You would be better off buying a web cam with Wi-Fi built in. Then you can have the camera dirrectly connect with your access point without the need for a PC in the middle. Then your PC running the software can get the images over the network.
did yu mean an ip cam ? or if you didn't, is there any web cam like this ? can yu give me details? where i can find it? what about its price ?
I mean a web cam that has a Wi-Fi transmitter on it. A fully wireless web cam if you don't count the power courd for the cam.
