I am not sure if this is the correct place to post, but I couldn't find anywhere better.

I am looking for a webcam/movie cam and this site seems more addressed to still images, but ...

I am looking for a small, rugged web-cam which can be hand-held or perhaps head-mounted (failing that I can settle for a tripod mount, but I need portability).

It must have its own IP address so that anyone can view its video stream from a web browser.

I would prefer 2 way voice communication too.

Encryption of data is nice, as is compression (H.264).

Maybe also remote control, like causing it to zoom from the browser.

Does anyone have any suggestions, even suggestions of somewhere else to look?

Thanks very much in advance.
