Abstract

An opto-electronic apparatus for the monitoring of a protection area which has at least one protection device, which works in a non-contact manner, is described. The protection device, which works in a non-contact manner, has an evaluation unit for the generation of an object detection signal on the intrusion of an object into the protection area. An image detection unit is coupled to the protection device, which works in a non-contact manner, for the detection of an areal or spatial image detection area, with a secondary monitoring area disposed close to the protection area, but outside the protection area, being detected by the image detection unit. The protection device, which works in a non-contact manner, is controllable by the image detection unit.
