Great overview - thanks @Barry - it will be helpful.
I've a quick question man, you did mention the logitech cam you used - I'm sort of interested - I have a very simple Logitech C160 - with manull focus - and it can be a total PITA !
LOL I got the impression that you had "remote" capability - I guess from some Logitech software - to pan/tilt/focus - and more specifically and importantly to ZOOM the cam..... that would be just ideal for my future plans - I've found the Logitech C270 which I think has these capabilities - just wondering if you can confirm which cam you're using.... because if it has these capabilities I may well opt for the same model as an upgrade. I did notice that it seemed to autofocus at times as well - but I guess that would be capable of being over-ridden ?
I seriously recommend not copying my mistakes. D'oh -
Please make your own, different mistakes, and help us all learn :-)
