How is Fing app able to map a device to its Make and model number?

I use fing app on iPhone. I have an up camera from Samsung. Fing app is able to discover and tell me its model number SAMSUNG-SNH-P6410BN-MAC.

I would like to ask if anyone can suggest how is Fing app finding a model number of a camera. Rest of it is understandable but SNH-P6410BN is a specific model number of the camera.
