§ 02 / Technology

Passive sensing, patented from antenna to algorithm.

Our sensors listen for the location-service signals that mobile phones already emit. No camera. No transmission. No personal information — ever. Here’s how it stacks up against everything else on the market.

§ 02.1 / Comparator

DFRC vs. WiFi APs, cameras, mobile apps.

Every footfall-measurement technology has trade-offs. Here’s the honest one.

	DFRC IoT sensors	WiFi access points	Counters & cameras	Mobile app location
Hardware	Required	Required	Required	None
Software	Dashboard, API, App	Dashboard, API, App	Dashboard, API, App	CSV exports
Data ownership	Exclusive	Exclusive	Exclusive	Shared
Accuracy	90% minimum	Less accurate*	Less accurate, needs reboot	Accurate when app is active
Counting method	Mobile phone signals	Mobile phone signals	People	Mobile app data
Range	Up to 100 m	Varies	Gate or line of sight	Unlimited
Limitation	Mobile device required	Mobile device required	Environment dependent	Privacy & user consent required

* Solutions based on access points listen to a single WiFi band — while solutions based on Software-Defined Radio (such as DFRC’s) listen to all bands. Access-point solutions therefore miss passers-by who only linger briefly.

§ 02.2 / Patents

11× patented, from how we sense to how we store.

Detection is built on a Software-Defined Radio listening passively to probing signals used for location services. No personal information is collected. No content of devices is read.

300%^{* more efficient}

Our patented scanning algorithm detects up to 300% more devices than competing sensors, and uniquely identifies each one so the same phone is never double-counted.

01 · Passive

No transmission

Sensors only listen. They generate no electromagnetic transmission and never touch device content.

02 · Encrypted

One-way MAC hashing

A patented one-way encryption ingests every MAC address. The original address cannot be recovered.

03 · Compliant

PDPA / PIPA / GDPR ready

In SG & KR, encrypted MACs without auxiliary data are not personal data. In the EU, processing happens on-sensor — only aggregated results leave the device.

De-randomisation, solved.

iOS and Android rotate MAC addresses every second to hide identity — making one phone look like five different devices. Solutions that use a fixed ratio between randomised and non-randomised addresses are not accurate (the ratio is location and time-dependent). We reconcile them back into one.

§ 02.4 / The Dashboard

A working preview, not a screenshot.

Click through the modules in the sidebar. Switch sites in the top bar. Toggle the heatmap. The data is illustrative — the interactions are real.

The Dashboard lets you fetch data in real time, wherever you are, whenever you need it · nine modules covering site overview, mapping, heatmap, mobility, analytics, asset tracking, alerts and (D)OOH valuation.

§ 02.4 / The Dashboard

Nine modules. One workspace.

The interactive preview is best on a wider screen — here’s what the Dashboard covers. Switch sites, toggle the heatmap, set alert thresholds, value (D)OOH inventory: it’s the same data your team would see in production, in real time.

Data

Site overview

KPIs, hourly footfall, returning visitors and dwell distribution at a glance.

Data

Insights map

Filter by region and date, then read footfall on top of a stylised basemap.

Data

Heatmap

Density per square metre, updated every second.

Data

Mobility

Top visitor paths between zones, with arrowed flow overlays on the map.

Data

Analytics

Visitor counts and dwell over time with prediction bands.

Data

Asset tracking

Locate tagged assets and surface anomalies (missing tags, distance shifts).

System

Alerts

Threshold rules per region (crowding, dwell, missing assets) with severity tiers.

OOH

Hourly valuation

Estimated transaction value per hour, by day — useful for billboard pricing.

OOH

Property valuation

Per-region revenue contribution and ranking for (D)OOH inventory.

§ 02.5 / API

Or skip the dashboard and bring the data to where you work.

Three endpoints cover most use cases: Floating Population (real-time count), Visitor Count (historical count), and Sensor Health.

REST · JSON

Integrate in an afternoon.

Bearer-token auth, per-region or aggregate queries, second-level resolution. Drop it into Grafana, Tableau, Power BI or your custom dashboard.

→ GET /floating-population — real-time count
→ GET /visitor-count — historical count by region
→ GET /sensor-health — per-sensor status
