ELEVATOR SYSTEM

An elevator system includes a cage, a first capturing device, a second capturing device, and a control module. The cage includes an inner room. The first capturing device is configured for capturing an image of the inner room. The second capturing device is configured for capturing an image of a waiting area outside the cage. The control module receives the images output from the first capturing device and the second capturing device and determines whether or not there is any passenger located at the waiting area and whether or not there is enough room in the inner room to receive the passenger. The control module controls the cage to stop or not to stop according to the determination.
