A monitoring device () for spatial areas () includes emitters () that emit radiation pulses that are reflected by objects located within the spatial areas () toward receivers (). The receivers () are connected to a run time determining unit () with whose aid a distance image of an object within the spatial areas () can be generated. A selection unit () evaluates the distance images and generates a detection signal at an output () when predetermined distance values occur in the distance images.
