Hi Doug,
I have never put a camera on my Pi. In my setup, the Pi is plugged into my home network, which is distributed from an Apple router on CAT5 cable. It goes to a switch in my study where my workstation and other things plug in, including the Pi over on a small electronics bench. I do have wireless, also from the Apple router, but the Pi is hardwired into its network connection. I would imagine the Pi could be connected through wireless by using a USB wireless adapter, but I have not tried that.
One thing to note about my setup is that I run the Pi as "headless" though a remote login. That means I am using only the Unix command line interface through remote login from my laptop or workstation. (The laptop is on wireless.) No windows interface and therefor I do not run the Mathematica front end or notebook interface. It is probably possible to do that by running the front end on the workstation or laptop and the kernel as a remote kernel on the Pi -- but I haven't tried that. My real interest in this is in using the Pi as the execution machine for hardware control, but being able to develop in Wolfram language on my workstation, and analyze the results of hardware interaction there as well, where more computing power is available. This has thrown me a bit since the Mathematica interface to the Pi does not yet support the B+, but I have all working in C. The only real issue I have now is that I would like to do some real-time work on the Pi, and Raspbian, like other Unix derivatives, is really not a real-time OS. When time permits, I plan on looking into the real-time modifications available.
Best,
David
