Saratoga Race 6 July 29th

Can someone explain how that was a dead heat for place? The live feed was somewhat convincing that the 9 hit the wire first. The photo does not detail who hit the wire because its blocked by the outside horse who won the race. The head of the number 9 was ahead in the photo and the 5 was inches behind. Do the stewards have other sources of information or photos that determine a dead heat that's not privy to the public?
