Density offers a powered, privacy-first alternative to Butlr
With workplace insights delivered reliably and accurately.
A closer look
Considering a switch to Density? Or maybe you’re just starting to research occupancy sensors? We put together this side-by-side comparison to show how Density and Butlr are different.
Area
Space
Fast refresh rate (< 1 sec)
3D radar offers the highest accuracy and is the highest-performing, non-camera sensing technology
Does not capture personally identifiable information (PII)
Waffle: No installer required
Open Area/Entry: Overhead install (installer needed) required for cabled options
$$ for Entry and Open Area
Area
Battery requires maintenance (2 years marketed but customers say battery life may be as little as 1/4 of advertised rate in busy areas)
Medium data refresh rate
(Lowering sampling rate to save power means data cannot actually be real time)
Thermal sensors can struggle with telling people and heat-emitting objects apart. A laptop may be counted as a person.
No PII captured
Overhead install (installer needed) required for hubs
$$ < $150-$499
$$$ $500-$1000+
Breaking it down
Here are some key points to consider when deciding on what workplace measurement solution to go with.
Density may be better if…
You care
about privacy
With Density, privacy is built in. Our sensors use radar, not cameras, lenses, or microphones—so there’s no PII captured at the source, ever. Butlr uses thermal sensors and relies on anonymizing the data after the fact.
Downtime
is your enemy
You need 100% uptime and that’s exactly what Density delivers. Our sensors are powered (not battery-operated), meaning no unexpected gaps in data due to dead batteries. Butlr sensors run on batteries, which can result in data loss when they run out.
Accuracy
is everything
Density’s 3D radar technology provides highly precise occupancy data, distinguishing between multiple people standing side by side. Butlr’s thermal technology can have trouble counting people—a person wearing a hat might not be counted but a hot coffee mug could be.
Butlr may be better if…
You don’t have easy access to power
Because Butlr’s sensors are battery powered, you don’t need access to power outlets.
Directional data is good enough
With easy install, Butlr’s thermal sensors can be set up quickly to provide high-level insights. Think how many people are coming in and out of a floor.
Senior living is a use case
Butlr has tailored some sensors specifically for senior living, helping detect potential risks and keep residents safer. Density, for now, isn’t focused on that space.
