Security system
First Claim
1. A security system comprising a detection means for radiating light or an electric wave to a prescribed area, receiving a wave reflected by an object, and obtaining at least the relative speed and location of said object, an imaging means for picking up image information of the prescribed area, and a moving means for changing the imaging direction of said imaging means, wherein said moving means is controlled according to the relative speed and location of said object so as to direct the imaging direction of said imaging means toward said object.

Abstract
A simple outdoor security system which uses sensors to monitor an area around a building to detect intruders while reducing the number of sensors necessary for ensuring detection accuracy, which has at least a detection means for radiating light or an electric wave to a prescribed area to detect an object, receiving a wave reflected by the object and detecting at least the speed and location of the object; an imaging means for imaging the object; and a means for directing said imaging means toward the object according to the object'"'"'s speed and location detected by said detection means.

12. A security system comprising a detection means for radiating light or an electric wave to a prescribed area, receiving a wave reflected by an object and obtaining at least the relative speed and location of said object, an imaging means for picking up image information of the prescribed area, and a moving means for changing the imaging direction of said imaging means, a transmission means for transmitting an output of said detection means and/or an output of said imaging means, a receiving means for receiving information transmitted by said transmission means, and a display means for displaying received information so that an operator can see it,
wherein said moving means is controlled according to the relative speed and location of said object so as to track said object and pick up an image of said object.

17. A radar device for a security system which is installed outside the building, radiates light or an electric wave to a prescribed area, receives a wave reflected by an object, and obtains at least the relative speed and location of said object,
wherein the beam width of the radar device is 10 degrees or more.
