The UniFi Access G2 Starter Kit Pro in depth
Complete entry and exit control for one door
The UA-G2-SK-PRO bundles everything the record lists for managing a single door with two readers: one Door Hub, one G2 Reader Pro, one G2 Reader and two Pocket Keyfobs. The second reader can be used for door exit, or for entry on an additional door, although a second Hub is required for that additional door. The kit is managed through the UniFi Access application.
Door Hub
The Door Hub supports 1 door and a maximum of 6,000 users. It has (5) 10/100/1000 Base-T ports, a PoE++ input (50V DC, 1A) and (4) PoE outputs at 50V DC, 30W per port, with a maximum of 45W aggregated. Inputs cover door exit request, door position and emergency. Lock and auxiliary relays are provided as dry or powered outputs. The polycarbonate enclosure measures 174.9 x 126 x 32.9 mm, weighs 363 g and includes DIN-rail mounting.
G2 Reader Pro, G2 Reader and Pocket Keyfobs
The G2 Reader Pro has a 120 mm (4.7") portrait capacitive touch display, a proximity sensor, a 1.5W speaker, BLE 4.2 and NFC. The G2 Reader is a compact unit with BLE 4.1, NFC and a 0.7W speaker. Both readers are IP55-rated, use PoE, and have an NFC read range under 30 mm. The two Pocket Keyfobs are IP54-rated and support MIFARE DESFire EV3 4K.
