I ended up going with Ubiquity.
1 x Dream Machine
1 x Cloud Key
Some access points, a door bell and a bunch of G4 cameras.
Purchased direct from their store in the US. As even with the commercial account we have with PB Tech I was going to pay nearly $2000 more.
Only issue I had was that they limit the number of G4 dome cameras you can buy at once to 2. But then allow you to place a second order for them....
I didn't go for the server rack sized stuff in the end. Was going to take up too much space. And make getting it to NZ more difficult.
But the Dream machine has IDS/IPS throughput of 850mbps which is pretty damn good for a little device. My max connection speed is 900mbps anyway.
