Axis P55-E Screw Kit for Wall Mounts - 5901-391

Axis 5901-391 Screw Kit for T91G61/T91L61 Wall Mounts

The Axis 5901-391 is a purpose-built fastening kit designed to mount AXIS P55-E Series pan-tilt-zoom cameras onto AXIS T91G61 or T91L61 wall mount brackets. This is a straightforward hardware accessory — no electronics, no firmware updates — just the mechanical components you need to complete a wall-mounted PTZ installation.

Key Features

• Bayonet screws (qty 3): Provide the primary mechanical coupling between camera and mount head. The bayonet design allows quick connect/disconnect during installation without full disassembly.
• Securing screws (qty 3): Lock the bayonet screws in place after camera alignment, preventing accidental rotation or vibration-induced loosening during pan-tilt operation or extended outdoor exposure.
• Springs (qty 3): Absorb minor vibration and thermal expansion cycles, reducing mechanical fatigue on the screw threads and camera mounting points — important for 24/7 pan-tilt duty in variable weather.
• Precision fit for P55-E Series: Hardware is engineered to match the exact mounting interface of AXIS P55-E cameras, eliminating over-tightening or cross-threading risk.
• T91G61 and T91L61 compatibility: Works with both AXIS wall mount models, covering a range of mounting heights and reach distances.

Integration & Compatibility

This kit is a direct replacement or initial supply for integrating AXIS P55-E Series PTZ cameras into wall-mounted surveillance systems. It is compatible exclusively with AXIS T91G61 (wall mount for smaller spaces) and AXIS T91L61 (wall mount with extended reach). Do not attempt to use this kit with other AXIS PTZ models or non-AXIS mount systems — the bayonet and screw thread geometry is specific to the P55-E interface.

When deploying PTZ cameras on wall mounts, this hardware ensures vibration damping and secure coupling critical for sharp pan-tilt imaging over extended operational life. For guidance on mount selection and installation planning, consult the PTZ camera selection guide.

Frequently Asked Questions

Q: Will the 5901-391 work with AXIS P55 Series cameras other than the P55-E?

A: No. The 5901-391 (often searched as 5901 391) is engineered specifically for the P55-E Series mounting interface. Other P55 variants may require different hardware.

Q: Can I reuse the springs and screws from an older AXIS wall mount installation?

A: Not recommended. Hardware wear, corrosion, or loss of spring tension reduces mount stability over time. A fresh kit ensures consistent performance across a multi-camera deployment.

Q: Do I need any tools beyond a standard screwdriver to install this kit?

A: The bayonet design is hand-aligned; a Phillips or hex screwdriver (size per the mount's documentation) is sufficient for the securing screws. No special tools required.

Q: What happens if I overtighten the securing screws?

A: Over-tightening can damage the camera's threaded mounting holes or compress the springs, reducing vibration absorption. Hand-tight plus a quarter-turn is the standard practice.

Q: Are replacement springs available separately?

A: The 5901-391 includes three springs as a complete set. If a single spring fails due to corrosion or fatigue, contact AXIS support or a qualified integrator for individual replacement options.

Q: Can I use this kit on indoor wall mounts as well as outdoor?

A: Yes. The fastening hardware is agnostic to environment; however, outdoor P55-E deployments on T91G61/T91L61 mounts will benefit more from the vibration-damping springs due to wind load and temperature cycling.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The Axis 5901-391 is not glamorous, but it's non-negotiable for a reliable P55-E wall mount. The inclusion of springs—three of them—is the key engineering detail here. On a PTZ camera doing continuous pan-tilt duty, especially outdoors, vibration and thermal cycling fatigue mounting hardware fast. Those springs take the micro-shocks and wobble out of the equation.

Technical Highlights:

• Bayonet coupling (qty 3): Speeds installation and reduces over-tightening risk compared to screw-only systems. Critical when deploying multiple PTZ cameras and every hour of labor counts.
• Spring-damping design: Absorbs vibration from pan-tilt motors and wind load, extending screw fastener life by reducing cyclic stress. Especially important in outdoor retail or warehouse environments with traffic or weather exposure.
• Precision thread geometry for P55-E: No cross-threading, no stripped holes. Means you deploy faster and don't lose cameras to hardware failure mid-project.

Deployment Considerations:

• Do not mix this kit with P55 models earlier than the E-series—mounting geometry is different and will result in loose camera head or stripped holes.
• Springs can corrode in marine or high-salt-air environments; inspect annually if deployed near coast or caustic industrial sites.
• The securing screws must not be overtightened; hand-tight plus one quarter-turn is the rule. Overtightening compresses the springs and can crack the camera's aluminum mounting bracket.

If you're installing P55-E cameras on T91G61 or T91L61 wall mounts—especially in outdoor retail, warehouse, or traffic monitoring—this is your hardware. Buy it. Use it correctly. It's the difference between a two-year mount life and a five-year one.
