You've got a G6 PTZ and you want it in the ceiling, not on a bracket jutting out over your carport or entryway. This black in-ceiling mount drops the camera into the ceiling cavity so only the lens ring is visible from below. Weatherproof rating means it handles exposed outdoor spots – think covered alfresco, a verandah ceiling, or a garage entry where rain and sun hit it daily. No bracket shadow on the wall behind it. Just a clean black ring in the ceiling and full pan-tilt-zoom range. Fits both the black and white G6 PTZ bodies. One plate, one recess, sorted
