US Patent 7823703 Image monitoring apparatus for elevator

In an image monitoring apparatus for an elevator, an image recording unit records an image in a car photographed by a camera, and monitors based on the image in the car whether or not there is a violent behavior of a passenger in the car. The image recording unit makes a recording density of the image in the car higher than usual when the violent behavior of the passenger in the car is detected. The operation control unit homes the car on a predetermined floor when the violent behavior of the passenger in the car is detected by the image recording unit.
