alert class. Hostage vital status in real time.

  • 04

    Panic motion signature

    Sudden chaotic movement pattern distinct from normal activity. Immediate alert to tactical channel.

Mission Profiles

Built for these situations.

01 // Barricaded Subject

Standoff Resolution

Know exactly which room the subject is in before any entry. Monitor breathing for signs of medical distress or surrender posture. Reduce negotiation timeline with real data.

02 // Hostage Situation

Hostage Vital Status

Confirm hostages are alive and their respiratory status in real time. Separate breathing signatures by room. Intelligence that changes tactical decision-making.

03 // Armed Intruder

Active Threat Location

Track a barricaded or moving threat through a structure without cameras or entry. Know where they are and where they're going before the first door opens.

04 // Welfare Check

No-Force Entry Intel

Confirm occupancy and vital signs before breaching. Locate an incapacitated person in a structure before forced entry — and know what room to go to first.

05 // Perimeter Security

Structure Clearance

Verify a structure is fully cleared after a sweep. Continuous monitoring during extended operations. Alert if anyone re-enters a cleared zone.

06 // Contraband Detection

Concealed Person Detection

Shipping containers, vehicles, confined spaces. A hidden person is breathing. Detect that breathing signature through metal and composite materials at close range.
