VLAN and Internet Access

I am setting up a vlan.  I have a ATT Modem I have connected the Netgear switch using a patch cable.  The existing computers are all set up on their own Switch.  We have a Clover Credit Card Machine that is wifi.  When we run their quarterly test, our camera system is causing it to error saying the network is not safe.  My fix was to set up a vlan on a GS108Ev3 switch just to separate our camera system on to its own switch.  However, when I do that, I'm not getting the internet so we aren't able to use our phone app to see the camera system.  Can someone please help me with this issue.
