Ubiquiti UA-G3-PRO-W vs Axis A4612: Specification Comparison
Both the Ubiquiti UA-G3-PRO-W and the Axis A4612 are PoE-powered network access control readers designed for single-door credential verification in enterprise and commercial settings. The UA-G3-PRO-W is a wall-mount NFC reader operating within the UniFi ecosystem, while the A4612 is a mullion-mount reader supporting dual Bluetooth mobile credentials and RFID cards over an IP-based architecture. Buyers evaluating either unit are comparing credential technology, physical form factor, environmental suitability, management platform, and certification pedigree before committing to a door-control solution.

Which credential technologies does each reader support, and how does that affect deployment flexibility?
The UA-G3-PRO-W reads NFC credentials conforming to ISO/IEC 14443 Type A/B, covering standard proximity cards, keyfobs, and mobile NFC credentials presented by compatible smartphones. NFC requires the credential device to be held within a few centimeters of the reader face.
The Axis A4612 supports two distinct wireless technologies simultaneously: Bluetooth Low Energy for mobile credentials and RFID for physical cards. Bluetooth enables hands-free or long-range tap-to-unlock workflows where the mobile device does not need to touch the reader. The A4612's dual-technology support means a site can issue physical RFID cards alongside a mobile credential programme without deploying a second reader head.
For installations where the cardholder population is entirely card- or badge-based, the UA-G3-PRO-W's NFC coverage is sufficient. Where mobile-first or mixed credential environments are required, the A4612's Bluetooth+RFID stack provides broader native support without add-on hardware.
How do form factor, mounting style, and environmental ratings compare for real-world door hardware?
The UA-G3-PRO-W is specified as a wall-mount terminal with a polycarbonate and glass enclosure. It ships with a gang-box mount included and carries dimensions of 160 mm × 40.4 mm × 40.55 mm at 0.300 lb. Its operating temperature is documented as −10 to 45 °C (14 to 113 °F), and it is rated for both indoor and outdoor use.
The Axis A4612 uses a mullion-mount form factor, designed to fit the narrow vertical stile of a door frame rather than a flat wall surface. Axis specifies it as weather-resistant and rated for indoor and outdoor environments. Specific ingress-protection (IP) rating, operating temperature range, and physical dimensions are not provided in the supplied specifications.
The choice between these profiles is often dictated by door hardware: gang-box cutouts suit the UA-G3-PRO-W's wall-mount body, while narrow mullion frames suit the A4612. Installers should confirm rough-in dimensions and conduit locations before selecting either unit, as the two form factors are generally not interchangeable on the same rough-in.
What are the power requirements, management platforms, and certification levels for each reader?
Both readers are powered by PoE at 802.3af. The UA-G3-PRO-W draws a specified 6 W at 48 V DC through a single GbE RJ45 port, enabling a single cable run for both data and power. The A4612's PoE power draw is not specified in the provided data.
Management for the UA-G3-PRO-W is handled exclusively through the Ubiquiti UniFi Management Console, meaning credential management, door scheduling, and event logging are bound to the UniFi Access ecosystem. The A4612 operates over an IP-based architecture but the specific access-control management software or VMS integration is not enumerated in the supplied specifications.
On certifications, the UA-G3-PRO-W carries CE, FCC, IC, UL 294, and CAN/ULC-60839-11-1 listings. UL 294 is the North American standard specifically for access control units, and CAN/ULC-60839-11-1 extends that listing to the Canadian market. The A4612's certifications are not listed in the provided specifications. The UA-G3-PRO-W also carries an NDAA compliance designation per the supplied specs; the A4612's NDAA status is not stated. The A4612 is backed by a documented 5-year warranty; the UA-G3-PRO-W lists only 'Manufacturer Warranty' without a stated term.
Which should you choose: the UA-G3-PRO-W or the A4612?
Our take: The UA-G3-PRO-W is the stronger choice when the deployment is UniFi-native, requires UL 294 or CAN/ULC-60839-11-1 certification documentation, or must satisfy NDAA compliance requirements—none of which are confirmed in the A4612's provided specifications. Conversely, the Axis A4612 is the stronger choice when the door hardware demands a mullion-mount profile or when the credential strategy requires dual Bluetooth mobile and RFID support on a single reader head, a capability the UA-G3-PRO-W does not list. Key spec deltas: the UA-G3-PRO-W draws a confirmed 6 W over 802.3af and states an operating range of −10 to 45 °C, while neither figure is provided for the A4612. The A4612 carries a stated 5-year warranty versus an unspecified term for the UA-G3-PRO-W. Platform lock-in is the decisive qualifier: the UA-G3-PRO-W is tied to UniFi Access; the A4612's management ecosystem is not detailed in the available specifications.

Frequently Asked Questions
Which should you choose: the UA-G3-PRO-W or the A4612?
The UA-G3-PRO-W is the stronger choice when the deployment is UniFi-native, requires UL 294 or CAN/ULC-60839-11-1 certification documentation, or must satisfy NDAA compliance requirements—none of which are confirmed in the A4612's provided specifications. Conversely, the Axis A4612 is the stronger choice when the door hardware demands a mullion-mount profile or when the credential strategy requires dual Bluetooth mobile and RFID support on a single reader head, a capability the UA-G3-PRO-W does not list. Key spec deltas: the UA-G3-PRO-W draws a confirmed 6 W over 802.3af and states an operating range of −10 to 45 °C, while neither figure is provided for the A4612. The A4612 carries a stated 5-year warranty versus an unspecified term for the UA-G3-PRO-W. Platform lock-in is the decisive qualifier: the UA-G3-PRO-W is tied to UniFi Access; the A4612's management ecosystem is not detailed in the available specifications.
Can the UA-G3-PRO-W or A4612 read mobile credentials from a smartphone?
The UA-G3-PRO-W supports NFC-based mobile credentials (ISO/IEC 14443 Type A/B), which requires the phone to be held close to the reader. The A4612 supports Bluetooth mobile credentials, which can enable longer-range or hands-free unlocking, in addition to physical RFID cards. If Bluetooth mobile credentials are a requirement, only the A4612 lists that capability in the provided specifications.
Which reader is better suited for outdoor installation?
Both units are rated for outdoor use in the provided specifications. The UA-G3-PRO-W adds a confirmed operating temperature range of −10 to 45 °C and specifies a polycarbonate and glass enclosure. The Axis A4612 is described as weather-resistant but does not provide an IP rating, temperature range, or enclosure material in the supplied data. Installers should request the full Axis environmental datasheet before specifying the A4612 in harsh outdoor conditions.
Does either reader require a separate power supply at the door?
Neither reader requires a separate power supply at the door. Both the UA-G3-PRO-W and the A4612 are powered by PoE (802.3af), meaning a single Ethernet cable from a PoE switch or injector delivers both data and power. The UA-G3-PRO-W specifies 6 W consumption at 48 V DC; the A4612's exact wattage is not stated in the provided specifications.
