I've thought about these things often (where I live, crime is nothing new). Of course a WebCam is a nice solution, but you can also link an infra-red eye to your serial port, have a daemon running that polls the serial port, if it goes on, shout at them with an MP3 file and send yourself an e-mail.
Now just where to hide the PC and speakers...
