Is there a Camera policy for NBA Games?

[tbdog]

This is more of a general question and not related to the Spurs. I am in the states for holidays and seeing about 5 NBA games, unfortunately none of them are a Spurs game. They just not playing near any of the cities I am. Looks like I will never see Duncan play. The schedule really sucked for me. The best game is Thunder vs Magic in Orlando, and I am paying about $300 for that game. Anyway, I got a SLR camera with a 250mm zoom, etc. Are you allowed to take these type cameras into NBA games?
