How to Get Live Video Feed from Your Action Camera Underwater

DJI Action Camera in Seavu Explorer housing capturing live underwater video feed

Introduction

Action cameras are great for capturing underwater footage, but getting a live video feed while the camera is submerged is another story. Wi-Fi and Bluetooth, which normally let you preview footage in real time, stop working underwater due to signal loss. So how do you actually see what your camera sees — live — while it’s underwater?

Whether you’re fishing, filming marine life, inspecting infrastructure, or live streaming an event, this guide walks through the best solutions for getting a real-time video feed from your action camera underwater — including Seavu’s tethered live-view kits using Wi-Fi/Bluetooth, and professional wired systems using DisplayPort over USB-C.

Live View with Wi-Fi/Bluetooth: Seeker & Explorer Kits

For compact, portable, and recreational applications, Seavu’s Seeker and Explorer Kits allow you to stream live underwater footage from your action camera to your phone or tablet using the camera’s native app.

How it works:

  • Your camera sits in a sealed housing and is connected to a built-in receiver (within the Seeker or Explorer unit).

  • A marine-grade tether cable carries the signal to the surface.

  • At the surface, a transmitter sends the feed to your mobile device.

  • You view the live footage via the standard GoPro or DJI app.

Key Benefits:

  • Lightweight and easy to deploy

  • Compatible with most action cameras (GoPro, DJI, etc.)

  • Lets you use your own phone or tablet as a screen

  • Ideal for fishing, exploring, marine research, and on-the-go filmmaking

This setup provides real-time underwater viewing using your camera’s built-in Wi-Fi and Bluetooth — with the tether cable acting as the vital link to maintain the connection.

Wired Video Output for Professional Feeds: DisplayPort Over USB-C

For critical applications that require uncompressed, high-quality live feeds, such as inspections, research, or live production, a wired solution using DisplayPort is the best option.

That’s where the DJI Action 5 Pro and Seavu Explorer+ Pro Kit come in.

DJI Action 5 Pro: The Only Action Camera with Built-In DisplayPort

The DJI Action 5 Pro is currently the only action camera that supports native DisplayPort output, making it the first of its kind to enable high-resolution, uncompressed video streaming directly to a monitor, TV, or capture card. When combined with the Seavu Explorer+ Pro Kit, this opens the door to professional-level underwater filming, live monitoring, and event production.

With DisplayPort and Power Delivery (PD) both handled via a single USB-C cable, this setup eliminates the need for battery swaps, wireless connectivity, or bulky external accessories.

GoPro doesn’t currently support DisplayPort or a single-cable solution for both video and power, making it less suitable for professional live underwater video.

This is such a huge feature, we can’t see GoPro leaving it out of future models for long.

Seavu Explorer+ Pro Kit: DisplayPort and Power via a Single USB-C Cable

The Explorer+ Pro Kit is the first underwater camera system designed to support both DisplayPort video and Power Delivery (PD) via a single USB-C cable — known as the Media Cable.

Key Features:

  • 15m fibre-reinforced USB-C Media Cable

  • DisplayPort output for uncompressed video to TVs, monitors, or capture cards

  • Power delivery keeps your DJI Action 5 Pro running continuously

  • No need for Wi-Fi, Bluetooth, or battery swaps

  • Rugged and marine-proof for real-world field conditions

This setup offers a direct connection between your camera and the screen, ensuring a stable, crystal-clear live feed every time.

Final Thoughts

Getting a live underwater video feed isn’t just for researchers or film crews anymore — and with Seavu, there’s a solution for every use case.

  • Want a simple, portable way to stream live to your phone? Go with the Seeker Starter Kit or Explorer Adventure Kit.

  • Need professional-grade footage streamed directly to a monitor? The Explorer+ Pro Kit with DJI Action 5 Pro is the world’s first system to deliver DisplayPort and power via a single USB-C cable.

Whatever your application, Seavu makes it possible to see beneath the surface in real time.
