Audience intelligence for healthcare venues · Bangkok
Sees without
recording.
Alumbra reads the audience waiting at a lift, picks the message to fit, and proves who saw it — without storing a single frame.
How the instrument works
01 · LIGHT IN
A camera that keeps nothing
Frames live in memory for under 200 ms while the on-board processor counts people, groups, and attention. Then they are destroyed. No video is written, streamed, or kept — the software contains no image encoder, so saving a picture is not switched off. It is impossible.
02 · NUMBERS OUT
Aggregate readings only
Headcount, group composition, wide age bands, seconds of attention. When fewer than five people are present, age bands are suppressed entirely — a breakdown of two people would describe those two people.
03 · DECISION
The right message, in under a second
A family with a child steps up; the screen shows pediatric services before the lift arrives. Decisions happen on the device — no cloud, no profile, no memory of who was there.
What Alumbra refuses to do
No face recognition. No ethnicity, health, or income inference. No tracking between visits. Not as policy — as architecture. We publish this list because in a hospital, what a device refuses to do is the specification that matters.
The operator view
This is everything Alumbra sees.
Boxes, bands, counts. The operator page renders the device's entire worldview — there are no pixels behind it to reveal. When a hospital data-protection officer asks what the camera collects, we show them this screen and the event log. The answer fits on one page.
For private hospitals
Your lift lobbies already have an audience. Now they have numbers.
Hospitals promote their own service lines — checkup packages, family vaccination weeks, senior clinics — on screens nobody measures. Alumbra verifies every play: who waited, for how long, with how much attention, and it chooses the next message to fit the people actually standing there. Campaign approval references (DoHSS) are enforced as required metadata; a creative without its approval number does not play.
Every evening: verified plays, attention seconds, audience mix — k-anonymous, reproducible from the event log, in vocabulary compatible with standard out-of-home impression reporting. Nothing else was ever collected.
