Yes you can do this with a Raspberry Pi. The Pi runs a Linux OS and can interface with either a usb webcam or there is a camera add-on which is quite cheap.There is an app Motion which can be configured to do the motion detection and initiate sms or email etc.The latest Raspberry Pi has on-board wifi which is quite helpful.Its a bit fiddly to set up and will turn you into a Linux geek if you aren't one already, but mine gives good results now after quite a lot of messing with it.
