An elevator assembly (1) is proposed to comprise an elevator car (3), a suspension traction member (7) suspending the elevator car (3), a drive engine (9) driving a traction sheave (11) for displacing the suspension traction member (7) running along a traction surface of the traction sheave (11), a camera (15) and an image processing unit (17). Therein, the camera (15) is directed towards the suspension traction member (7) for acquiring images of a surface (6, 8) of the suspension traction member (7) during a monitoring procedure for monitoring a deterioration state of the suspension traction member (7). Furthermore, the image processing unit (17) is adapted for processing and analysing the images acquired by the camera (15) during the monitoring procedure for detecting visual deteriorations of the suspension traction member (7) and for generating a signal upon detection of such visual deteriorations. Therein, the camera (15) and the image processing unit (17) are adapted for, during the monitoring procedure, acquiring and processing images of a focus area (18) in predetermined time intervals such as to acquire images of non-consecutive regions of the surface (6, 8) of the suspension traction member (7) while the suspension traction member (17) moves through the focus area (18). Using the camera (15) and the image processing unit (17), deteriorations of the suspension traction member (7) resulting in changes in its visual appearance may be detected and measures e.g. for increasing safety of the elevator assembly (1) may be initiated correspondingly.
