Ken, I would love to help you out, but those questions are really hard to answer. I'm just not sure what it is you are asking.
If you need to add a wired camera to a system using a wireless link, yes that is easy. You just need a wireless bridge device at the camera end that is in range of your wireless access point.
As for the VLAN question, you have to make sure that your router and switches support VLANS.
If you're just wanting to do as Jon says, and connect a wired camera via a wireless link, yes, that's easy (well, relatively speaking). I did it in my previous townhome using a $30 router flashed with DD-WRT firmware - just set the router up as a wireless Client, disabled its DHCP server, and then connected it to my WiFi network. Any devices plugged into its LAN ports are then connected to the network over that wireless client link.

If it were me, I would be looking into a couple of the UBNT Nanostation Loco M5 radios. Much less interference on 5ghz bands than 2.4ghz (usually). They are purpose built for this exact purpose and are very cost effective. We have many units operating in the field for many years (3-4) with zero failures and one single reboot ever.
