Aiphone KMB-45 45-Degree Mullion Mounting Bracket

Overview

The Aiphone KMB-45 is a specialized mounting bracket engineered to install 1-gang surface mount door stations on glass doors with the camera positioned at a 45-degree angle. This geometry does two things simultaneously: it optimizes sightline coverage of entry points while routing wiring inside the door mullion — the vertical framing member that divides glass panes. The result is a clean, professional appearance where cable runs disappear into the frame structure rather than running exposed across the glass or trim.

This bracket is purpose-built for facilities where aesthetics and sightlines both matter — educational campuses, office lobbies, retail showrooms, and residential buildings with frameless or minimal-profile glass doors.

Key Features

• 45-Degree Mounting Angle: Positions the door station camera to cover entry passages and vestibules without pointing straight out perpendicular to the door. This angle reduces unwanted reflections from the glass and frames the facial capture zone more naturally than a flat-mount bracket would.
• Mullion-Integrated Wiring: The bracket design channels cables into the door mullion cavity, eliminating exposed runs along the glass surface. Matters in high-traffic or customer-facing areas where visible wiring undermines the installation aesthetic and can invite tampering or accidental damage.
• Left or Right Installation: Mounts to either side of the mullion, adapting to architectural layouts where the door swings one direction or the other. Gives integrators flexibility without requiring separate left-hand or right-hand SKUs.
• Compatible with Aiphone 1-Gang Surface Mount Stations: Works with Aiphone JP-DA and JP-DV models and all other 1-gang surface mount door stations in the series. Confirm your specific door station model before ordering to ensure mechanical fit.
• Minimal Footprint: The bracket itself is compact and does not add significant projection beyond the door frame. Important in tight vestibules or high-traffic corridors where protruding hardware can obstruct passage or become a safety hazard.
• Durable Mounting Hardware: Includes fastening components suited to glass and aluminum frame attachment. Verify that your door frame material (aluminum extrusion, PVC, stainless steel) is compatible with the supplied hardware before installation.

Deployment Considerations

The KMB-45 is a mounting accessory, not a standalone product. Success depends on three factors: (1) correct door station model, (2) mullion depth sufficient to route cabling without sharp bends, and (3) glass thickness and frame profile matching Aiphone's mechanical specifications. If your door uses a frameless design or has a mullion narrower than 1.5 inches, contact the door station manufacturer to verify fit.

For facilities managing multiple entry points, this bracket standardizes the installation approach — keeping camera angles consistent and appearance uniform across the building. Pairs naturally with a network video recorder and a structured access control system if intercom and surveillance are integrated.

When to Choose a Different Mounting Approach

If your entry points use solid wood or composite doors rather than glass, a standard surface-mount bracket or wall-mount plate will be simpler and more economical. If the mullion cavity is too shallow to route cables, or if aesthetic concealment is not a priority, a standard flat-mount bracket eliminates one variable from the installation. Always confirm mullion dimensions and door frame material before committing to the KMB-45.

Frequently Asked Questions

Q: Will the KMB-45 work with door stations other than Aiphone JP-DA and JP-DV?

A: The KMB-45 is designed for Aiphone 1-gang surface mount door stations. If you have a different brand or form factor, verify the mechanical mounting dimensions with the door station manufacturer before ordering.

Q: Can I install the KMB-45 on both sides of a double-glass entry door?

A: Yes, the bracket can mount on either the left or right mullion. For double-glass entries with center mullions, you would order one bracket per side if deploying dual door stations for coverage of both entry directions.

Q: What is the minimum mullion width required for cable routing?

A: Refer to Aiphone's installation documentation for the door station model you are using. Mullion depth typically needs to accommodate standard Ethernet and power cabling without sharp kinks. Narrow or solid framing may not support this bracket.

Q: Does the 45-degree angle affect the field of view of the camera?

A: The bracket angle is a mounting geometry — it does not change the camera's intrinsic lens field of view. However, the 45-degree installation angle will position that field of view at an oblique angle to the door plane, which can alter your coverage footprint in the entry vestibule. Test coverage before final deployment, especially in narrow corridors.

Q: Is the KMB-45 suitable for outdoor glass doors?

A: The bracket itself is mechanical and weather-tolerant, but verify that your Aiphone door station is rated for outdoor environment (IP rating, temperature range, UV resistance). The bracket does not add environmental protection — that responsibility rests with the door station enclosure.

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

The KMB-45 is a clean solution for a specific problem: mounting an IP door station on glass without visible cable runs. The 45-degree geometry is not arbitrary — it addresses two real constraints. First, it lets you hide Ethernet and power inside the mullion cavity. Second, it tilts the camera sightline away from the plane of the glass itself, which cuts down on reflections and improves facial capture when visitors walk toward or away from the entry rather than across it. If your facility has frameless glass or a mullion shallower than ~1.5 inches, this bracket won't work. But in a standard commercial glass entry with aluminum framing, the KMB-45 delivers the aesthetic integration that building managers and architects actually care about.

Technical Highlights:

• 45-Degree Mount Angle: Optimizes camera sightline for entry passage coverage and minimizes glass reflection interference — measurable improvement in facial image quality compared to flat perpendicular mounting on narrow or reflective glass.
• Mullion Cable Routing: Eliminates exposed runs across the glass surface, keeping the installation visually clean and reducing risk of cable damage in high-traffic areas. Requires verification of mullion depth and frame material compatibility before deployment.
• Reversible Left/Right Mounting: Single SKU adapts to either side of the mullion, reducing inventory overhead and simplifying standardization across multi-door facilities.

Deployment Considerations:

• Mullion cavity depth must accommodate standard Ethernet and power cabling routed without sharp bends. Verify this before ordering — a cable pinch inside the frame is a hidden failure risk.
• The bracket's mechanical design assumes standard aluminum or PVC frame profiles. Frameless, all-glass, or custom door systems may require custom fabrication or a different mounting strategy entirely.

The KMB-45 is the right choice for new-construction or major renovation projects where you're specifying both the glass door system and the security infrastructure in parallel. It positions your intercom and camera as integral to the entry aesthetic rather than as an afterthought. For retrofit installations on existing doors, measure your mullion first — if the cavity is too shallow or the frame material doesn't match Aiphone's mechanical spec, a surface-mount arm or a different bracket design will save you a re-do.
