Surveillance Method and Camera System Using the Same

A camera system, comprising:

• a base;
• a first camera, disposed on the base, constantly facing toward a first direction, and configured to capture a wide-angle image;
• at least a second camera, disposed on the base, adjustably facing toward at least a second direction, and controlled to rotate around the first camera;
• a display device, coupled to the first camera and the at least a second camera, configured to display the wide-angle image;
• and
• a controller, coupled to the display device, the first camera and the at least a second camera, configured to generate a plurality of control signals to steer the at least a second camera toward at least a second direction according to at least a directional instruction.

A surveillance method, utilized in a camera system, the camera system comprising a controller, a first camera disposed fixedly on abase of the camera system and constantly facing toward a first direction, and at least a second camera disposed on the base and controlled to rotate around the first camera, the surveillance method comprising:

• the first camera capturing a wide-angle image;
• the controller identifying at least an image object in the wide-angle image, where the at least an image object is corresponding to at least a moving object in an environment;
• and
• the controller generating a plurality of control signals to steer the at least a second camera such that the at least a moving object is within at least a field of view of the at least a second camera.
