How it works
Motion in, the right message out
1 · Detect
A device watches for presence — via a USB webcam (software vision) or a simple PIR sensor.
2 · Trigger
The moment someone is near, it plays the scheduled spot — respecting cooldowns and play windows.
3 · Measure
Every play is reported in real time: motion vs scheduled, by device, by audience.
Devices
Two ways to sense your audience
AI vision devices
On-device computer vision counts who's nearby and plays the most relevant spot — privacy-first, with no images stored or uploaded. Perfect for audience-aware campaigns.
PIR motion devices
A low-cost passive-infrared sensor triggers playback on movement. Simple, reliable, and inexpensive to deploy at scale.

FAQ
Good questions
What hardware do I need?
Any Windows mini-PC with a speaker, plus a USB webcam for motion/vision. A one-line install connects it in about a minute.
Is the camera watching people?
No footage is stored or uploaded. Vision runs on the device and only produces anonymous counts — never identities or images.
How do advertisers get charged?
Campaigns are booked against ad space with transparent pricing; plays are tracked and reported.
Can I start without a device?
Yes — browse the marketplace and plan campaigns first. Hosting a device is a separate, optional step.
