US Patent 10078255 Camera surveillance assembly

A camera surveillance/inspection assembly and a unique coupling assembly are disclosed. The surveillance/inspection assembly includes a pair of selectively variable length rod members connected to each other by the selectively rotatable coupling. The coupling includes a pair of abutting rotatable members locked together by internal meshing annular toothed portions. The rotatable members and meshing toothed portions are selectively disengaged by depressing a spring urged connecting shaft. Rotation of either or both of the rotatable members will angularly orient the rod members with respect to each other.
