Select how the dashboard reads your live ESP32 / Arduino node over the network. Use the endpoint URL printed on the node's serial monitor. Demo needs no hardware — it generates simulated cave readings so you can see the console working.
Leave blank if you have no camera. The ESP32-CAM prints this on its serial monitor — usually port :81/stream. If the dashboard is opened over https and the camera is http, allow "insecure content" for this site (Chrome) or run the dashboard locally.
