Colin you are correct, climbing over or through is used. The XXX laser measurement sensors/systems are particularly suitable for use as curtain detectors by using them in front of the objects to be protected, or as intrusion detectors for walls and windows.
They can be used indoors and outdoors for the vertical monitoring of fence systems or for the horizontal monitoring of flat open areas such as lawns, courtyards, paths and drives. They are also suitable for monitoring roofs and ceilings.
People or objects who enter the detection range of the laser scanner will be reliably detected. Interruptions with or without tools are also detected independent of the distance, as are climbing over or climbing through. The sensor also accurately detects people who are walking, running, crawling over an area, or vehicles that are driving over an area.

Have I missed previous questions on this topic? You appear to know a lot about the specific application (data sheet, etc.) that is not indicated in the question. As far as I can see, there are no clues here regarding the nature of the "Erfassungsbereich"; it could be a warehouse, the protected space around a machine tool, a museum, a bank vault, a military facility, the outer perimeter of a lion/crocodile enclosure at the zoo... Whatever the application, something could potentially be climbed over, or through, and that is what the laser system is intended to prevent.

This is a laser system to protect objects and the sensors are also used (acc. to the datasheet) as "Durchbruchmelder" fuer Waende und Fenster un Dach und Deckenflaeche. Meaning here, an "object" (tool) would be used to break through the Wand or Dach. Theft protection or intrusion protection. Die Eingriffe mit und ohne werkzeug werden entfernungsabhaengig ebenso detektiert wie auch Ueberstiege oder durchstiege...since the sensor beam has a wide range and detects such non-permissible passages.
