Looking for wireless video web server

Hi
Since 2 days now, i'm looking for a simple and easy to config solution for a
remotely accessible wireless cameras network (let's say 4 wifi cameras and 1
wifi receiver with embedded web video server).
All that i can find is standalone ip cmaeras with web server integrated or
analog video web server.
The only one which seems to meet my needs is www.smartvue.com, but it's too
expensive.
Can anyone point me to some urls where this kind of product could be found ?
TIA
Christian
