The Ubiquiti UniFi Cloud Key G2 is a controller that allows you to remotely control all your Ubiquiti UniFi access points. You can connect the Cloud Key to your network and set it up in a few minutes using Bluetooth and the app for your smartphone or tablet. You can then configure and monitor all your access points from a single overview. For example, you can see the number of connected devices and the amount of traffic on your WiFi network. The display on the Cloud Key itself shows you the most important information. The integrated battery ensures that you won't lose any data in case of a power outage.
