The PMAX-1400 from ACTi is a Mount for Dome Cameras Designed for mounting dome cameras from high ceilings. As opposed to an in-ceiling mount, this mount allows cameras to be suspended from the ceiling at a more convenient height for your surveillance needs. The mount is compatible with the ACTi D5X, D9X, E5X, E9X, E9XX, and E9XXM dome cameras and must be used in conjunction with a converter ring or compatible tube.
