Wireless communication between devices

Hi there

I'm just learning electronics and am building some silly starter projects. In particular I'm building a diy home alarm. I don't want wires every where and want the components to be wireless.

My question is: what options should I look at for wireless communication between say a motion detector and the main alarm? I've seen on sparkfun they have 2.4 ghz transcievers and blue tooth parts. Is this what I would use? Ideally I would get them as cheap as possible and have say a transmitter on the motion detector and a reciever on the alarm.

Any input or available options would be appreciated. Thanks!
