Overview
The Ubiquiti UA-G2-SK is a UniFi Access G2 Starter Kit designed to manage a single door with one reader. The kit combines the UA-Hub-Door controller with a UA-G2 proximity reader for a complete door-access deployment.
Access Control Hardware
The UA-Hub-Door provides five 10/100/1000 Base-T Ethernet ports and operates from PoE++. It provides four PoE passthrough outputs with a combined 20W budget, along with dedicated door-control inputs and relays for connecting a lock, auxiliary device, request-to-exit input, remote release, and door-position sensor.
The included UA-G2 reader connects through PoE and uses a 10/100 MbE RJ45 interface with BLE 4.1. Its 13.56 MHz NFC interface supports ISO 14443A, ISO 14443B, and ISO 15693 standards along with multiple NFC and MIFARE technologies.
Door Control and Power
The UA-Hub-Door accepts a 50V DC PoE++ input and can provide up to 20W of PoE passthrough across four outputs. Its dry-contact relays support up to 30V DC at 1A for lock and auxiliary control, while powered outputs provide 12V DC for compatible door-access hardware.
Reader Connectivity
The UA-G2 reader supports PoE power at 48V DC and consumes up to 5W. The reader provides NFC credential reading with a specified read range of less than 30 mm and includes proximity sensing, status LEDs, a speaker, and a factory-reset button.
Key Features
- Single-door UniFi Access starter kit with one G2 reader
- UA-Hub-Door with five Gigabit Ethernet ports and PoE++ input
- Four PoE passthrough outputs with 20W total output power
- 13.56 MHz NFC reader supporting ISO and MIFARE technologies
- Door lock, auxiliary, exit request, remote release, and door-position connections
Applications
The UA-G2-SK is designed for single-door access-control installations in offices, commercial buildings, controlled entrances, and other locations using UniFi Access. The hub provides the door-control interfaces while the included reader handles credential presentation.
DC Supplies Product Note
The UA-G2-SK is a single-reader kit. Its UA-Hub-Door provides the additional door-control interfaces and PoE passthrough required for a complete single-door deployment, while the UA-G2 reader is designed for indoor or outdoor installation.
