Lily's sacrafice

In regard to the question, how does Dumbledore know that Lily was 
killed after James, there may have been a device in the Potter's home 
that kept them under survailence with Dumbledore.  Keeping in mind 
that Moody has devices such as his foe glass, it is very likely that 
there are devices we the audience don't know about yet (such as JKR's 
comment that Harry will come across something better than the 
internet).Perhaps something was planted in their home.  We still have 
3 books left to explore the wonders of the WW, so there is likely to 
be an explanation.  Hopefully, we will get the entire scoop in book 
five, as Dumbledore says  "Sit down Harry, I'm going to tell you 
everything". I do hope he means everything!
