Why a B/W Optical Sensor instead of standard CCTV camera? The following pictures show clearly the difference in contrast as a result of a filtered spectrum range and in resolution as a result of purpose-selected CCD for the application "smoke detection".   Picture made by specialized Optical Sensor of the „FireWatch“ system (distance to the factory in the foreground ca. 6 km; distance to the small tower at the horizon ca. 18 km).   The same picture made by state-of-the-art CCTV camera (the factory is not clear observable, the tower at horizon line is not visible). The detection results with the b/w sensor of the purpose-designed Optical Sensor of the "FireWatch" system are much higher and clearer and so, the scanned area can be much larger. Especially important for night vision - it gives the “Fire Watch” Optical Sensor a resolution which is 4 times larger than CCTV cameras.
