[TN] Is it legal for me to place a camera in my dorm; only looking at my computer with the consent of my roommate?

I was the victim of dorm vandalism. A woman my ex roommate was having sexual encounters with came back for revenge on him by pouring gallons of water in his electronics, and mine so It wouldn’t looked targeted at just him.

After a lengthy investigation I was not compensated or received justice, because there wasn’t physical evidence of someone specific or identifiable vandalizing my previous computer build. There aren’t ANY cameras in the hallways of the dorm nor in the stairwell. Only one camera in the lobby and it’s not for us. It’s so coca cola can protect their vending machines. This school doesn’t care our security.

So here I am, recently built a new computer and don’t want to sink thousands of dollars again to build another if someone vandalizes it.

So reddit, Is it legal for me to place a camera that’s only facing my computer in my dorm room with the consent of my new roommate?
