I read something recently that someone hacked into a casino IT system via a wifi fish tank accessory...could be complete nonsense but it got me thinking whether I should split our network for security with the wireless devices? Is it worth setting up separate networks/wifi for our office - one for general computers/printers/voipfones etc which are a mixture of hard wired and wifi. Im looking at getting a couple of SONOS speakers and a wireless alarm so wondered if its worth setting up a separate wifi network for them to connect to that cant access the main office network? I'm using Unifi switches/AP's which I'm sure you can set up another guest network via the controller? Edit - also looking at installing CCTV but that will be hardwired, so will I need a VLAN for that?
