The invention discloses an unmanned reconnaissance/attack integrated networked safety defending system and a control method thereof. According to the system of the invention, through setting a plurality of reconnaissance/attack integrated nodes in a guarding area, through a manner of combining photoelectric monitoring and radar monitoring, a target which enters the guarding area is monitored, andfurthermore four denial warnings are transmitted from far to near to the reconnaissance/attack integrated nodes, thereby effectively controlling the border, reinforcing safety protection for the offshore stationed places of China and realizing management intelligence of the guarding area, satisfying requirements of real-time and diversified disposal means, professional investigation and evidence obtaining and simple scheduled inspection insurance. The unmanned reconnaissance/attack integrated networked safety defending system and the control method thereof have advantages of effectively reducing working intensity of frontier worriers and safety personnel, improving real-time monitoring and controlling ability to a blockade zone, and effectively preventing a great loss of an our key defending area caused by a flaw of an our defense line.
