Record your first take

This records video, motion data and audio to the camera's memory card, with no phone or computer involved.

  1. Insert a memory card. Use a V30 microSD card formatted as exFAT (recommended cards). Insert it before powering the camera.

  2. Remove the lens cap. Pull it straight off. Don't twist the lens — the focus is set at the factory.

  3. Connect power. Plug the USB-C cable into the camera and into a power bank or charger. The light turns white straight away while the camera starts up and processes recordings from earlier sessions (for example repairing a take after power was pulled mid-recording). This can take a little while. Don't unplug it — it turns green when done.
  4. Wait for green. A solid green light means ready.
    Status light solid green
    Green: ready.
  5. Press the button to record. Tap the button once. The light turns blue — you're recording.
    Status light solid blue
    Blue: recording.
  6. Press again to stop. The light turns white while the camera finishes saving the take, then green.

    Don't unplug while the light is white

    White means the take is still being written. Wait for green before removing power or the card.

  7. Copy your recording. Unplug the camera, take out the card and put it in a card reader. Your recordings are in the Trinet folder — see Files on the card.

What next?

  • Look at the data. The .imu and .vts files are binary; open them with the Python toolkit, which can also draw the motion data over the video.
  • Record for hours. Mono takes are saved automatically after 8 hours; Stereo takes have no limit. Check power and heat for long sessions.
  • Multiple cameras? A Wrist Kit starts and stops every camera together.
  • Something unexpected? See LED indications and Troubleshooting.

If power is lost mid-take

Don't worry. The next time the camera starts with that card, it repairs the interrupted take automatically (light shows white), losing at most the last second.
