The invention relates to a system and method for supervising a work area including an industrial robot having at least two de¬ fined security levels. The system comprises at least one visible marking (1 1 , 12) indicating a potentially dangerous region in the vicinity of the robot, the marking having at least one unique fea¬ ture relative to other objects in the dangerous region, at least one camera (9a-d) adapted to repeatedly during operation of the robot capture images of the potentially dangerous region includ- ing said marking, a computer unit (22) adapted to receive said images and to detect changes in the marking based on said im¬ ages, and to decide whether the security level of the robot should be changed based on the detected changes in the mark¬ ing line. |
