What to do with the answer, beyond the settings pages above: a pin that should be
known to *every* unit of a model belongs in that device's profile rather than being
re-entered on each camera. See

Once you know a board's numbers, put them where the camera will read them — on
**Settings → Pins** and **Settings → Day / Night** for one camera, or in a device
profile so every unit of the model comes up knowing them. Both routes:
