1. An intelligent control method comprising:
acquiring an image while rotating 360° in one predetermined direction by a camera;
transmitting a radar signal in a coverage covering 360° by using two radar sensors each covering 180°;
receiving the radar signal reflected from a target existing within the coverage;
determining whether a target exists within the coverage based on the reflected signal;
when a target exists within the coverage, determining whether a decision priority for the target existing within the coverage is a person or a vehicle;
determining whether the target has an abnormal sign, while tracking the target in an order based on the decision priority;
when it is determined that the target has an abnormal sign, calculating direction information and distance information about the target; and
rotating the camera in a direction corresponding to the direction information by controlling pan, tilt, and zoom (PTZ) of the camera, and capturing and recording the target showing the abnormal sign by adjusting an angle of the camera to an angle corresponding to the distance information;
when it is determined that the decision priority is a person, operating in a night mode according to a current time;
determining whether two or more targets are detected for a predetermined second threshold time or longer within the coverage;
when two or more targets are detected for the predetermined second threshold time or longer within the coverage, determining whether the two or more targets detected for the predetermined second threshold time or longer within the coverage are identical to previously detected targets;
when the two or more targets detected for the predetermined second threshold time or longer within the coverage are not identical to the previously detected targets, determining the two or more targets detected for the predetermined second threshold time or longer within the coverage as an abnormal condition, and calculating direction information and distance information about the targets; and
rotating the camera in a direction corresponding to the direction information in which the two or more targets are detected for the predetermined second threshold time or longer within the coverage by controlling the PTZ of the camera, and capturing and recording the targets showing an abnormal sign by adjusting the angle of the camera to an angle corresponding to the distance information.
