<p>The optoelectronic protection device has at least one camera (3) for recording images of the surveillance area, coupled to an evaluation device (4), for processing the obtained images and for initiating a reaction upon detection of a given event. At least one radiation source (2) is positioned adjacent the camera within the camera housing, the surveillance area enclosed by a reflector (5) with coded reflector segments (5a,5b), for reflection or non-reflection of a defined wavelength range. An Independent claim for a surveillance area monitoring method is also included.</p> |
