Within the UniFi Access platform of Ubiquiti Inc., there are multiple controllers that each have a specific role in access management. The three most commonly used models are:
- UA-Hub-Door-Mini
- UA-Door-Hub
- UA-Gate-Hub
Although they are similar, they differ greatly in capacity, I/O capabilities and applications. In this article, we will explain which hub you need for your situation.
Overview of the three hubs
UA-Hub-Door-Mini
The Door Hub Mini is the compact entry solution for one door. It is ideal for simple installations such as homes, small offices or lockers.
UA-Door-Hub
The Door Hub standard offers more I/O, more flexibility and better expansion possibilities. This model is intended for professional single-door installations with additional sensors and accessories.
UA-Gate-Hub
The Gate Hub is specially designed for gates, garage doors and vehicle entrances. It supports advanced features such as LPR (License Plate Recognition) and multiple gate types.
Key Differences
1. Application (door vs gate)
- Door Hub Mini: 1 simple door
- Door Hub: 1 door with extended I/O
