Seems like my MacBook Pro's camera isn't working in High Sierra. Just testet in Sierra / macOS 10.12 on the same hardware and it's working fine there.
Under System Report > Hardware > Camera I can see the Model ID & Unique ID on High Sierra just fine as well.
When I launch Photo Booth or FaceTime apps the green light next to the camera doesn't turn on and booth apps just show a black screen. FaceTime.app even gives me the following error:
No Video
FaceTime has not received any video from the connected camera. Restarting your computer may fix this issue.
Multiple restarts have not resolved this issue. Has anyone else run into the same issue?
MacBook Pro (Retina, 15-inch, Early 2013)
