Abstract: The invention discloses a camera comprises a central processing unit (the processor), at least three infrared sensors connected to respective input port of the processor, and a camera head connected to the processor and is controllable by the processor, a rotation mechanism for mounting the camera head and for pivoting clockwise or counterclockwise under control of the processor, and a power supply for providing power to the above mentioned processor, camera head, infrared sensors and the rotation mechanism. All the infrared sensors are arranged circumferentially on the device and a vision scope of one infrared sensor partially overlaps with a vision scope of an adjacent infrared sensor such that the total vision scope covers 360 degrees. Each infrared sensor defines a shooting orientation, and the partially overlapping area of the vision scopes of adjacent infrared sensors also defines a shooting orientation such that the total shooting orientation is doubled.
