Ubiquiti UA-G3-SK-PRO vs Ubiquiti UA-HUB-DOOR-MINI: Specification Comparison
The UA-G3-SK-PRO and UA-HUB-DOOR-MINI are both Ubiquiti UniFi single-door access control hubs powered via PoE++, making them direct cross-shop candidates for installers specifying a one-door controller. The comparison centers on three axes that drive purchasing decisions in this product class: included reader hardware and door-control capability, physical form factor and environmental resilience, and power budget with certification compliance. Neither unit supports multi-door expansion; both are NDAA-compliant and sit within the UniFi Access ecosystem.

Which hub delivers more complete reader and door-control capability out of the box?
The UA-G3-SK-PRO ships as a kit: the Door Hub plus one G3 Reader Pro, one G3 Reader, and two Pocket Keyfobs. Its spec explicitly supports two readers on one door, enabling badge-plus-PIN or NFC multi-factor authentication at a single entry point. NFC compatibility covers Forum tags T1T, T2T, T3T, T4T, and T5T, and the hub also lists microphone support. The package contents confirm a turnkey single-door deployment with readers included.
The UA-HUB-DOOR-MINI ships as the hub only — no readers, no credentials. Its package contents list solely the UA-HUB-DOOR-MINI unit. The spec does not enumerate NFC tag compatibility, reader port count beyond the three GbE RJ45 ports, or audio support. Buyers must source and add readers separately. For integrators who already own or prefer specific third-party readers, this is not a drawback; for those wanting a ready-to-install kit, the PRO bundle is the faster path.
Which unit is better suited to harsh or outdoor-adjacent installation environments?
The UA-G3-SK-PRO uses a polycarbonate enclosure with an aluminum alloy mount and carries an IP54 ingress-protection rating, making it resistant to dust and splash. Its operating temperature range is −10 to 45 °C (14 to 113 °F), and ESD protection is rated at Air ±15 kV / Contact ±8 kV. Dimensions are 174.9 × 126 × 32.9 mm and weight is 363 g (12.8 oz). The spec lists surface mount as the mount type, with DIN-rail also noted.
The UA-HUB-DOOR-MINI is specified for indoor use only — the spec explicitly states 'Environment Rating: Indoor' with no IP rating listed. Its operating temperature range is narrower at 0 to 40 °C, excluding sub-freezing conditions. The enclosure is polycarbonate and metal. At 113 × 66 × 27.6 mm and 190 g (6.7 oz), it is physically smaller and lighter, purpose-built for IDF closets and wall-mounted cable trays via DIN rail. No ESD protection value is provided in the available spec data.
How do the two hubs compare on power draw, network connectivity, and regulatory certifications?
The UA-G3-SK-PRO draws 5 W at 48 V DC via PoE++ (802.3bt). Its network interface is listed as 10/100 Mbps RJ45 in one spec field, though a separate field notes Gigabit speed — installers should verify against the manufacturer datasheet at /content/product-datasheets/UA-G3-SK-PRO.pdf. Certifications include CE, FCC, IC, UL 294, CAN/ULC-60839-11-1, and NDAA compliance.
The UA-HUB-DOOR-MINI draws 19 W without PoE output, also via PoE++ (802.3bt). It provides three GbE RJ45 ports, suggesting downstream device connectivity. Certifications are CE, FCC, IC, UL 294, and CAN/ULC-60839-11-1; NDAA compliance is also confirmed. The MINI's higher baseline power draw (19 W vs. 5 W) is a meaningful factor when budgeting switch port wattage, particularly in high-density deployments. Neither unit lists a maximum PoE output budget to downstream devices in the provided specs.
Which should you choose: the UA-G3-SK-PRO or the UA-HUB-DOOR-MINI?
Our take: The UA-G3-SK-PRO is the stronger choice when a turnkey, environmentally resilient single-door deployment is required. Three concrete spec deltas drive that conclusion: first, the PRO ships with two readers and two keyfobs included, while the MINI ships as a hub only; second, the PRO carries an IP54 rating and a −10 to 45 °C operating range versus the MINI's indoor-only designation and narrower 0 to 40 °C range; third, the PRO adds ±15 kV ESD protection, which the MINI's spec does not list. Conversely, the UA-HUB-DOOR-MINI is the correct selection when readers are already on hand, the installation is a climate-controlled indoor space such as an IDF closet, and a compact DIN-rail footprint (113 × 66 × 27.6 mm, 190 g) is a priority. Its three GbE ports also provide more downstream wiring flexibility. Both units are NDAA-compliant and certified to UL 294 within the UniFi Access platform.

Frequently Asked Questions
Which should you choose: the UA-G3-SK-PRO or the UA-HUB-DOOR-MINI?
The UA-G3-SK-PRO is the stronger choice when a turnkey, environmentally resilient single-door deployment is required. Three concrete spec deltas drive that conclusion: first, the PRO ships with two readers and two keyfobs included, while the MINI ships as a hub only; second, the PRO carries an IP54 rating and a −10 to 45 °C operating range versus the MINI's indoor-only designation and narrower 0 to 40 °C range; third, the PRO adds ±15 kV ESD protection, which the MINI's spec does not list. Conversely, the UA-HUB-DOOR-MINI is the correct selection when readers are already on hand, the installation is a climate-controlled indoor space such as an IDF closet, and a compact DIN-rail footprint (113 × 66 × 27.6 mm, 190 g) is a priority. Its three GbE ports also provide more downstream wiring flexibility. Both units are NDAA-compliant and certified to UL 294 within the UniFi Access platform.
Do I need to buy readers separately for either hub?
Yes for the UA-HUB-DOOR-MINI — its package contents list only the hub unit. No for the UA-G3-SK-PRO kit (SKU UA-G3-SK-PRO), which includes one G3 Reader Pro, one G3 Reader, and two Pocket Keyfobs in the box.
Can the UA-HUB-DOOR-MINI be installed in an outdoor electrical enclosure or an unconditioned space?
Based on the provided specs, no. The UA-HUB-DOOR-MINI is rated for indoor use only with a 0 to 40 °C operating range and no listed IP rating. The UA-G3-SK-PRO carries an IP54 rating and operates from −10 to 45 °C, making it the appropriate choice for installations near exterior doors or in spaces subject to temperature extremes or splash.
Which hub places a lower demand on the PoE switch budget?
The UA-G3-SK-PRO draws 5 W at 48 V DC PoE++. The UA-HUB-DOOR-MINI draws 19 W (without PoE output) via PoE++. If switch port wattage is constrained — for example in a high-door-count IDF with a fixed PoE budget — the PRO's 5 W draw is significantly more efficient per port.
