Correct, the camera is built for an all sky survey. With the wide field of view it should be able to image the full night sky once every two or three days.
Yes, and to amplify, part of the utility is in its ability to observe transient phenomena. As we have been able to do more large-scale surveys, and scan the resulting images with transient detection software, we have observed a lot of surprises. LSST is designed to step that up by a lot.
