Ubiquiti UA-G3-SK-PRO UniFi Access Starter Kit

Overview

The Ubiquiti UA-G3-SK-PRO is a compact access control starter kit designed for single-door deployments requiring dual-reader capability. This kit provides a foundation for physical access management within UniFi ecosystems, supporting Apple's identity platform integration. The controller measures 84 x 39 x 7.4 mm and weighs just 16 grams, making it suitable for flush or surface mounting in confined spaces. Power delivery via PoE reduces infrastructure complexity, requiring only a single network run to the access point.

Key Features

The UA-G3-SK-PRO accommodates two credential readers on a single door using a polycarbonate and stainless steel enclosure rated IP54 for indoor and covered outdoor environments. The housing incorporates silicone rubber gaskets and an aluminum alloy mount to withstand temperature ranges from −10 to 45°C without performance degradation. A single 10/100 Mbps RJ45 port handles all network communication with a power budget of 5W at 48V DC, well within standard PoE++ allocations. ESD protection rated to ±15kV air discharge and ±8kV contact discharge protects against field-induced transients. The kit carries CE, FCC, IC, and UL 294 certifications, plus CAN/ULC-60839-11-1 compliance for Canadian installations and is NDAA-compliant for federal procurement scenarios.

Deployment Scenarios

Single-door access control is the primary use case—receptions, secure rooms, or facilities requiring credential verification at entry points. The dual-reader configuration supports multi-factor authentication workflows, such as badge and PIN, or simultaneous card and biometric readers. The compact form factor suits retrofit installations in existing door frames where space is constrained.

Network Integration

The Ubiquiti UA-G3-SK-PRO integrates with UniFi access management controllers over standard IP networks. PoE delivery simplifies cabling; a single Cat5e or Cat6 run provides both power and network connectivity. Apple identity platform support enables credential provisioning via device trust frameworks, reducing reliance on traditional card issuance workflows.

Installation Notes

Mount the controller using the included aluminum bracket in a location that permits reader access without obstruction. Verify PoE+ availability from the network switch (minimum 5W allocation). Confirm operating temperature stability; avoid direct sunlight or HVAC discharge that could exceed the 45°C maximum. MPN UA-G3-SK-PRO is the correct SKU for ordering this two-reader variant.

Karl Wilson, Infrastructure Engineer

"The UA-G3-SK-PRO fills a real gap for small-scale access deployments. Dual-reader support in a package this size is practical for labs, small offices, and branch facilities. PoE power keeps the bill of materials predictable, and NDAA compliance opens doors in government and defense sectors. I've deployed these on UniFi networks without complications; the ecosystem maturity shows. If you need single-door control without enterprise overhead, the UA-G3-SK-PRO delivers baseline functionality at a reasonable cost."
