EGO1
EGO1 (model EGO1-HS, the GI EGO Headset) is a head-mounted stereo (binocular) egocentric capture device. Two forward-facing 1080p cameras at human eye spacing produce a clean stereo first-person stream, and an integrated 9-DoF IMU tracks head pose. It records offline to a MicroSD card and pairs over Wi-Fi for live preview.
It's designed to be operated with nothing more than an Android phone (the Visio Companion app, for live preview and control) and a computer with any MCAP viewer (for reviewing recordings).

How a session works
Insert SD card ─► Plug in USB power ─► Record ─► Stop ─► Offload ─► Review
(LED on) (always-on (app, or (SD card) (MCAP viewer)
or app) power off)
- Insert a MicroSD card and power the device from any USB source. The top LED lights up.
- Record — capture is always-on (it starts when the device powers on) or app-controlled (start/stop in the Visio Companion app). EGO1 has no physical record button.
- Optionally connect the Visio Companion app over Wi-Fi for live preview and control.
- Offload your recordings by pulling the MicroSD card, then open the
.mcapfiles in any MCAP viewer (for example, Foxglove Studio).
Use Wi-Fi (the app) to preview the device live. Get your recordings off the device via the MicroSD card — Wi-Fi isn't the recommended path for transferring recorded files.
If you're using app control, stop the recording and let it finish saving before unplugging USB power. In always-on mode, avoid cutting power during an active capture — a clip still being written can be lost.
