Abstract
There is provided an elevator shaftway intrusion detector which utilizes an image detector including a camera for generating a detection field within a zone of detection including the elevator shaft-side roof and floor and an image processing means for generating a detection signal upon an attempted entry. A power supply and switching network are employed for applying power from the power supply to the image detector and processor which are responsive to the detection signal for applying power from the power supply to a detection indicator such as a siren.
