Where you position a people counting sensor determines the quality of every insight that follows. A misplaced sensor produces inaccurate visitor counts, distorted conversion rate data, and unreliable staffing models - not because the technology is wrong, but because the data collection point is. This guide covers the seven locations that matter most in a retail environment, the reasoning behind each, and the practical decisions that affect accuracy at every point.
VemCount achieves 98%+ people counting accuracy through a combination of AI-based employee exclusion, 3D stereoscopic sensor technology, and real-time data filtering. That accuracy is only realised when sensors are placed correctly. Our support teams handles placement, calibration, and height configuration during deployment - but understanding the logic behind placement helps store managers validate their setup and identify gaps. The seven locations below follow the same placement logic that underpins every people counting software for retail deployment Vemco has completed across 98+ countries.
The most common cause of inaccurate people counting data is not sensor failure - it is suboptimal placement. Footfall counting sensors placed too low miss individuals in bulky coats. Sensors positioned above wide entrances without overlapping coverage create dead zones at the edges. Sensors mounted facing direct sunlight produce interference patterns that reduce accuracy by 10-15% in some infrared-based systems.
VemCount leverages advanced people counting sensor technology rather than single-plane infrared beams, which significantly reduces sensitivity to lighting conditions and reduces the impact of positioning errors. Even so, placement decisions determine whether you are counting every visitor accurately or working from a dataset that systematically undercounts or double-counts.
The locations below are sequenced from highest-priority to supporting - most stores start with entrances and add zones progressively as their analytics maturity grows.
Of course, every people counting deployment begins at the main entrance. This is where total visitor volume is established - the denominator in your conversion rate calculation. Without an accurate entrance count, no other metric in your store analytics stack is reliable.
VemCount sensors at the entrance can exclude staff entering and exiting during shift changes - a source of count inflation that can distort daily visitor figures by 5-20% in high-staff stores. The employee exclusion system uses anonymised tagging, not video recording. No personally identifiable information is stored at any point.
Placement guidance: mount above the door frame at a height of 2.4-3.5 metres, centred over the entry path. For wide entrances exceeding 3.5 metres, Vemco teams will guide you for the most accurate footfall counting.
Stores with multiple entry points - a mall-facing door and a street-facing door, for example - lose data accuracy the moment they count only one of them. Every unmeasured entrance is an untracked visitor segment, and those segments skew every downstream analysis.
Secondary entrance data also reveals which entry point drives the highest-value traffic. If 40% of visitors enter through the mall corridor but that group converts at twice the rate of street-level visitors, the store layout, product placement, and promotional strategy for each zone should differ accordingly.
Placing sensors at or near the checkout area - with POS integration - closes the loop between visitor data and transaction data. This is where conversion rate is calculated at its most granular: visitors who passed through the store versus visitors who completed a purchase.
Store conversion rate analytics via VemFusion connects VemCount to 50+ POS and BI systems via open API, requiring no custom development. Once the integration is live, dashboards update in real time - store managers or retail brand's headquarters see today's conversion rate, this hour's footfall traffic, and peak period comparisons without manual data exports.
Not all floor space generates equal visitor engagement. Seasonal displays, new arrival sections, and end-of-aisle promotional fixtures may draw 60-70% of visitor dwell time while occupying 20% of floor space - or they may be largely ignored despite significant merchandising investment.
Sensors positioned above high-traffic zones measure dwell time, zone entry rate, and peak engagement zones. This data directly informs product placement, visual merchandising decisions, and promotional ROI calculations.
In stores where VemTrack is deployed alongside VemCount, customer journey heatmaps of the full store layout make zone performance patterns immediately visible without requiring sensor-by-sensor data analysis.
With our AI supported RE-ID technology, you can event track individual visitor insights anonymously. VemTrack provides all insights you need for leveraging existing people counting data and increase your sales conversion.
In larger retail formats - department stores, supermarkets, DIY retailers - sensors positioned at the transitions between departments reveal category flow: which categories visitors move between, in which sequence, and which categories are bypassed entirely.
This data answers a specific question that footfall data alone cannot: are visitors finding the categories they came for, or are they navigating around the store inefficiently? Category transition data informs store layout redesigns that reduce navigation friction, increase cross-category exposure, and extend average visit duration.

A sensor positioned to face the storefront measures how many people stop in front of the window display and how long they stay. That combination - engagement rate and dwell time - tells you whether a window is working before a single person walks through the door.
This matters most in seasonal transitions and campaign periods. When a new window goes up, storefront analytics shows within days whether foot traffic is stopping to engage or walking past. That is a real A/B test: run two window configurations across two locations, compare passerby engagement rate and dwell time, and carry the version that performs into the broader rollout. Without measurement, window decisions are made on intuition and visual preference. With storefront data, they are made on observed behaviour.
Passerby engagement rate and dwell time also shift by time of day, day of week, and weather conditions - patterns that inform when a window needs to work hardest and whether it is doing so.
Bonus: If your footfall counting sensor is positioned at the entrance with the right angle, a single device can simultaneously measure passerby volume, store entries, and customer demographics - giving you capture rate, footfall count, and audience breakdown from one installation point.

Shelves in parallel rows with defined main aisles benefit from sensors at aisle intersections and category entry points. The grid structure creates natural measurement nodes that map directly to department-level analytics.
Common in fashion, homeware, and premium retail, open floor plans require sensors that define zones rather than aisles. Placement at the perimeter of each merchandising cluster establishes zone boundaries and measures capture rate: the percentage of visitors who enter a given zone relative to total store visitors.
Department stores and large-format retailers require sensors at every stair bank, escalator, and lift. Floor-by-floor visitor distribution data reveals which floors are underperforming relative to their footfall allocation and guides decisions about floor-level assortment, staffing, and event activation. For a broader view of how retail footfall analytics applies across store formats, Vemco's retail industry page covers the full use case landscape.
Getting the sensor in the right location is the first step. Getting it to talk to your analytics platform is the second - and this is where many deployments lose time.
Vemco solutions are compatible with sensors from 50+ hardware manufacturers via VemFusion, an open API integration layer that connects counting data from any supported sensor directly into VemCount dashboards. Whether you are deploying new hardware or connecting an existing sensor estate, Vemco handles the data pipeline without custom development. This matters in practice because most multi-site retailers do not run a single sensor brand across every location - VemFusion consolidates mixed hardware into one analytics environment.
On the installation side, Vemco's team supports the setup and configuration process - covering sensor placement, network connection, and initial data validation. Post-installation, accuracy is confirmed against a manual count baseline. VemCount consistently delivers 98%+ accuracy on this benchmark across retail deployment types.
Support does not stop at go-live. Vemco runs regular automated health checks on connected sensors, monitoring data stream integrity and flagging anomalies before they affect reporting. If a sensor drops off, sends irregular counts, or falls outside expected accuracy parameters, the issue is identified and addressed - without the store manager needing to notice a problem in their dashboard first. Placing a sensor correctly and connecting it to a platform is the foundation. Keeping that data reliable over time is what makes the difference between an analytics setup that works on launch day and one that continues to deliver accurate data six months later.

VemCount does not store video recordings. Visitors are processed as anonymous data points at the moment they pass a sensor - no images, faces, or personally identifiable information are retained at any stage. The system is fully GDPR compliant and has been deployed across retail operations in all 8 of Vemco's EU language markets.
VemCount connects to sensors from 50+ hardware manufacturers via VemFusion's open API - including Axis, Hikvision, Xovis, Milesight, and others. Mixed-hardware deployments across multiple locations all feed into a single VemCount environment, with no separate platform per sensor brand.
Yes. A sensor positioned at a slight outward angle at the storefront can simultaneously capture passerby volume, stop and engagement rate, store entry rate, and demographic data - demographic distribution - without storing any personally identifiable information. This gives store managers capture rate data and audience insight from a single device.
VemCount achieves 98%+ counting accuracy across retail deployments, validated against manual count baselines post-installation. Accuracy is maintained across variable lighting conditions, peak footfall periods, and wide entrance configurations through 3D stereoscopic sensor technology and real-time data filtering.
Yes. VemCount is deployed across 1,000+ businesses in 98+ countries and supports centralised multi-site analytics. Store managers view location-level data; regional and head office teams access aggregated dashboards across the full estate in a single platform.
Accurate footfall data starts with correct sensor placement. The seven locations above - entrance, secondary entries, checkout zone, high-traffic displays, department transitions, storefront, and fitting rooms - together provide a complete picture of how visitors move through your store, where conversion happens, and where it does not.
3D stereoscopic sensors deliver the highest accuracy in retail environments, consistently reaching 98%+. Unlike single-plane infrared beams - which struggle with bidirectional traffic and crowded entrances - 3D sensors use depth imaging to distinguish individuals even in dense foot traffic and variable lighting conditions. AI-supported filtering built into VemCount processes the raw sensor data in real time, removing staff movements, correcting edge-case errors, and flagging anomalies automatically. The result is a cleaner, more reliable count than any sensor hardware alone can produce.
Most people counting sensors are straightforward to mount physically - in many cases a ladder and a power connection are all that is needed. Where Vemco adds value is in what comes after mounting: calibration, network configuration, and validation against a manual count baseline. Vemco’s team handles all of this remotely or on-site depending on the deployment, and conducts regular automated health checks on connected sensors to catch data issues before they affect your reporting.
