Former England Under-21 international Camp, who was born in Derby but qualifies for Northern Ireland through his grandfather, was cleared by FIFA for selection last month.
The 26-year-old replaces Linfield's Alan Blayney in the 23-man squad to for the Euro 2012 qualifiers against Serbia and Slovenia on March 25 and 29 and the Forest man could now be pushing for a starting place with Inverness' Jonathan Tuffey.
Camp earned five caps for England Under-21s, including the first match at the new Wembley against Italy.
