wired network cam & wireless network

ATM I have a combined solwise sar-715 adsl-router/4-port-switch wired to a
couple of PC's and a DLink DWL900+AP in normal AP mode. I also have a
laptop with a wireless pcmcia card. Everything is on the same
192.168.0.0/24 network.

What is the most cost effective way of wireless networking a wired axis
camera into this existing network?

Can I connect the ethernet port on the camera to some wireless network
device and link the camera into the network? If it is possible, will I need
a WAP or an extender or something else? If I need a WAP, what mode would it
need to run in and can it also act as a normal WAP simultaneously so
improving my laptops range? Any info much appreciated.

Thanks,

Dean
