I'm currently adding a bit of security to my house by buying some
cheap
wireless PIR sensors and receivers from
http://www.screwfix.com/app/sfd/cat/cat.jsp?cId=101495 , interfacing a
PC

What are you doing for the data logger?

I use the PC's serial port to monitor the state of the wireless receivers,
Java to poll the port, send the alerts and control the webcams, and a
database to log the data. It's very DIY.


So you have your PC on all the time. I'd definitely want to avoid that if
possible.
