Outline

This paper presents the results of a real-world application and evaluation of an AI-based Smart Video Solution (SVS). SVS integrates with existing infrastructure camera networks, prioritizing privacy and ethical standards, and utilizes pose-based data to perform AI tasks such as anomaly detection. It provides real-time alerts via cloud-based infrastructure and a mobile app, and utilizes innovative data representation and visualization techniques, such as occupancy indicators, statistical anomaly detection, bird's-eye views, and heatmaps, to understand pedestrian behavior and enhance public safety. SVS is deployed and evaluated using 16 cameras in a community college environment, demonstrating the robustness of a system that integrates AI-based visual processing, statistical analysis, database management, cloud communication, and user notification. Specifically, we validate the system's real-time performance by evaluating the end-to-end latency from anomaly detection to notification to stakeholders. For 21 hours, the system efficiently managed 16 CCTV cameras with a consistent throughput of 16.5 frames per second (FPS), with an average end-to-end latency of 26.76 seconds.

Takeaways, Limitations

Takeaways:
Demonstrates the potential of AI-based SVS to improve public safety in real-world environments.
Presenting practical AI technology applications through easy integration with existing infrastructure.
Effective information delivery and decision support through innovative data visualization technologies.
Validating the efficiency and reliability of a real-time abnormal behavior detection and notification system.
Providing actionable information for a wide range of stakeholders (law enforcement, urban planners, social scientists, etc.).
Limitations:
The evaluation environment was limited to a community college, requiring further research on generalizability.
Because the system is limited to 16 cameras, further research is needed to address potential issues that may arise when scaling to a larger system.
Lack of in-depth discussion of privacy and ethical issues.
Lack of system performance evaluation in various environments and situations.
Additional review of system stability and maintenance is required for long-term operation.
