How accurate are occupancy sensors?

Occupancy sensors vary widely in accuracy, but radar-based sensors are currently the most precise and the most privacy-safe option available.

Accuracy depends on the sensor type. Basic motion sensors may only detect activity, not actual presence. More advanced sensors like radar can distinguish individuals, count people accurately in real time, and maintain complete anonymity—no cameras, no personal data.

Why radar wins on both accuracy and privacy

Radar sensors use radio waves to detect and track people’s movement with precision. Unlike cameras or WiFi sniffers, radar doesn’t collect images or device IDs—making it the only option that excels in both real-time accuracy and built-in privacy.

Radar can:

  • Count people with near-perfect accuracy, even in large or dynamic environments
  • Work in low-light or no-light settings\
  • Respect employee privacy, avoiding any perception of surveillance

Privacy Without Compromise

Radar sensors detect shapes and motion without ever capturing personal identifiers. This makes them ideal for organizations navigating privacy regulations (like GDPR or HIPAA) or employee trust issues around monitoring.

Summary

Occupancy sensors range in accuracy—but radar stands out as the most accurate and privacy-first technology available. If you need trustworthy data without compromising anonymity, radar is the gold standard.

How do I know if my office space is being wasted?

You can tell if your office space is being wasted by measuring how often each space is used—and occupancy sensors provide the real-time data you need to find out.
If desks, meeting rooms, or entire floors are consistently empty or underutilized, that’s space (and money) going to waste. Tools like Density’s Waffle and Atlas help companies assess usage accurately so they can cut costs and improve the workplace experience.
