Today I wanted to say something like

A camera whose wires go through the wall.

but it sounded funny. Whose to my ear only applies to people, and perhaps animals.

Is there a single word I can use in its place? I can say something like "A camera that has wires..." but I just wondered why another word didn't come readily to mind — or perhaps more accurately, I wondered why I wanted to use whose with the camera!

Bonus: what is the grammatical name for the word whose in this sentence? What part of speech is it?
