For those using it for controlling security camera/webcams and recording images can you link to the software/hardware you're using and how you set things up? Seems a great application for the Pi and I have a B+ just sitting around waiting for me to repurpose it!
I use Motion , http://www.lavrsen.dk/foswiki/bin/view/Motion/WebHome
Very easy to setup and use. You control it via command line so nice and easy to ssh into your pi to play around with it.
There is a you tube video that takes you through it although I have never watched it.
