Butlr alternative

Butlr’s thermal sensors excel at workplace privacy, but they are sensor-only. Crowd Connected gives you occupancy counting, asset tracking, and wayfinding in one composable platform, built for any environment.

Location data from a wide area made accessible
Butlr is a thermal sensor company founded by MIT researchers. Their Heatic sensors detect body heat rather than using cameras, making them genuinely privacy-first. The sensors are battery-powered and wireless, designed primarily for workplace occupancy counting. They focus on detecting presence and headcount in office environments, avoiding cameras entirely.
Butlr strengths

What Butlr does well

Butlr’s thermal approach is genuinely innovative for privacy-conscious organisations. Their sensors detect body heat through walls, require no cameras or visible surveillance infrastructure, and operate on battery power. For workplace teams worried about employee monitoring, the privacy-first positioning is compelling. The sensors work reliably in offices where privacy concerns are paramount.

However, thermal sensing has real constraints. Butlr’s sensors detect presence and headcount only, with no positioning data or wayfinding capabilities. You typically need roughly one sensor per ten square metres at standard ceiling heights of 2.5 metres - that’s eight to ten times as many sensors as Crowd Connected’s Bluetooth approach, which covers 80 to 100 square metres per beacon. Battery sensors need periodic replacement cycles. And their platform is built specifically for workplace use, limiting application to other sectors like education, events, or healthcare venues.

Why Crowd Connected offers more

Crowd Connected combines occupancy counting, asset and people tracking, and wayfinding in a single composable platform. Our approach uses battery-powered Bluetooth sensors that passively detect phones and devices, converting device counts into people counts via self-calibrating machine learning algorithms. No cameras, no thermal imaging, no wired infrastructure.

One infrastructure powers three capabilities: occupancy sensing, tag tracking for assets and people, and wayfinding. Our pricing is transparent and published on our website. We serve education, healthcare, events, and venues as well as workplaces. Our REST APIs and modular architecture mean you integrate the specific capabilities you need, avoiding vendor lock-in.

Why choose Crowd Connected?

One infrastructure, three capabilities

Occupancy sensing, tag tracking for assets and people, and wayfinding all powered by a single battery-powered sensor network. Not sensor-only limitations.

Fewer sensors per room

Detect phones passively with wider coverage per sensor. Room-level occupancy without dedicated per-room hardware like thermal sensors require.

Built for education

Universities need campus-wide coverage. Our platform handles lecture theatres, libraries, corridors, and open spaces at scale.

Privacy first

Like Butlr, we prioritise privacy. No cameras, no thermal imaging, anonymised device detection. Full control over what is collected and where.

Frequently asked questions

How does Crowd Connected's approach differ from Butlr's thermal sensors?
Butlr uses thermal sensors for headcount only. Crowd Connected uses battery-powered Bluetooth sensors that passively detect devices in proximity, converting device presence into accurate people counts via self-calibrating machine learning. One infrastructure powers occupancy, tag tracking, and wayfinding. You get a complete location platform instead of sensor-only headcount.
How many sensors does each solution need per room?
Butlr requires roughly one thermal sensor per ten square metres. Crowd Connected covers 80 to 100 square metres per beacon - so you need eight to ten times fewer sensors. That means lower hardware costs, simpler deployment, and the same infrastructure also powers tag tracking and wayfinding.
Is Crowd Connected as privacy-friendly as Butlr?
Yes, equally privacy-first. We use no cameras and no thermal imaging. Device detection is anonymised, and venue-boundary restrictions ensure data collection is limited to your specific spaces. Full organisational control over what is tracked and stored.
Can Crowd Connected work in education environments?
Absolutely. Universities, schools, and campuses are core use cases. We handle lecture theatre counting, library occupancy, campus-wide wayfinding, and building-level analytics across any institutional footprint.
What about Butlr's battery-powered sensors? Does CC offer something similar?
Yes, we use battery-powered Bluetooth sensors that need no cables, screws, or external power. Our mesh network architecture means one gateway per building. But because we detect phones rather than heat signatures, you need fewer sensors overall, reducing infrastructure costs and complexity.
How does pricing compare?
Crowd Connected publishes transparent pricing on our website. Butlr’s previous G-Cloud pricing was around 133 to 209 pounds per sensor per year. Our pricing is typically significantly lower per square metre of coverage because each beacon covers eight to ten times the area of a thermal sensor.
OUR CLIENTS

Trusted across education, healthcare, and venues

Proven at scale

Deployed across universities, hospitals, and venues worldwide

Crowd Connected works with organisations across education, healthcare, events, and commercial venues in 30 countries. Each beacon covers 80 to 100 square metres - significantly wider coverage than dedicated room sensors - and the same infrastructure also powers occupancy counting, indoor wayfinding, and tag tracking. Canterbury Christ Church University, Buckinghamshire New University, Oulu University, and Aultman Hospital all use our platform.
