How is J.A.R.V.I.S. supposed to do that? The helicopters were flying around
the house not inside it, J.A.R.V.I.S. has little power outside the building and he doesn't have magic scanners or something like that, when Stark investigated the temperature peaks caused by Extremis soldiers he had to access to S.H.I.E.L.Ds database and satellites (to which he got pluged-in in Marvel's The Avengers
). You guys remember it's a house, not fortress.
As for Iron Patriot
I imagine they had some kind of identification, even if it was false. Remember that the vice-president was evil all along and when Stark told him about the danger in Air Force One he was the one to explain that the President was safe with Iron Patriot
. I suppose he was the one who gave the confirmation to the Secret Service too.
