I have been running the Unifi software for the wifi and cameras on my server, which works ok, but recording the 4 cameras was putting a lot of strain on the hard disks. A while a go Ubiquiti released the new cloud key, but the rack mount was always out of stock. I managed to get one off eBay and today i got it installed and configured. The new cloudkey has a 1tb hard disk that is used to record the cameras so that takes the load from my server. Overall its a great product, but i do think that the rack mount was slightly expensive for what it is.
