How the SensMax S1 Works

The SensMax S1 IR people counter creates a narrow infrared beam across a passage.

1. A visitor crosses the entrance or corridor.
2. The beam is interrupted, and the counter records the event.
3. Counts are stored locally and uploaded at regular intervals via the SensMax SMX gateway to the reporting portal.

Because the device stores hourly statistics internally, short connectivity interruptions don’t mean lost data.

Why IR Instead Of Cameras

If you need reliable footfall data but don’t want the privacy overhead of video, an IR people counter is a straightforward choice.

• Privacy by design: no images, no faces, no personal data – just counts
• Simpler compliance: supports GDPR-compliant people counting without camera governance and retention policies
• Clear intent: purpose-built for entrances and corridors, not surveillance
• Lower operational friction: easier approvals for customer-facing and public environments

This is people counting without cameras – built for teams that want usable traffic metrics and a cleaner privacy posture.
Get privacy-safe footfall data – without video governance.

Installation & Privacy

Deployment is fast and cable-free:

• Mount the transmitter and receiver on opposite sides of the passage (tape or bracket)
• Align the infrared beam
• Insert AA batteries
• Pair with the SMX gateway

The result is privacy-safe people counting: the system is anonymous and designed for GDPR-compliant people counting because it does not capture video or identify individuals – only simple entry counts.
