A surface mount plate may include a plate having attachment mounting points that allow fasteners to secure the surface mount plate to a surface such that the surface mount plate is mounted in a fixed position on the surface. The surface mount plate may include a circular lip extending around at least a portion of the plate, the circular lip having distributed lip gaps. A sensor housing may include multiple sliders that couple with the circular lip of the surface mount plate when the sliders are aligned and inserted into the plurality of distributed lip gaps of the circular lip and the sensor housing is rotated. The sliders may slide along the lip to allow the housing to be rotated while the sensor housing remains coupled with the surface mount plate.
