Instead of fixating on the idea to have the burglar caught on the camera tape, Alex could have easily recorded the burglary on a video recorder at home, since the camera was anyway broadcasting all the images right to the TV from the attic. An obviously intelligent little boy like Alex, being able to handle all that he did during his “mission”, would have certainly thought about that in the first place. There is no way for a video recorder not be found in a house like the one Alex lived in.
