Abstract
A device having an image-providing sensor, hereinafter designated as “image sensor,” operating in the visible and near-infrared range, an thermal image-providing sensor, hereinafter designated as “thermal-image sensor,” operating in the thermal radiation range and having a lower resolution than the image sensor, and an electronic evaluation system. The evaluation system determines whether one or both of the signals generated by the sensors are used for determining whether an alarm condition exists. As a result, the detectability of low-contrast objects is increased, the false alarm rate is reduced, and object classification is made possible.
