What is dwell time?

Dwell time is a term commonly used in the field of retail and transportation which refers to the duration of time an individual spends in a particular location or area. It provides valuable insights into human behavior, allowing businesses and organizations to understand customer engagement, optimize space utilization, and improve operational efficiency. With the advancements in sensor technology and video analytics, measuring dwell time has become increasingly accurate and efficient, revolutionizing the way we analyze and interpret human presence.

Why dwell time matters for B2B operations

Understanding dwell time is a key driver for operational efficiency and safety:

• Retail: From dwell time in the whole store, over dwell time in specific areas to differentiation of dwell time with and without staff engagement - for retailers dwell time is a core KPI to measure and optimize store performance.
• Public Transit & Rail: High dwell times of trains or passengers at platforms cause delays and overcrowding. Accurate measurement helps operators optimize schedules and dispatch personnel.
• Airports & Aviation: Monitoring dwell times in check-in areas, security lines, or on the apron, e.g., aircraft turnaround times directly improves passenger throughput.
• Smart Cities: Analyzing how long people stay in specific public squares helps urban planners and business owners optimize space utilization and safety layouts.

How to measure dwell time?

To gather accurate dwell time metrics, organizations typically choose between two main technological approaches:

Traditional hardware-based sensors

Devices such as infrared, thermal, radar, or LiDAR sensors are physically installed in specific areas to detect presence. While useful, they often come with high hardware installation costs, limited coverage areas, and lack the ability to provide deeper contextual data, e.g., distinguishing between a passenger and a staff member.

Next-generation AI Video Analytics

Instead of buying expensive new hardware, modern organizations leverage AI video analytics software. By integrating with your existing security cameras, intelligent deep learning algorithms detect anonymously people, objects and vehicles and track their dwell time across defined zones in real-time.

How to implement dwell time analytics?

Implementing an automated dwell time measurement system with Video Analytics by Isarsoft is highly streamlined:

1. Camera integration: Connect the software to your existing IP cameras. No physical alterations to your infrastructure are needed.
2. Edge or cloud configuration: The software runs either locally on edge-gateways (on-premise) or centralized in the cloud, processing the video stream locally to extract anonymous dwell time metrics.
3. Actionable BI insights: The processed, structured data is sent directly to your Business Intelligence dashboards or control room applications to trigger alerts when predefined dwell time thresholds are exceeded.

100% GDPR compliance with dwell time measurement by Isarsoft

When measuring dwell time in public or commercial spaces, data privacy is highly relevant. Unlike legacy tracking methods that rely on Wi-Fi tracking or facial recognition, Isarsoft Perception utilizes privacy-by-design technology:

• 100% anonymized: The AI analyzes movement patterns without identifying individuals or storing personal features.
• GDPR compliant: No video data needs to be saved or sent to external servers. Processing can happen entirely on-premise.
• Public trust: By analyzing pixel coordinates instead of faces, organizations can guarantee maximum privacy protection while still receiving highly accurate operational data.

Outlook

Dwell time measurement has become a valuable tool for analyzing human presence in various environments. Through the use of sensors and video analytics, organizations can gain insights into customer behavior, optimize resource allocation, and improve operational efficiency. For retailers dwell time measurement means understanding how customers navigate your stores. Discover how dwell time helps improving product displays, store layout and boost conversion rates.
