Abstract
A spatial area is monitored by means of at least a first and a second image recording unit that have a common viewing area. At least one virtual protection zone is defined within the common viewing area. A first and a second image of the spatial area are recorded by means of the first and a second image recording unit. The images are compared with one another in order to identify mutually disjoint image regions in the images. An alarm signal is generated when a disjoint image region covers the virtual protection zone.
