Beyond battery life: how the ecosystem brings out the best in the Axon Body 4

The most advanced Axon body-worn camera, Axon Body 4, is a cornerstone of the Axon ecosystem due to its ability to protect life by increasing officer safety and streamlining response, capture truth by recording interactions, and accelerate justice by streamlining evidence sharing.

The Axon Body 4 was purpose-built to be an incredible camera. Reliability and clarity are at the core of Axon’s imaging principles. Every design decision, from field of view (FOV) to low-light performance, is rooted in ensuring that the cameras support law enforcement professionals in the most challenging scenarios.The camera has a 13+ hour battery life, ensuring the camera is a reliable full-shift partner, even when real-time services like livestreaming are used. The benefits of this camera go far beyond other reliability improvements, however.

Let’s take a look at key features that make Axon Body 4 more than just a high-quality, reliable camera.

Real-time translation, agency policy queries, general knowledge inquiries and more with Axon Assistant

Axon Assistant is redefining the capabilities of body-worn cameras as a powerful AI voice assistant available directly within Axon Body 4. Designed to keep officers eyes-up with a push-to-talk operation, this voice assistant empowers officers in the field with the information they need, at the moment they need it.

Axon Assistant’s powerful capabilities include real-time translation across more than 50 languages, seamless access to general knowledge (like getting search engine results via voice), and instant voice-based readouts of agency-specific data like policy guidance.

Whether translating a community member’s speech, identifying hazardous materials, or querying departmental policies, Axon Assistant allows officers to enhance their situational awareness and decision-making.

As part of Axon’s broader AI Era Plan, Axon Assistant exemplifies how advanced BWC features can actively support officers in dynamic, high-stakes environments while preserving key interactions through automatic transcription and secure evidence capture.

Outcome Summary: Increase understanding between community members and police with instant translation for over 50 languages.

Make informed decisions with bi-directional communication and livestreaming

Enhance collaboration with Axon Body 4’s hands-free two-way communication feature, which enables field personnel to speak directly with command staff without tying up the radio.

This feature allows command staff and/or dispatch to talk to an officer in the field via the Axon Fusus desktop or mobile experience. In addition, livestreaming of video also allows support to have eyes on the situation in real-time. Officers can request livestreaming via a dedicated button on the camera whenever they’d like additional visibility and support from a supervisor.

Not only that, but Axon Fusus also makes it possible for officers to receive instructions from command staff who are simultaneously looking at data from different technologies like gun shot detection, ALPRs, and public/private video feeds. All conversations are recorded and uploaded to Axon Evidence as part of the evidentiary video, just like any other Axon body-worn camera recording.

Outcome Summary: Enhance situational awareness, officer safety and decision-making with Axon Fusus and bi-directional communications.

Manage and share evidence for faster resolution with Axon Evidence

Axon Body 4 footage is easily uploaded, stored, and managed in Axon Evidence, a powerful cloud-based DEMS. Axon Evidence breaks down silos by storing evidence in a centralized location while simultaneously eliminating the need for it to be stored on physical media.

Our 2024 digital trends report details how agencies are moving away from USB sticks and burned CDs to share evidence seamlessly and digitally via Axon Evidence. Jennifer Bragg, former IT Applications Senior Administrator for the Boulder Police Department, put it this way, “We had a couple of incidents where we ran the risk of the evidence being thrown out because we inadvertently didn’t share it…[so that’s why] we started putting everything into Axon Evidence.”

With Priority Evidence Upload, footage from Axon Body 4 uploads shareable evidence for stakeholders in a timely manner, especially in the case of critical incidents. This feature serves as an alternative method to driving back home or to headquarters and docking the camera before the evidence is ready.

Outcome Summary: Accelerate justice and maintain chain-of-custody for digital evidence with automatic uploads and tagging of AB4 data.

Help ensure crucial footage is captured with Axon Signal

Axon Signal Sensor wirelessly alerts nearby Axon cameras to begin recording the moment you draw your firearm; it’s unobtrusive and doesn’t affect the draw of your weapon.

Our partnership with Safariland brings broader holster coverage, with integrated holsters featuring a dedicated spot for the sensor, bracket-mount options, and even dedicated solutions to bring wireless activation for other uses of force, such as uses of handcuffs or OC spray.

Axon Body 4’s integration with Axon Signal’s hands-free activation technology means you can focus on the situation at hand, especially in the case of quickly-evolving or escalating scenarios, by activating cameras according to alert criteria. This increases officer safety simultaneously providing crucial transparency for agencies.

Outcome Summary: Preserve truth and help ensure key moments are recorded through automatic activations.

Save supervisor time and encourage the right behaviors with Priority Ranked Video Audit (PRVA)

Axon Body 4 technology can be leveraged in a training capacity as well. Features like Priority Ranked Video Audit (PVRA) make it possible to quickly find videos that contain language indicating specific behavior and surfaces footage with the highest volume of these keywords for review. According to our 2025 AI Trends report, supervisors save 12 hours per week on average using PRVA.

When a user audits footage, they click “Review Now” and begin watching the most relevant video based on keyword searching algorithms. Supervisors also have the option to watch multiple BWC feeds from the same incident as well as Axon Fleet footage in the same video player, in order to get multiple perspectives on an incident.

Agencies can customize their search to populate footage with specific phrases. This information can be used to identify areas for improvement or policy development.

Outcome Summary: Streamline your mandatory BWC review programs to save time and improve training.

Streamline evidence review with auto-transcription

Auto-transcription is yet another feature that makes Axon Body 4, within the context of the ecosystem, a unique public safety tool, not just another camera. AI is leveraged in Axon Evidence to quickly produce a transcript for investigative and evidentiary purposes. Axon Auto-Transcribe cuts the time needed to transcribe body-worn camera footage by 75%.

The Review Assistant allows users to quickly find names, addresses, and other critical moments from Axon Body 4 footage. This is a massive time saving feature that streamlines a variety of tasks, including producing court-ready transcripts.

Outcome Summary: Save 65-75% of your time when transcribing, searching and redacting evidence.

Create a quality first draft of a police report with Draft One

Axon’s advanced report writing tool, Draft One, is a critical time saving solution to prevent burnout and accelerate justice. Draft One leverages AI to convert speech to text from one or more Axon BWC recordings, creating a first draft of a police report for officers to review and edit rather than having to start from scratch, saving them time and getting them back into the field.

Audio from the footage is uploaded via LTE network and transcribed automatically so report drafts are available within five minutes of an incident ending. Draft One users must specify incident type before submitting, as well as sign off on the text to ensure its accuracy. These safeguards show our commitment to AI as a tool, never a replacement for the human element in policing.

Outcome Summary: Cut report writing time in half, giving officers more time to focus on time in the community.
