WASHINGTON, July 16 — Body cameras, once discussed primarily in the context of police accountability, have quietly expanded into a broader range of uses that now span commerce, healthcare, military operations, journalism, and even recreational activities like cycling. These wearable audio, video, and photographic recording systems — also referred to as bodycams, body-worn video, or wearable cameras — are no longer a single-purpose device. Their best-known application remains law enforcement.
But the technology itself has evolved. Action cameras, a related category, are typically compact, rugged, and waterproof at the surface level, relying on CMOS image sensors.
They can capture photos in burst mode and time-lapse mode, and record high-definition video. As of 2019, mid-range to high-end action cameras could record 4K video at 60 frames per second, with slow-motion video recording at 120 or 240 fps also common.
Mixed Evidence on Police Use
Research on the impact of body-worn cameras for law enforcement shows mixed evidence. Studies have not produced a clear consensus on whether the devices reduce use of force by police or improve communities’ trust in law enforcement. The publicized deaths of black Americans at the hands of police have been a large factor increasing support for body-worn cameras by police personnel.
For decades, people have protested police by watching them. This practice stems from long-term unhappiness with the system, and social media has bolstered this public behavior.
The cameras, in this context, serve as tools for both official oversight and citizen sousveillance — a term that describes recording from the perspective of the public rather than authorities.
Beyond Law Enforcement
Outside policing, body cameras now serve in covert surveillance, military training, and healthcare settings where recording patient interactions or procedures may aid documentation and training. Journalists have adopted them for field reporting, and cyclists use action cameras for safety and recreation. The devices have become smaller, more durable, and more capable over time.
The encouraging part for consumers is the growing accessibility of these devices. Mid-range models now offer features that were once reserved for professional equipment.
Patients and consumers should talk to their doctor or a qualified professional before using body cameras in healthcare or sensitive personal contexts, as privacy and consent considerations vary by jurisdiction. What to watch next: As the technology continues to improve and prices drop, the range of applications will likely widen further. Researchers and policymakers will be watching whether clearer evidence emerges on the effectiveness of body cameras in law enforcement, and whether new uses in healthcare and journalism raise additional questions about privacy and data management.
As always, patients and consumers should consult their doctor or a qualified professional for guidance specific to their situation.
