Ubiquiti UA-HUB-DOOR-MINI vs Speco Technologies A1: Specification Comparison
Both the Ubiquiti UA-HUB-DOOR-MINI and the Speco Technologies A1 are single-door access control devices targeted at installers handling small-footprint deployments. The UA-HUB-DOOR-MINI is positioned as a PoE++-powered compact hub within the UniFi ecosystem, while the A1 is a standalone door controller with dual Wiegand reader support and onboard relay outputs. Buyers comparing the two are typically weighing ecosystem integration and wiring simplicity against standalone controller flexibility, reader topology, and relay-driven lock control in a conventional 12VDC architecture.

How does each unit handle power delivery and field wiring?
The UA-HUB-DOOR-MINI is powered entirely via PoE++ (802.3bt) at a rated 19W without PoE output, meaning a single Cat5e/Cat6 cable from a PoE++ switch delivers both data and power with no local power supply required. Its three GbE RJ45 ports provide network connectivity at the door. Physical dimensions are 113 × 66 × 27.6 mm with a 190 g polycarbonate/metal enclosure.
The Speco A1 requires a dedicated 12VDC @ 2A supply (not included in the package per specs), adding a line-voltage transformer or wall-wart to the installation bill of materials. The A1 provides two Form C relays rated 24V @ 1.0A, enabling direct control of electric strikes, maglocks, or auxiliary devices. Relay output capability is not specified for the UA-HUB-DOOR-MINI.
What reader interfaces and transaction throughput does each controller support?
The Speco A1 explicitly supports dual Wiegand readers per door — enabling simultaneous badge-in and badge-out tracking at a single portal — and is rated at 45+ transactions per second. On-board storage is 8GB eMMC, providing local credential and event buffering. Wiegand is the dominant legacy reader protocol across the installed base of card readers and keypads.
The UA-HUB-DOOR-MINI specifications provided do not state reader interface types (Wiegand, OSDP, or otherwise), transaction throughput, or local credential storage capacity. Buyers who require explicit dual-reader topology or a published transactions-per-second rating should note this absence before specifying the Ubiquiti unit; those details may exist in the full UniFi Access datasheet but are not present in the specs supplied here.
Which certifications, environmental ratings, and platform dependencies apply?
The UA-HUB-DOOR-MINI carries CE, FCC, IC, UL 294, and CAN/ULC-60839-11-1 certifications and is explicitly NDAA compliant — a procurement requirement for U.S. federal and many state/local government projects. It is rated for indoor use at 0–40°C and is a DIN rail-mounted component within the Ubiquiti UniFi Access ecosystem, meaning management depends on UniFi network and access control software infrastructure.
The Speco A1 is UL-294 ETL-listed and operates from 10°C to 35°C (50–95°F) — a narrower thermal band than the Ubiquiti unit. Its housing is described as a white box form factor. NDAA compliance status is not stated in the provided specs. The A1 does not appear to be tied to a proprietary cloud ecosystem based on available specs, though compatible management software is listed only as 'straightforward' without naming a specific platform.
Which should you choose: the UA-HUB-DOOR-MINI or the A1?
Our take: The UA-HUB-DOOR-MINI is the stronger choice when the deployment runs on Ubiquiti UniFi infrastructure, requires NDAA compliance, or prioritizes single-cable PoE++ installation with no local power supply. Key spec deltas: the UA-HUB-DOOR-MINI's PoE++ (802.3bt) at 19W eliminates the separate 12VDC @ 2A supply the A1 requires; the UA-HUB-DOOR-MINI operates to 40°C versus the A1's 35°C ceiling; and the UA-HUB-DOOR-MINI holds explicit NDAA compliance while the A1's status is unspecified. Conversely, the A1 is the stronger choice where Wiegand reader topology is mandatory: it explicitly supports dual Wiegand readers with 45+ transactions per second and two Form C relays rated 24V @ 1.0A — relay and reader interface specs not confirmed for the Ubiquiti unit. Specify the A1 for conventional 12VDC panel-based builds; specify the UA-HUB-DOOR-MINI for UniFi-native or government-regulated single-door PoE deployments.

Frequently Asked Questions
Which should you choose: the UA-HUB-DOOR-MINI or the A1?
The UA-HUB-DOOR-MINI is the stronger choice when the deployment runs on Ubiquiti UniFi infrastructure, requires NDAA compliance, or prioritizes single-cable PoE++ installation with no local power supply. Key spec deltas: the UA-HUB-DOOR-MINI's PoE++ (802.3bt) at 19W eliminates the separate 12VDC @ 2A supply the A1 requires; the UA-HUB-DOOR-MINI operates to 40°C versus the A1's 35°C ceiling; and the UA-HUB-DOOR-MINI holds explicit NDAA compliance while the A1's status is unspecified. Conversely, the A1 is the stronger choice where Wiegand reader topology is mandatory: it explicitly supports dual Wiegand readers with 45+ transactions per second and two Form C relays rated 24V @ 1.0A — relay and reader interface specs not confirmed for the Ubiquiti unit. Specify the A1 for conventional 12VDC panel-based builds; specify the UA-HUB-DOOR-MINI for UniFi-native or government-regulated single-door PoE deployments.
Does the UA-HUB-DOOR-MINI or the A1 support Wiegand card readers?
The Speco A1 explicitly supports dual Wiegand readers per door. The UA-HUB-DOOR-MINI specifications provided do not state Wiegand or any other reader interface type, so this cannot be confirmed from available data — consult the full Ubiquiti datasheet before specifying it in a Wiegand reader environment.
Which unit is better suited for a government or federal project requiring NDAA compliance?
The UA-HUB-DOOR-MINI is explicitly listed as NDAA compliant. The Speco A1's NDAA compliance status is not stated in the provided specifications, so it cannot be confirmed for projects with that procurement requirement.
Do I need a separate power supply for either controller?
The UA-HUB-DOOR-MINI is powered entirely over PoE++ (802.3bt) from a compatible switch — no separate power supply is required at the door. The Speco A1 requires an external 12VDC @ 2A power supply, which is not included per the stated package contents.
