The invention provides a camera assembly which includes a housing having a mounting cap attached to sidewalls to which is attached an optical surface, the camera housing enclosing a camera system wherein the optical surface is rotatable relative to the camera housing after the camera system is positioned. Preferably, the optical surface is a dome rotatable relative to the housing through the use of a circumferential seal attached to a circumferential flange portion of the housing. Most preferably, the seal is a continuous, circumferential bi-level seal that is S-shaped in cross-section, said seal having a first level that includes a first groove that contains a circumferential flange portion of a wall portion of said housing, and a second level that includes a second groove that contains a circumferential flange portion of a wall of said dome.
