Whether you’re fishing, exploring reefs, inspecting marine structures, or capturing cinematic underwater scenes โ being able to livestream underwater footage in real time is a gamechanger. But action cameras alone canโt stream from beneath the surface. Water blocks wireless signals like Wi-Fi and Bluetooth, cutting off your live connection the moment your camera goes underwater.
Thatโs where Seavu comes in. In this guide, weโll show you exactly how to livestream underwater footage from your GoPro or DJI camera using Seavu kits โ either to your phone or tablet, or directly to a TV, monitor, or computer using DisplayPort.
Most action cameras today โ like the GoPro HERO13 and DJI Action 5 Pro โ come equipped with Wi-Fi and Bluetooth so you can control your camera or livestream to a mobile device. These connections are greatโฆ while the camera is above water.
But the moment your camera goes beneath the surface, the signal drops out. Thatโs because water absorbs high-frequency radio waves, especially the 2.4GHz and 5GHz bands used by Wi-Fi and Bluetooth. Even at shallow depths, wireless signals are blocked within seconds โ meaning you canโt view, control, or record live footage from your phone while the camera is underwater.

Seavu was created to bridge this communication gap.
Our camera systems use a marine-grade tether cable that carries your cameraโs wireless signal to the surface, where itโs picked up by a receiver and wireless transmitter. This lets your phone, tablet, or TV maintain a seamless connection to your camera โ even when it’s metres below the surface.
No signal loss. No delay. Just live footage โ straight from beneath the surface.
This is the go-to option for mobile users looking to view and control their camera while underwater. Ideal for:
Both kits:
Example: Snapper fishermen use the Seeker Kit to mount a camera to a burley pot and watch fish approach in real time on their phone โ giving them an edge when choosing the right lure and spot.
For more advanced applications, such as marine research, charter tours, or film production, you can use Seavu to livestream underwater footage directly to larger screens โ with zero compression and uninterrupted power.
Key Features:
Example: A reef tour operator mounts the Explorer+ Kit off the back of the boat and streams the underwater scene directly to a large TV onboard โ creating a captivating guest experience without anyone getting wet.

Unlike HDMI, DisplayPort over USB-C allows a single cable to transmit both uncompressed video and power. That means:
