Abstract: A removable hinge for connecting a plate to a bracket. The bracket has a hook slot which has an open end and a retaining end. A hook on the plate fits into the open end of the hook slot and slides along the hook slot to the retaining end. When the plate is in a hanging position, the hook is at the retaining end of the hook slot. The plate is removable from the bracket by sliding the hook from the hook slot out of the open end. The removable hinge may be advantageously use in coupling a camera assembly, such as a bullet camera, to a bracket mounted on a wall or ceiling.

Abstract: A swivel joint for an articulating arm comprising a section having a bore with an annular groove where the bore is sized for a stud, with another annular groove, of a plate to slide into the bore. A retaining ring seats in the annular grooves to swivelly couple the section with the plate. The arm may be advantageously used in a camera assembly, such as a bullet camera, to point the camera once mounted on a wall or ceiling.
