Camera-Free Occupancy Sensing for Buildings

Blutech uses thermal sensing and mmWave sensor fusion to understand presence, space use and project-defined activity events without conventional camera imagery. Connect useful occupancy signals to facilities, HVAC and privacy-sensitive safety workflows.

Presence and space-use monitoring

HeatMap Pro uses a 16×12 thermal array; HeatMap Fusion combines thermal sensing with mmWave radar. Select the device for the room geometry, required event types and integration rather than treating every sensor as an interchangeable people counter.

Sensitive-space safety events

Long-stay, no-motion and project-defined incident events can support agreed staff checks, local alerts and dashboard notification. Hospital and airport case studies describe privacy-sensitive deployments; event performance and response thresholds need site validation.

Occupancy data for HVAC and operations

Three Garden Road documents occupancy-led HVAC coordination. Core maps field signals to the agreed interfaces, while Halo provides status, history and floorplan context for authorised teams.

Three Garden Road

More than 1,000 connected devices support smart washrooms, water-leakage monitoring, indoor-air-quality visibility, occupancy-led HVAC coordination and ESG reporting.

Hospital Patient Safety

Non-camera accessible-toilet fall and incident detection deployed in hospital environments including Princess Margaret Hospital and Queen Mary Hospital.

What to measure in a pilot

Validate detection coverage, event quality and response workflow in the intended space. Where HVAC is involved, compare operating data against a documented baseline before claiming savings.

Questions about this solution

Do the sensors record faces or conventional video?

No. These solutions use thermal grids and, for HeatMap Fusion, mmWave radar instead of conventional camera imagery or facial recognition.

Is occupancy sensing the same as precise people counting or fall detection?

No. Presence, counting, long-stay and incident detection are different requirements. The model, placement, firmware and project validation determine which outputs are suitable; do not assume every sensor supports every event.
