Density measurement that ships counts, not identities
A passive Wi-Fi pedestrian sensor with on-device aggregation. Device identifiers are discarded on the Collector itself — only aggregate counts ever leave it. Designed for the safe-harbour described in the ICO's 2016 Wi-Fi Location Analytics guidance, and built for councils, BIDs, retailers and workplaces who need defensible footfall data in 2026.
Why Crowd-Sense
Most Wi-Fi analytics products from the past decade hash MAC addresses and retain them in a back-end database. Crowd-Sense doesn't. Identifiers are discarded on the Collector at aggregation close. There is no off-device dataset to re-balance, subpoena, or breach.
Privacy by architecture
MAC addresses never leave the Collector. Not hashed, not salted — discarded entirely. The wire payload contains no identifier of any kind.
Honest by default
We publish the MAC randomisation overcount curves. Density and trend are reliable; absolute unique-visitor counts at long windows are not, and we say so.
Self-installing
Plug into mains via USB, connect Ethernet or Wi-Fi, capture begins within minutes. No civils, no scaffolding, no specialist trade.
Hosted, no CapEx
The Collector is supplied as part of the subscription. The customer owns no hardware, maintains no hardware, replaces no hardware.
Real-time
Density at 1, 5, 15, 30 and 60-minute windows. Operational decisions made on minute-level data, not weekly batches.
Established 1994
Visual Solutions (UK) Ltd has been operating continuously since 1994. Procurement-grade due-diligence, not a fresh-vehicle startup.
Built for these segments
Same Collector, four positioning lanes. Pick the one that fits.
Councils & BIDs
Hosted footfall data subscription. No customer hardware. A defensible alternative for any authority that needs numbers it can publish.
View →Pubs & venues
Always-on density sensing for pub groups, gastropubs, multi-site hospitality. Priced for the operator, not the agency.
View →Retail & high street
Honest density for SMB retail, market stalls, kiosks. Sub-£500 per site per year. Zone and outside-catchment signal cameras can't deliver.
View →Workplaces
Building pulse without the bossware. Floor and zone density for HVAC, cleaning, ESG and capacity planning — in the works-council era.
View →The Oxfordshire moment
In January 2026 Oxfordshire County Council publicly withdrew the November 2025 Oxford congestion-charge footfall figures after a mid-2025 dataset rebalance from its supplier produced anomalies the council couldn't defend.
The lesson generalises. Any organisation that buys footfall data without understanding the methodology behind the numbers is one supplier-side change away from the same press cycle. Crowd-Sense is built to give a different answer: each Collector produces counts directly from its own local observations. There is no panel to rebalance, no third-party SDK, nothing that could change without us deliberately changing it.
What we mean by "no panel": we don't aggregate location data from mobile apps. We don't buy data from brokers. Each Collector passively listens for nearby Wi-Fi probe requests, counts them on-device, and emits aggregate bracket counts. That's the whole pipeline.
