The Cloud Key enables the use of the management software without the hassle of installing on a dedicated PC. Just a shame it takes up a PoE port on their switch. recommended for managing multiple Ubiquti products. Used for a home network.
A great replacement for onsite ubiquity software no more dedicated PC and best of all cloud service is free. easy to remotely manage with ios app. took a bit of figuring out to enable others to create vouchers but i was looking too deep in to it! recommended if you have multiple sites. only downside is auto firmware upgrade doesn't work.
