The camera inside my building is not for deterrence - the burglar is already inside at this point and will not be deterred. Either way, as you note, my stuff is gone. If their attention is drawn to an internal security camera by a light, then they may disable it or otherwise take extra steps to conceal themselves or avoid the camera. If they do not notice the camera, I may get better/more footage for identification purposes.
