Axis 5507-461 Accessory mounting T91B51 ceiling mount content_copy

The AXIS T91B51 is a ceiling mount for installing PTZ dome and fixed dome cameras in indoor and outdoor environments. It is specifically designed for installations on low ceilings or in roof overhangs and allows flexible adaptation to different environments. The mount features a ball joint that always aligns the camera vertically, even on inclined ceilings up to an angle of ±45°. This ensures optimal viewing axis and secure mounting in sloped roof structures or flat roof constructions.

Applications
The AXIS T91B51 is particularly suitable for areas with limited ceiling height, such as parking garages, warehouse halls, or building entrances. The robust construction enables secure installation in indoor and outdoor environments, with the mount remaining intact even under mechanical stress, for example, from collisions with forklifts or high vehicles. The integrated swivel mechanism ensures that the mount yields upon impact and then returns to its original position, minimizing damage to the camera or the mount.

Features and Equipment in Detail
The mount is designed for cameras with 3,8 cm ( 1,5 inch )-NPS thread, enabling universal compatibility with various Axis camera models. The standard length of the mount can be extended using optional extension tubes in lengths of 30 cm or 100 cm, achieving a maximum total length of up to 5 m. This flexibility allows precise adaptation to the specific mounting situation, positioning the camera optimally.

Technology Explained Simply
The ball joint of the mount ensures that the camera always hangs vertically, regardless of the ceiling inclination. This is particularly important to ensure correct image alignment, especially in sloped roof structures. The swivel mechanism is a mechanical safety feature that allows the mount to flexibly yield upon impact without structural damage. This protects the camera from direct mechanical forces and keeps the mount functional.

Compatibility and Accessories
The AXIS T91B51 is compatible with all Axis accessory kits featuring a 3,8 cm ( 1,5 inch )-NPS thread, as well as with the AXIS T91A05 camera mount for fixed cameras. The extension tubes in lengths of 30 cm and 100 cm are available as separate accessories and can be combined as needed to achieve the required mounting length.

Installation and Mounting
Mounting is done to the ceiling, with the mount secured to the ceiling structure via the ball joint. The swivel mechanism allows easy adjustment of the camera to the desired position. Installation requires no special tools or additional mounting components beyond those already integrated into the mount. The mount is designed for ceiling mounting, as specified in the technical features.

Operational Advantages
The AXIS T91B51 provides stable and secure mounting for surveillance cameras in sensitive areas. The integrated swivel mechanism reduces the risk of damage from mechanical impacts, extending the lifespan of both the camera and the mount. The flexibility in length adjustment enables precise camera positioning, regardless of ceiling height or room architecture. Compatibility with various Axis camera models and accessory kits increases versatility and simplifies integration into existing surveillance systems.
