Compared to the previous generation, the new CloudKey G2 Plus is an entirely different animal. From a form factor perspective, the UCK-G2-PLUS looks like a tiny network switch with a glass front panel and ports on the back. The front panel is actually a screen that displays some status information, such as the current data throughput, the number of connected cameras, the time, IP address, etc.What's new is that instead of using Power-over-Ethernet, you can now use USB-C with QuickCharge to power your CloudKey. I'm using a regular PoE-enabled ethernet port with my CK, so I don't have to occupy another port on my uninterruptible power supply (UPS).Storage-wise, UC-CK had a small built-in storage unit and a microSD card slot to store its configuration data and UniFi controller software, among other things. UCK-G2-PLUS has a built-in 1 TB hard drive that you can upgrade to up to 5 TB.From a controller and software perspective, the new CloudKey includes not only the UniFi SDN network management software but also the UniFi Protect Video surveillance software. In other words, the new CK has inherited the capabilities the NVR used to provide.
