[Prior Art] Although the general surveillance camera has an autofocus device, when the object to be monitored is a movable object such as a vehicle, an animal, etc., the distance between the monitoring device and the monitoring object needs to be Manually zoom in or zoom out the scene to make the image recognizable. The zoom function is usually only capable of changing the magnification of an object in a linear smoothing manner without being able to switch between different magnifications in real time. Therefore, it is difficult for the same photographic device to quickly and clearly capture objects of different distances, and a single lens can be limited to a certain distance (<20M) for long-distance (>20M). The camera of 20M) cannot be clearly presented. In addition, digital telescopes with long-range shooting capabilities usually do not have an auto-focus device, so the magnification needs to be manually adjusted to capture images, and the digital φ telescope cannot be photographed close due to the limitations of the optical mechanism of the telescope head ( <20M) object. In the case of an application example, a camera installed in a public place such as a street or a cash machine can assist in the search for a security incident. However, in reality, a camera used for this purpose usually has a fixed focal length and a viewing angle, so that the images of key characters or things in the deposited movie are blurred. SUMMARY OF THE INVENTION In view of the above, the object of the present invention is to provide a remote and close distance 0757-A21206ITWF(N2); E0105222; Joseph 5 1280038

For example, the first lens 81 is a telescope head and the second lens 82 is a general camera lens. The first viewing angle is less than 10°, and the second viewing angle is greater than 30°. The viewing angles of the first lens 81 and the second lens 82 differ by more than 20 degrees.
