1. An apparatus for safeguarding a monitoring area, in which an automatically operating machine is disposed, the apparatus comprising:
a sensor unit for monitoring the monitoring area, wherein the sensor unit comprises a camera system for producing images of the monitoring area; a configuration unit for defining at least a first protection area and a second protection area; and an evaluation unit for triggering a safety-related function; wherein the first protection area is at a first distance from the machine and the second protection area is at a second distance from the machine, the second distance being larger than the first distance, wherein the sensor unit monitors both the first protection area and the second protection area, wherein the evaluation unit is configured to analyze the images produced by the camera system so as to evaluate both (i) whether a machine element of the machine enters the first protection area as well as (ii) whether a foreign object enters the second protection area, and wherein the evaluation unit is further configured to trigger the safety-related function if it is detected that a machine element of the machine enters the first protection area and/or a foreign object enters the second protection area. |
