Field goal attempts that hit the cameras on field goal posts

[Barney72]

My co-workers and I were having a discussion today. We were watching Monday Night Football and wondered what would happen if an attempted field goal hit the camera mounted on the crossbar of the field goal post and bounced back into the field. Is it considered a missed field goal? Does the kicker get to re-kick? Is the field goal counted because the ball would have sailed over the cross bar if the camera was not there? It would be great if someone could clarify this for us. Thanks!
