When I insert my house key in the door, an LCD will show the faces of those presently inside (unless someone left/entered through a window). Cameras on both sides of the outer doors identify and update the population. Should be disabled before surprise parties.-- FarmerJohn, Apr 17 2005 Outdoor Population Gentleman_20Caller_20ID [theircompetitor, Apr 17 2005] surprise parties = burglars?-- po, Apr 17 2005 Damn, Uncle Spencer is over again? Let me run some errands-- theircompetitor, Apr 17 2005 Do you have a very complex household, FJ?-- Basepair, Apr 17 2005 Uh, no Sir.-- FarmerJohn, Apr 17 2005 When we have RFID locks on our homes (like the Honda Prius car has) then we would know who was in or out without cameras (I seem to be on an RFID kick). Two sensors either side of door so approach or withdrawal are detected.-- Widgit, Apr 17 2005 [+] neat one.
