The outdoor and indoor, AXIS T91B51 Ceiling Mount is ideal where a PTZ dome or a fixed dome camera needs to be installed in low ceilings or in roof overhangs. If a longer length is needed, two optional extension pipes are available, 30 cm (12 in) and 100 cm (39 in). The ceiling mount is designed to swing and not break if hit by forklifts or tall vehicles. It can also be installed in sloped ceilings thanks to the ball joint, which ensures that the camera is still hanging straight.
