Find your camera, tap the card, then scan the code with the StreamBridge app. Only one code opens at a time, so the camera in your hand can only ever see the one you chose. No signal where you are? Grab the PDF before you head out — it works offline.
Keep this link with the crew. Each code arms its camera for the live broadcast, so anyone who opens one can publish to the race feed. Share it with your operators rather than posting it publicly.
