The Ubiquiti UniFi CloudKey Plus SSD (UCK-G2-SSD), released in 2024 as an upgraded variant of the Gen2 Plus, is a fully integrated, stand-alone hybrid controller combining UniFi Network management for up to 50 devices/1,000 clients with UniFi Protect NVR capabilities via pre-installed 1TB SSD for faster, more reliable storage compared to HDD models.

It features an eight-core ARM Cortex-A57 processor @ 1.7 GHz and 3 GB DDR3 RAM for robust multi-app performance (Network, Protect, Talk, Access), with a 1.3" LCM color touchscreen displaying real-time stats like device health and storage usage. Measuring 131.2 x 27.1 x 134.2 mm and weighing ~320 g, its sleek black enclosure supports PoE (802.3af) via Gigabit Ethernet or optional USB-C (Quick Charge 2.0/3.0) for flexible powering (under 15W draw), enabling remote private cloud access via Ubiquiti SSO without third-party hosting.

Bluetooth LE simplifies initial setup via the UniFi mobile app, while hybrid cloud ensures secure, local data retention. Strengths include its all-in-one design for simplified deployments, SSD speed for quicker video scrubbing, and scalability, but it lacks built-in WiFi and requires SSD replacement with 5V-compatible drives—ideal for campus or remote site management without dedicated servers.
