Smart building | People counting

Smart buildings run more efficiently with real visitor data. SensMax infrared sensors track IN/OUT movement, monitor floor occupancy and help optimize HVAC, cleaning and space usage without any wiring or cameras.

Timestamp feature

Visitors statistics provided per 5-minute time spans or in per-second statistics in a raw data format that helps to calculate certain occupancy trends for premises.

Wireless devices

Save time and money by installing wireless people counting sensors that don’t need any cabling works.

Directional count

Unidirectional and bidirectional people counting algorithms for your needs.

Ready to use reports

More than 20 statistical, analytical and financial reports sorted by hour, day, week, month, quarter and year.

Data export

People counting system supports data export raw data format for implementing statistics into 3rd party reporting applications.

Wireless Infrared People Counting System for Smart Buildings

The SensMax wireless infrared people counting system helps smart buildings track how many people enter and move through different floors, corridors, meeting rooms, and shared spaces. With accurate visitor and occupancy data, building managers can optimize cleaning schedules, adjust HVAC usage based on real demand, reduce energy waste, and maintain comfortable, safe environments for employees and visitors.

SensMax S1 and D3 infrared people counting sensors are battery-powered, cable-free, and easy to install at any doorway. They provide reliable IN/OUT movement data and deliver statistics to the SensMax reporting platform through SMX gateways. The system is fully GDPR-safe, making it ideal for offices, government buildings, universities, business centers, and public facilities.

Why Accurate Occupancy Data Matters in Smart Buildings

Modern buildings rely on detailed occupancy statistics to operate efficiently. With SensMax infrared people counting sensors, facility managers gain real-time insights into how each area is used, helping them reduce unnecessary energy consumption and improve maintenance schedules.

Optimize HVAC usage – adjust heating, cooling, and ventilation based on true occupancy.
Automate cleaning schedules – dispatch cleaning teams to areas with high traffic instead of fixed rotations.
Monitor floor-level occupancy – see how many people move between building zones and when peak hours occur.
Improve safety and compliance – ensure areas do not exceed recommended capacity.
Reduce operational costs – avoid over-lighting, over-heating, or over-cooling unused spaces.

How the Infrared People Counting System Works

Infrared sensors are mounted on both sides of a doorway at chest height. When someone passes through and breaks the infrared beam, the system registers a count. Bidirectional D3 models can determine if the person is entering or leaving. Real-time D3 TS versions update data every 5 minutes.

Data is delivered wirelessly to SensMax SMX gateways, which forward statistics to the cloud or a local server. Each sensor also stores up to 25 days of hourly backup data in case of temporary connectivity issues.

How infrared smart building people counting system works

Wireless infrared sensors send occupancy data to the gateway, which updates the reporting platform.

Key Advantages for Smart Buildings

Low installation effort – no wiring, no construction work, no ceiling access required.
Up to 2 years battery life – long-term autonomous operation with standard AA batteries.
Perfect for narrow areas – accurate counting in corridors, lobby doors, and small entrances.
100% privacy-safe – no filming, no images, fully GDPR compliant.
Backup memory – 25-day internal buffer ensures no data loss.
Scalable infrastructure – ideal for multi-floor office buildings or large campuses.

Typical Smart Building Applications

Floor-level occupancy monitoring for balancing building load.
Meeting room and conference area footfall for usage insights.
Shared space analytics such as cafeterias, lounges, and lobbies.
Restroom footfall tracking for optimized cleaning schedules.
Corridor or elevator area monitoring to analyze movement between zones.

System Components

SensMax S1 – unidirectional infrared people counting sensor.
SensMax D3 – bidirectional infrared counter for IN/OUT detection.
SensMax D3 TS – real-time IR counter with 5-minute updates.
SensMax SMX Gateways – LAN, Wi-Fi or long-range gateways for data delivery.

Reporting and Integration

Footfall and occupancy statistics are displayed in the SensMax reporting platform, which includes more than 20 ready-made analytical, operational, and administrative reports. Smart buildings can use the SensMax cloud or install the software locally. For integrations with BMS systems, APIs and MQTT are available for real-time data exchange.

Smart building occupancy monitoring reports

Reporting dashboards show occupancy per floor, peak hours, and area usage trends.

Business Impact

With detailed occupancy insights, facility managers can reduce heating and cooling costs, automate cleaning cycles based on real footfall, balance usage across building zones and improve visitor comfort. Accurate people counting data leads to smarter resource allocation, lower operational costs and more responsive building management.
