Key Takeaways
- Irisys was a pioneer in thermal people counting, serving grocery and high-traffic retail for over 15 years
- The Vector 4D sensor was the flagship product with thermal-based counting and queue intelligence
- Privacy-first approach — thermal sensors with no cameras meant zero privacy concerns
- Irisys products have reached end-of-life and are no longer available for purchase
- Existing customers receive limited support — new buyers should evaluate alternatives like SenSource or Dor
Irisys (InfraRed Integrated Systems) was a well-known name in the people counting industry, particularly dominant in the grocery and high-traffic retail sectors. Their thermal sensors provided privacy-first foot traffic counting and queue intelligence without cameras, earning trust from major supermarket chains and retail operations across Europe and North America. However, Irisys has announced that their products have reached end-of-life and are no longer available for purchase. This review covers what made Irisys notable and what alternatives exist for current and prospective customers.
What Was Irisys?
Irisys specialized in thermal-based people counting sensors that detected body heat rather than visual images. This approach made their sensors inherently privacy-friendly — no cameras, no images, no video recordings. The company was part of the Fluke Corporation family and had built a strong reputation in the grocery sector, where their queue intelligence system helped supermarkets optimize checkout staffing based on real-time customer counts and wait times.
Irisys Technology & Vector 4D
The Irisys Vector 4D was the company's flagship sensor — a ceiling-mounted thermal device that could count bidirectional traffic and provide occupancy data in real time. The sensor used a thermal array to detect people based on body heat signatures, achieving approximately 95% accuracy in standard retail environments. The Vector 4D excelled in varied lighting conditions where camera-based systems might struggle, since thermal detection works equally well in bright, dim, or completely dark environments.
Irisys Queue Intelligence
Irisys's strongest differentiator was queue intelligence — the ability to monitor checkout lines in real time and predict when additional lanes needed to open. For grocery retailers processing thousands of customers per day, even small improvements in checkout efficiency translate to measurable revenue gains through reduced abandonment and improved customer satisfaction. The queue system provided real-time alerts to managers when wait times exceeded thresholds, along with historical data for staffing optimization.
End-of-Life Announcement
As of their latest announcement, Irisys products are no longer available for purchase. The company continues to provide limited support for existing customers only, but no new installations are being accepted. The Vector 4D sensor has been formally discontinued with an end-of-life notice published. For existing Irisys customers, technical support remains available through the partner portal and support@irisys.net, but the writing is on the wall: it's time to evaluate replacement solutions.

Irisys Pros and Cons
Irisys People Counting System (Legacy)
Pros
- Privacy-first thermal technology — no cameras or video ever
- Excellent performance in varied lighting conditions
- Strong queue intelligence for grocery and high-traffic checkout optimization
- Proven reliability with robust hardware designed for demanding environments
- Good API integration capabilities for connecting to existing retail systems
Cons
- Products discontinued — no longer available for new installations
- Limited to counting and queue analytics — no heatmapping, path analysis, or demographics
- Lower accuracy (~95%) compared to modern AI/video systems
- Required professional installation and on-premise infrastructure
- Existing support is limited and will likely sunset entirely
Final Verdict
Irisys was a respected pioneer in thermal people counting, particularly for grocery retail queue optimization. However, with products now discontinued, the practical recommendation is clear: current Irisys customers should begin evaluating replacement systems, and prospective buyers should look elsewhere. Dor offers the closest privacy-first thermal approach at a budget price point. SenSource provides stereo vision accuracy with occupancy management. FootfallCam offers the widest range of sensor options including thermal models.
