Abstract: A surveillance method is utilized in a camera system, wherein the camera system comprises a display device, a controller, a first camera disposed fixedly on a base of the camera system and constantly facing toward a first direction, and at least a second camera disposed on the base and controlled by the controller to rotate around the first camera. The surveillance method comprises the display device displaying a wide-angle image captured by the first camera; the controller receiving at least a directional instruction corresponding to at least a specific part of the wide-angle image; and the controller generating a plurality of control signals to steer the at least a second camera toward at least a second direction according to the at least a directional instruction.

Abstract: Intelligent hotspot connection systems and methods are provided. The intelligent hotspot connection system includes a storage unit, a wireless connection unit, and a processing unit. The storage unit includes a hotspot information database recording at least one property for each of a plurality of hotspots, and a hotspot preference database recording at least one preference inclination, respectively defining a reference weight for the property and signal strength. The processing unit detects the signal strength of the respective hotspots via the wireless connection unit. The processing unit obtains the preference inclination, and calculates a score for the respective hotspots according to the preference inclination, the property and signal strength of the respective hotspots. The processing unit selects and automatically connects to the hotspot with the highest score via the wireless connection unit.
