Does anyone know of a gadget that can do something like this? I'm imagining two devices, one that you set in an inconspicuous location that is a motion detector and another that you carry with you that, as long as you are in the range of the detector, will notify you (via a noise or vibration or something) if motion is detected. Any help would be great!
