What’s the Difference Between BWV and BWC Systems?
Introduction
When evaluating video technology for law enforcement, agencies often encounter the terms Body-Worn Video (BWV) and Body-Worn Camera (BWC). While related, these terms describe distinct concepts that impact policy, procurement, and operational use. Understanding the differences ensures departments select the right systems and develop effective protocols for accountability, evidence collection, and public trust.
Defining Body-Worn Cameras (BWC)
Body-Worn Cameras are physical devices worn by officers to capture video and audio during their shifts. Key features include:
-
High-definition video recording
-
Automatic or manual trigger activation
-
Integrated microphones for clear audio capture
-
Durable, rugged design for daily field use
-
Compatibility with Digital Evidence Management Systems (DEMS)
BWCs are the tangible hardware officers carry, and they serve as the primary tool for documenting interactions with the public.

Defining Body-Worn Video (BWV)
Body-Worn Video refers to the overall system of capturing, storing, and managing footage collected by BWCs. It includes:
-
Video and audio footage captured in the field
-
DEMS platforms for secure storage and retrieval
-
Data encryption and access controls
-
Policies for activation, retention, and public release
-
Integration with other police technologies
BWV encompasses both the recording process and the management of digital evidence, making it a broader concept than the physical camera alone.

Key Differences Between BWCs and BWV Systems
| Feature | Body-Worn Camera (BWC) | Body-Worn Video (BWV) System |
|---|---|---|
| Hardware | Physical camera device | Encompasses cameras, DEMS, and software |
| Purpose | Capture video and audio | Manage, store, and analyze footage |
| Management | Limited to local device storage | Full system integration with encryption, access control, and retention policies |
| Policy Integration | Guidelines apply to device use | Includes activation, redaction, and evidence handling policies |
| Scope | Single officer | Department-wide system and workflows |
Understanding this distinction helps agencies plan for both procurement and long-term program management.

Why the Distinction Matters
-
Procurement Decisions: Agencies must budget for both devices (BWCs) and system infrastructure (BWV).
-
Policy Development: Policies should cover both the use of cameras and the management of video data.
-
Training Programs: Officers need to understand camera operation, while administrators focus on data handling.
-
Integration with Other Tech: BWV systems often integrate with CAD, RMS, and prosecutorial platforms for seamless workflow.
Recognizing the difference ensures departments implement a complete and effective body-camera program.

Conclusion
BWCs and BWV systems are complementary but distinct components of modern law enforcement technology. BWCs are the physical devices capturing footage, while BWV encompasses the entire system of managing, storing, and securing that video. Departments that understand and plan for both hardware and software aspects can maximize accountability, improve evidence handling, and strengthen public trust.
