1. A surveillance system comprising: a tracking module configured to process first digital image data of a first image frame that is acquired through the use of a first image capturing device to track an object in the first image frame and to generate location information of the object using the first digital image data; a controller configured to map a first point in the first image frame to a second point in a second image frame based on a previously defined correlation between the first image frame and the second image frame, the second image frame being acquired through the use of a second image capturing device, to define a positional relationship between the first image capturing device and the second image capturing device based on the mapping of the first point in the first image frame to the second point in the second image frame, to generate a control signal based on the location information and the positional relationship, and to transmit the control signal to the second image capturing device to control the movement of the second image capturing device to allow the second image capturing device to acquire a third image frame that includes the object; and a detection module configured to process second digital image data of the third image frame to detect a feature part of the object using the second digital image data.
