The Vaddio Drop Down Ceiling Mount for Large PTZ Cameras – Long is compatible with the Vaddio PRO & CCU HD1 PTZ camera systems as well as with the Polycom EagleEye & TANDBERG Precision HD cameras. It is made of heavy-gauge steel with a black powder coat finish that is both attractive and lasting. The mount consists of a mounting tube which extends approximately 24″ (0.6 m) below the ceiling. The mounting tube acts as a cable pass-thru for the Vaddio EZ Camera Cat. 5 cabling system. The large 5″ flange provides added stability.
