The invention relates to a method for monitoring a lift car (3) by means of at least one optical sensor (9) which functions in a stable manner even if a plurality of objects are detected and is characterized by a low susceptibility to errors. In accordance with the invention the at least one optical sensor (9) detects image data in a monitoring region of the lift car (3), wherein the detected image data is compared in an evaluation device (6) with at least one reference image of the monitoring region in order to carry out the following steps: - detecting the entrance of objects into the monitoring region; - detecting the departure of objects from the monitoring region; wherein - a concealed record is activated if the object is no longer detected by the at least one optical sensor (9); - the concealed record is deactivated if the object is detected again by the at least one optical sensor (9); wherein an alerting procedure is triggered if - a data object is not deactivated within a defined period of time following its activation and the data object does not have an active concealed record.
