A method for reporting at least one detected active threat to the homeland security (HS). Each threat is either hidden inside at least one cargo container before transit, or is placed inside at least one cargo container while in transit. Each threat while interacting with its surrounding generates a unique threat signature. The method comprises; (A) substantially continuously probing each cargo container; (B) detecting at least one threat signature;—(C) processing each detected threat signature to determine a likelihood of at least one threat to become a threat to HS;—(D) identifying at least one said container that includes such threat to HS;—(E) reporting to at least one Homeland Security Monitoring Center (HSMC) that at least one container includes at least one such threat to HS; and receiving instructions from at least one Homeland Security Monitoring Center (HSMC) how to eliminate at least one such reported threat to HS while in transit; and—(F) using robotic means to eliminate at least one such detected threat to HS.
