Abstract
An optoelectronic security system includes a plurality of light transmitters in a light grid arrangement for the transmission of light signals into a monitored zone, at least one spatially resolving light reception unit for the reception of the light signals transmitted by the light transmitters and a read-out circuit for the reading out of the signals of the at least one light reception unit. The optoelectronic security system has an evaluation device which is configured such that it can split the surface of the at least one light reception unit into at least two processing regions in dependence on a predetermined selection criterion and can further process the signals of the at least two processing regions differently.
