Local mode

In local mode, all cameras are connected to a single host running the GUI. Camera settings are saved as config presets — named subfolders under orange_data/config/local/, each containing the cameras you want to load together.

Folder layout

For instance:

orange_data
├── config
│   ├── local
│   │   ├── 5cam
│   │   │   ├── 2002488.json
│   │   │   ├── 2002489.json

Above, 5cam and center_ceiling are two config presets. The GUI lets you pick a preset to load that set of cameras.

Camera config JSON

Each preset contains one JSON file per camera, named after the camera serial number (e.g. 2002488.json). See the example config in the orange repo.
