There is camping near (<20 miles)the major diving ports of Cape Hattras, Morehead City and the Wilmington area (Carolina Beach and Wrightsville Beach). I personally do not recommend camping at the beaches during most of the diving season. I am assuming by camping you mean in a tent, a rec vehicle with A/C is a different matter. Between the heat, the humidity and the bugs it can be very miserable and a good nights sleep is needed to enjoy NC diving. A room with a hot shower and A/C is real important to me due to the conditions that often accompany NC diving. As O-ring had indicated, NC wreck diving is a lot more intense than some are prepaired for. A 50% blowout rate is not unheard of. The trips are 1 to 3 hrs out with a 1 to 2 hr SI between dives in 90+ deg F. There are days when the seas are flat and lovely but more often you will be diving in 4 to 6 ft seas. Odds are at least 1/3 of the divers will be sea sick. Don't get me wrong, there are lovely days with flat seas, gin clear water and the wrecks are covered with marine life which makes the trips worth the ride, but I see too many divers, esp new divers, that are not prepaired to handle the conditions we often have, this is not Florida or Caribbean diving. I will be happy to give you more on the camping sites if you want.
