Unfortunately what you're asking for isn't possible with a simple circuit.

However there may be a simpler way to get the same result.  Explain the problem and maybe some of the smart folks around here can come up with a solution.

What exactly are you trying to do?  Do you want to be notified wherever you are when someone (or something) passes a motion detector?  Do you want a record of when someone used an IR remote control?  Do you want to trigger a door lock, jack up someone's phone bill, or something completely different?
