1. Acorel
Acorel has been building automatic people counting technology since 1989, when it delivered its first large-scale deployment for the city of Lyon's transport network. Today the company runs on a combination of high-precision sensors — infrared, 3D stereo, and computer vision — feeding into its VISION cloud analytics platform, and it's trusted by clients including Orange, EuroAirport, and SNCF, with technology installed across more than 10 countries.
What it does well:
- High counting accuracy — sensors deliver 98%+ accuracy, holding up in crowded or high-flow environments where simpler infrared systems tend to lose reliability.
- Broad environment coverage — the same sensor technology and software platform scales from single-entrance retail stores to full airport terminals, train stations, stadiums, and city-wide public spaces, rather than requiring a different vendor for each use case.
- Static and mobility deployments in one platform — Acorel covers both fixed installations (buildings, retail, museums) and onboard transit counting (buses, trams, trains), unified through its VISION data platform.
- API-ready and modular — integrates with ticketing systems, CRM, building management systems, and weather APIs, so counting data can trigger real operational responses rather than sitting in a standalone report.
- Predictive analytics, not just raw counts — the platform forecasts flow and occupancy trends rather than only reporting historical numbers, helping teams plan staffing and resources ahead of demand.
- Privacy by design — anonymous detection with no personal data collection, built for GDPR and CNIL compliance from the start.
Acorel's differentiator is breadth combined with depth of experience: over three decades of dedicated focus on people counting (rather than counting as a side feature of a broader security or retail platform), with sensor and software R&D done in-house.
2. V-Count
V-Count pairs 3D active stereo-vision sensors with its BoostBI analytics platform, claiming up to 99% counting accuracy along with anonymized demographic analysis (age/gender). It's a popular plug-and-play choice for mid-market retail chains, with a large global partner network of over 600 customers across 130+ countries handling installation and support.
3. FootfallCam
One of the longest-running vendors in the category, shipping people-counting hardware since 2002 and now serving a large base of retailers, mall operators, and transportation hubs. Its lineup spans dedicated people counters, IP cameras, and an AI analytics layer (the V9 platform), making it a practical one-stop option for retail-focused deployments that want hardware and software from a single vendor.
4. DILAX
A German provider with strong public-sector and transit credentials, DILAX ships visitor-counting sensors with ePrivacyseal certification — an externally verified privacy standard rather than just a vendor claim. Its hardware supports unusually high ceiling mounts, making it well suited to atriums, transit halls, and large open venues where standard sensors don't have the range.
5. Xovis
A Swiss specialist known for premium 3D stereo-vision sensors, Xovis is particularly strong in airport and transit deployments where multi-zone queue analytics matter as much as a simple entrance count. Its newer PF-Series sensor covers a significantly larger area per unit than earlier hardware, cutting the number of sensors — and installation cost — needed for large spaces.
6. Density / Ariadne (camera-free alternatives)
Not every organization wants a camera counting people, even anonymized ones. Density (LiDAR-based) and Ariadne (a "hybrid fusion" approach combining time-of-flight sensors at entrances with phone-signal sensing indoors) skip video capture entirely. That sidesteps some of the GDPR and EU AI Act conversations that camera-based systems have to navigate, at the cost of a shorter public track record than the longer-established incumbents.
How to choose
- Sensor technology: infrared is cheapest but least accurate in crowds; 3D stereo-vision (Acorel, V-Count, Xovis, FootfallCam) is the current industry standard for accuracy; LiDAR and phone-signal sensing (Density, Ariadne) avoid cameras entirely for organizations prioritizing a camera-free privacy story.
- Single-use case vs. platform: some vendors specialize narrowly (retail footfall, or airport queueing); others, like Acorel, run one platform across static buildings and mobile transit deployments, which simplifies vendor management for organizations operating across multiple environments.
- Accuracy claims: look for independently verified figures rather than headline percentages alone, and ask for a pilot period to validate accuracy against your specific space and traffic patterns.
- Integration depth: the real value of a people count comes from what it triggers — staffing decisions, HVAC adjustments, alerts. Prioritize an open API over a closed dashboard.
- Privacy and compliance: anonymous detection with no personally identifiable data should be a baseline requirement for any public-facing deployment in Europe, and increasingly relevant everywhere given tightening AI and biometric-data regulation.
Most vendors will run a pilot on a handful of sensors before a full rollout — a sensible step, since counting accuracy can vary meaningfully between a quiet weekday and a crowded peak period.
