ABOUT ME

Effective Solutions for Managing Police Body Camera Video

Takeaway Ideas

o Law enforcement needs a better way to manage body camera video

o Using semantics to help analyze video can reduce effort and improve usage

o Solution requires integrating multiple types of systems and capabilities

How Effective are Body Video Cameras?

What’s the Problem?

What’s the Problem?

As more police agencies equip officers with body cameras in response to public pressure, authorities are discovering they create problems of their own: how to analyze, process and store the mountains of video each camera generates.

What’s the Problem?

Right now, there are too many body camera videos being produced for law enforcement agencies to effectively analyze

What’s the Problem?

This problem is being compounded daily by more cameras producing more videos that are simply being stored to a cloud system

What’s the Problem?

The cameras create an enormous amount of data. Who gets access to it? How does it get stored? What appeared to be a no-brainer in terms of bringing accountability to the force has raised a lot of ancillary questions.

Our Areas of Research

Video manageme

nt

Semantic Extraction

Standardized

vocabularies

How can agencies determine if there is relatively important evidence on a video?

How should video be created and stored?

Can we create a unified ontology for all levels of law enforcement?

What’s the Solution?

What’s the Solution?

Upload and manage videos

Analyze text for semantic meaning

Automatically extract text and metadata from videos

Query to discover key ideas and specific words within videos

?

What Does Each Provide?

Provides the online video storage and processing, plus advanced video management

What Does Each Provide?

Provides the video to text extraction service plus keyword tagging capability

What Does Each Provide?

Provides the semantic analysis capability plus the ontology management

What Does Each Provide?

Provides the services and integration capability

Challenges Ahead

Scalability

REGULATION Privacy50 states have different regulations regarding video usage

Most police agencies are small to midsize and have limited budgets

Just because video can be used, who gets to see it?

Our Next Steps

Proof of Concept

Scaled Testing

Overcome Doubt

Need to validate how large the solution can be

Working with a few agencies now for PoC

Police are naturally wary of being recorded
