When Neo and Morpheus go to see the Oracle, there is a shot where you see the doorknob, and Neo reaching for it. Pause it and look closely. Morpheus is further back and off to the right slightly, and the camera is in front of him. It is covered in the same material Morpheus' coat is made of, to hide it. But you can see the lens of the camera, the big black round thing in the center of the picture (off center on the doorknob).
