Optoelectronic surveillance system

The space within a room under surveillance is illuminated by a light source (1) that generates light from a series of point sources. The lighting pattern can be varied by a number of movable apertures at the light source output. Images are obtained by a digital camera (2) that may be operated in syn...

Zusammenfassung:	The space within a room under surveillance is illuminated by a light source (1) that generates light from a series of point sources. The lighting pattern can be varied by a number of movable apertures at the light source output. Images are obtained by a digital camera (2) that may be operated in synchronism with the lighting. The image data is compared with reference data to detect motion or changes.
