Don Wheeler, 40, was arrested and charged with possession of an IED and bomb-making material.
He was also charged with possession with intent to distribute crystal meth and heroin.
Jemma Love, 30, was also charged with possessing drugs.
Five rifles and four handguns were recovered from the home, which police said was heavily fortified.
Occupants at the home declined to comment to Action News.
Love was arraigned and released on a summons. Wheeler, on the other hand, was sent to the Camden County Correctional Facility where he remains awaiting his next court date.
