+Camera presets use `v4l2-ctl` from `v4l-utils` on the robot side.

 Role mapping:
 
 - `start-backend.sh` uses the `CONTROL_SIDE_*` address pair
 - `start-b-side-omnid.sh` uses the `ROBOT_SIDE_*` address pair
+- `start-b-side-omnid.sh` also applies the `OMNI_CAMERA_*` preset before the daemon opens the camera
 - `start-ros-receiver.sh` defaults to the robot-side address pair, but with `transport=unix_dgram` it usually does not need the server address
