4D Thermal People Counting

A discrete, flexible & highly accurate 4D thermal sensor camera system for live counting & reporting of visitor numbers, building occupation and footfall.

4D Thermal People Counting

Thermal imaging people counters are the most accurate, easy and reliable way of collecting visitor data. Compared to typical IP camera people counting solutions; D-Tech thermal sensors offer higher accuracy, better performance in low/no light environments, low/no maintenance and better ongoing reliability.

We can design and install a tailored network of thermal people counter devices across multiple buildings and locations to count your visitor numbers and store that data on a cloud server for 24/7 retrieval.

With a data accuracy averaging between 95 - 98%, our thermal imaging people counters are the highest quality counter available. As they track a person's thermal heat signature, they function equally well in brightly lit environments or complete darkness.

Commonly specified in libraries, museums, art galleries, or retail and leisure destinations, the small, quiet, and unobtrusive thermal imaging counter can be configured in a variety of ways. Track, monitor, and anticipate footfall trends. Display live data showing a buildings occupancy numbers, detect adults vs children, or even identify staff members by the lanyards they are wearing.

  • Small, discrete ceiling mounted counters
  • Up to 99.5% count accuracy
  • Thermal (heat sensing) operates the same in light or dark environments
  • Dual sensors - Thermal and Optical
  • Indoor or outdoor weatherproof options
  • Link up to 8 counters for very wide zones
  • Counters can be viewed, managed, and adjusted remotely
  • Long service life
  • Award-winning technology
  • Connects with multiple counters to cover larger locations

Configuration options include

  • Standard zone counting
  • Live building occupancy (displayed on a screen)
  • Staff detection
  • Adult vs child height detection

Data from the Counter is stored on a cloud server and is capable of handling many individual thermal people counters across multiple locations.  Staff can access the data via a web browser so it is easy to view real-time footfall across multiple locations, making it a useful tool for library services with multiple library branches.

This system has been installed in many significant UK sites including TATE Gallery, TATE Modern, Saatchi Gallery, The Imperial War Museum, Tate Liverpool, Blackshots Leisure Centre, Cambridgeshire County Council, Thurrock Council, London Borough of Enfield, London Borough of Greenwich, Pitt Rivers Museum, Suffolk County Council, Wigan Leisure, and Cultural Trust & York Libraries.

D-Tech People Counting Software is a cloud based administration, data collection and reporting tool for a network of D-Tech thermal people counters.

It can be used to remotely configure, track, monitor and anticipate footfall trends.  Visitor activity is measured across a pre-determined set of criteria and can even be measured against the weather.  Data can also be used for CIPFA submissions.

Data is administered via a web-browser so it is easy to view real time footfall across multiple locations, making it a useful tool for services with multiple branches.

Features include;

  • Web browser based administration of counters and reporting
  • Supports up to 100x thermal people counter devices from up to 30x locations
  • Option to view real time data across multiple locations
  • Wide range of settings and collection options
  • Exportable data into Excel for use with graphs and pivot tables
  • Easily add more counters to an existing system

York Explore Library Learning Centre


D-Tech has installed its Enterprise, thermal imaging people counter at the the newly opened York Explore Library Learning Centre. The new space provides a welcoming and well-designed flexible location that brings together a modern city library, with a full and vibrant programme of learning.

The thermal imaging people counter transmits data directly to a webbrowser application and therefore offers a number of benefits over traditional beam technology including improved accuracy, higher performance and the option to view real time data across multiple locations. The counter software offers a wide range of settings and collection options to provide data linked to a number of circumstancial, environmental and demographic pre-set applications. The quality and depth of data means that the collation of data is streamlined, takes up less staff time than other people counting technology and library staff can use the data to understand footfall trends across time, location and even the weather!

Helen Whitehead, Performance and Projects Manager, City of York Council, Libraries & Heritage department, explains her team’s reasons for choosing the thermal imaging people counter over other types: “ We are always keen to keep abreast of new technology in order to keep improving our service to customers. The new Explore centre has opened with technology which the public can see for example, the latest self issue and wi-fi, and other technology which they don’t notice, like the thermal imaging people counter. Seen or unseen, it’s all about improving the service to our customers. We’re proud to be leading the way in terms of using the latest technology to deliver a modern service.”

The Explore centre is in a highly listed building and it was important that the people counter is unobtrusive in the listed setting. Small, compact and with easy fixing, the thermal imaging people counter sits discretely in the ceiling transmitting its data efficiently and quietly with no intrusion on the library setting or visitors.

Helen adds: “Since the new Explore centre opened a few weeks ago we’re getting far more visitors than before, and the new people counter is diligently counting them all!”.
