The invention discloses a centralized management method of network cameras and relates to the management method of the network cameras, and the method comprises the following specific steps: 1) writing an electronic tag for each network camera, and realizing automatic distribution of address information of all the cameras through DHCP protocol; 2) separating control logic of the whole system from service logic and further improving the capacity and the reliability of the whole system; and 3) realizing the marking of the network cameras through position information by being combined with the GIS technology. The centralized management method of the network cameras has the benefits that as the centralized distribution of addresses of the network cameras is realized by adopting the electronic tags and being combined with the DHCP protocol, the centralized management method of the network cameras can reduce the deployment difficulty of the whole system; the realization way of separating the control logic from the service logic can improve the capacity and the reliability of the system; and the application of the GIS technology can improve the using convenience of users.
