EgoPolice: A Benchmark for Egocentric Video Understanding in High-Stakes Police Body-Worn Camera Footage
Summary
EgoPolice is a new benchmark dataset comprising over 180 hours of real, egocentric police body-worn camera (BWC) footage, curated from publicly available videos of police-civilian interactions. It features second-by-second annotations for nine critical action labels, including "Weapon Out" and "Physical Interaction." The dataset presents significant challenges for video understanding models due to rapid camera motion, dense human interactions, and rare high-stakes events, which lead to visual degradation and limited global appearance cues. Benchmarking state-of-the-art models, including VideoMAE V2, X-CLIP, and Gemini 2.5 Pro, revealed that while video-pretrained models perform better in classification, even Gemini 2.5 Pro achieved only 76.9% accuracy on 1-minute clips and struggles with high-risk actions, indicating unsuitability for autonomous deployment. EgoPolice aims to provide a foundation for human-in-the-loop systems to efficiently identify events in vast BWC archives.
Key takeaway
For AI Scientists and Computer Vision Engineers developing systems for sensitive, real-world environments like law enforcement, recognize that current video models, including Gemini 2.5 Pro, are not yet reliable enough for autonomous deployment in high-stakes body-worn camera analysis. You should prioritize human-in-the-loop workflows where AI assists human reviewers by surfacing potentially critical video segments for verification. This approach mitigates the risks of unexamined bias and system failures, enabling scalable auditing and retrospective analysis while preserving human judgment.
Key insights
Egocentric police BWC footage presents unique, high-stakes challenges for video understanding models, requiring specialized benchmarks and human oversight.
Principles
- BWC footage demands motion-robust, context-aware egocentric perception.
- Objective, intent-free action definitions reduce annotation subjectivity.
- Model reliability in high-stakes domains requires rigorous, domain-specific benchmarks.
Method
A two-stage annotation pipeline filters interactions, then labels 9 objective action categories at per-second granularity, using a custom web tool and mental health safeguards.
In practice
- Use EgoPolice to benchmark video models in high-stakes egocentric settings.
- Deploy models in human-in-the-loop systems for BWC footage review.
- Prioritize video pretraining for robust BWC action recognition.
