Comparing Different Types of People Counting Technology

Comparing Different Types of People Counting Technology

Choosing the right people counting solution is crucial for accurate data, privacy, and operational efficiency. Here’s how today’s leading technologies compare—and why Wellpoint’s camera-free, Time-of-Flight (ToF) laser sensors stand out. 📡📊

 

 

1. Camera-Based Systems

  • How it works: Uses video (monocular or stereo) and AI to detect and count people in real time.
  • Pros: High accuracy (up to 98%), advanced analytics (heatmaps, dwell time, demographics), can use existing CCTV infrastructure.
  • Cons: Raises privacy concerns, requires image processing, may be affected by lighting or obstructions, and can be costly if cameras are not already installed.

2. Time-of-Flight (ToF) Laser Sensors

  • How it works: Emits laser pulses and measures their return time to detect and count people—no cameras or images.
  • Pros: Highly accurate, works in any lighting, privacy-first (no images or personal data), real-time analytics, easy integration, GDPR compliant.
  • Cons: May require multiple devices for very wide entrances but easily scalable.

3. Thermal Sensors

  • How it works: Detects body heat to count people, even in darkness.
  • Pros: Works in low light, privacy-friendly (no images).
  • Cons: Accuracy drops in sunlight or crowded conditions, struggles to distinguish between closely grouped people or objects with similar temperatures.

4. Infrared Beam (Break-Beam) Sensors

  • How it works: Counts each time a beam is interrupted at a doorway.
  • Pros: Low cost, easy to install, privacy-friendly.
  • Cons: Lower accuracy in busy or wide entrances, no data on direction, dwell time, or group size.

5. Wi-Fi Tracking

  • How it works: Detects smartphones’ Wi-Fi signals to estimate occupancy.
  • Pros: Covers large areas, no physical installation at entrances.
  • Cons: Only counts people with Wi-Fi-enabled devices, less accurate, privacy concerns over device tracking.

6. Manual Counting

  • How it works: Staff use clickers or tally counters to count entries/exits.
  • Pros: Simple, low-tech, no installation needed.
  • Cons: Labor-intensive, prone to human error, not scalable or real-time, no integration with digital systems.
