Panasonic BL-C230A
Pros: Does it all and the ONLY manufacturer (Panasonic) with a timer based, single FTP image filename upload function (webcam in a box). PLUS can be configured for direct public viewing with no username/password requirements. A webmasters go-to toy and only choice for webcam updating plus web friendly public access as well
TRENDnet Wireless-G IP Camera
Pros: Great camera. Pan is fast and pretty quiet. Love the options available. There are also iPhone apps that can view and control this camera. Very nice for those of us that also use it as a baby monitor.
TRENDnet Wireless-G IP Camera with 2-Way
Pros: Good picture/video. Works fine over a slow (1.5Mb) connection. Camera software/built-in webserver is fairly intuitive. I haven't installed the camera app. that came with it, as I'm using it for a wireless web-cam atm.
