Straight answers about sensing, privacy and what it takes to install.

ALLIE fixtures use mmWave radar, acoustic and environmental sensors built into standard switches, outlets and vents. Radar resolves motion, posture and position in the room; acoustic sensing listens for events, not conversations. On-device AI interprets those signals in the room, so the system recognizes a fall or distress the moment it happens, with no video and no wearable.

Sensor data is processed locally inside the fixture. What leaves the room are events and summaries such as 'room occupied' or 'fall detected in bathroom at 02:14', not raw signals, images or recordings. Operators control retention and who can see what.

Yes. There is no camera in any ALLIE fixture and no audio is recorded, so guests keep their privacy while the property gains room-level occupancy: HVAC and lighting set back when the room is empty, and housekeeping knows a room is occupied before anyone knocks. In hotels ALLIE is deployed for occupancy, not for monitoring guests. Guest-facing notices and opt-out workflows are part of the deployment plan.

Occupancy sensing tells the building which rooms are actually in use. ALLIE relaxes heating and cooling in empty rooms and restores comfort when people return, turns off lighting and idle plug loads nobody is using, and can shed non-critical loads to stretch backup power. Because it senses people rather than keycards or schedules, it keeps working when a guest leaves a card in the slot or a resident's day changes.

ALLIE delivers real-time alerts with room-level location to the people you designate and escalates on configurable timers when no one responds. It is designed to work alongside your existing nurse-call, security and building-management workflows rather than replace them.

Radar can observe physiological motion such as breathing and heart-rate patterns as well as movement and gait, all without contact. These signals are used for presence, activity and distress detection; ALLIE is not a medical device and does not diagnose conditions.

ALLIE fixtures replace standard switches, outlets and vents in the same boxes and openings. There is no hub to install in the room, no renovation and no cameras to mount. Typical installs are done room by room during regular maintenance windows or renovation cycles.
