camera

note to self: sometimes it happens that applications cannot find a camera on my system, although it is definitely built in and not broken. This can be solved by stopping all applications that may be using the camera and then in a terminal run sudo killall VDCAssistant thanks to http://osxdaily.com/2013/12/27/fix-there-is-no-connected-camera-error-mac/ for this solution (check that link for further details)
