Aiphone AX-8MV Audio/Video Master Station

The Aiphone AX-8MV is a wall-mounted audio/video master station designed for multi-unit intercom and door communication systems. This device serves as a central control point for organizations requiring centralized monitoring and selective call routing across multiple master stations and door entry points.

Overview

The AX-8MV operates on PoE+ (802.3at) power delivered over Cat-5e cabling, eliminating the need for dedicated power supplies at the master station location. The system supports hands-free VOX (voice-operated exchange) or push-to-talk simplex communication modes, allowing flexibility in deployment scenarios. A 3.5-inch LCD screen provides visual feedback and monitoring capabilities. The unit features a compact wall-mount form factor suitable for office, residential, or institutional applications, with an optional adjustable desk mount available separately.

Key Features

• PoE+ Power: 802.3at power over Cat-5e cabling eliminates auxiliary power requirements at the master station
• 3.5-inch LCD Display: Color composite video output for door station monitoring and status indication
• Hands-Free and Push-to-Talk Modes: VOX-enabled communication or manual push-to-talk operation, selectable per installation requirement
• 8 Master Station Buttons: Dedicated call buttons for direct communication with up to 8 additional master stations on the same system
• 8 Door Buttons: Integrated buttons for addressing up to 8 door or sub-station units without external selector modules
• All Call Function: Broadcast capability to contact all master stations simultaneously
• Group Call Capability: Selective group calling to organized subsets of master stations
• Scan Monitoring: Automated sequential monitoring of connected door stations for real-time visual surveillance
• Extended Wire Distance: Compatible with Cat-5e runs up to 980 feet to the central exchange unit, accommodating large facility deployments
• Surface Mount Design: Installs directly to wall or desk surfaces; optional MCW-S/A adjustable desk angle mount available for custom positioning

Integration and Compatibility

The AX-8MV integrates with the Aiphone AX Series ecosystem, including audio master stations (AX-8M), door stations (audio and video variants), sub-stations with and without privacy features, and optional 16-door selector modules (AX-16SW) for expanded door addressing beyond the integrated 8-button configuration. All components communicate via Cat-5e cabling to a central AX Series exchange unit.

Typical Applications

The AX-8MV addresses multi-tenant buildings, office complexes, healthcare facilities, educational institutions, and secured access environments where centralized intercom control and visual door monitoring are required. The combination of up to 8 local master stations and 8 integrated door buttons makes the AX-8MV suitable for mid-sized deployments without requiring additional selector hardware.

I've evaluated the AX-8MV during planning phases for several mid-sized facility deployments. This master station positions itself as a straightforward centralized control point for multi-unit AX Series installations. The integrated 8 master + 8 door buttons eliminate the need for external selectors in smaller-to-medium configurations, which simplifies deployment planning and reduces component count at the master location.

Technical Highlights:

• PoE+ Efficiency: 802.3at power delivery via Cat-5e significantly reduces installation complexity compared to traditional power supply distribution, particularly across extended facility distances.
• Dual Communication Modes: VOX hands-free operation reduces user burden during routine calls, while push-to-talk simplex preserves explicit call control for security-sensitive environments.
• Extended Cabling Distance: 980-foot Cat-5e reach to the central exchange accommodates large buildings and campus-style deployments without requiring intermediate repeater equipment.

Deployment Considerations:

• PoE+ power availability must be confirmed at installation locations; verify switch or injector specifications match 802.3at output requirements.
• The 8-button configuration covers most mid-sized facilities, but confirm door count and master station count during design phase—exceeding either may require paired AX-16SW selector modules.
• LCD composite video output quality depends on door station video encoding and central exchange bandwidth; test video clarity during commissioning.

The AX-8MV delivers reliable multi-point intercom control without unnecessary complexity. It's a solid fit for facilities where direct button access to common endpoints (main lobby, emergency exits, department offices) is operationally important, and where the 980-foot Cat-5e reach aligns with your building infrastructure.
