Patent ID: 8508595

Claim:
A surveillance camera system comprising: a first surveillance unit located at a first position, the first surveillance unit comprising: a first camera to obtain a first image of a surveillance area; a first driving device combined with the first camera, the first driving device to move the first camera; and a first camera controller to control the first driving device using coordinates of a target position based on initial coordinates defined by a position and an azimuth at which the first camera is installed, and a current direction of the first camera, so that the first camera faces the target position; and an image analyzer to process the first image to identify a moving object in the surveillance area; wherein: the first camera controller is configured to determine target object coordinates in a reference coordinate system corresponding to the identified moving object; and the first surveillance unit sends the target object coordinates directly to a second surveillance unit in reference coordinate system coordinates; the system further comprising: the second surveillance unit that is located at a second position, the second surveillance unit comprising: a second camera to obtain a second image of the surveillance area; a second driving device combined with the second camera, the second driving device to move the second camera; a second camera controller to calculate the coordinates of the target position in camera pan and tilt coordinates based on: initial coordinates defined by a position and an azimuth at which the second camera is installed; a current direction of the second camera; and the target object coordinates in the reference coordinate system coordinates received from the first surveillance unit; wherein: each of the first camera controller and the second camera controller comprises: a coordinate transformer configured to transform the position of an object to be surveilled into the target position in the reference coordinate system; a camera selector configured to select designated surveillance units for surveilling the object to be surveilled from among a further surveillance unit and the first and second surveillance units; and a coordinate transmitter configured to transmit the target position of the object to be surveilled to the selected designated surveillance units in reference coordinate system coordinates; and the reference coordinate system is defined by a global positioning system (GPS).
