Early Fire Detection

Our early fire detection products ensure an extraordinary high level of identification accuracy. Therefore, typical false alarms caused by environmental factors are distinguished by combining advanced sensors and intelligent algorithms. The main benefits are enhanced security and huge costs savings.

CUSTOS is a universal camera-based surveillance concept working in the NIR range for a variety of applications. The fire and smoke detection system CUSTOS, developed by m·u·t, consists of a NIR camera and NIR illumination units. Both can be applied in multiple combinations as multi-criteria detectors.

CUSTOS has major advantages compared to common fire and smoke detectors by using NIR filtered CCD sensors. It is a tremendous support for situation judgment and fire fighting. Initially developed for cargo compartments of aircrafts, the technology supports many more applications such as:

Canteen kitchenCasting housesEngine test benchesStorage roomsPetrochemistryMachine rooms and energy housesCruise ships and ferriesWith special software: access control and motion sensor 
 

The image acquisition takes place in a wavelength range invisible for the human eye. The image is transferred into a black and white video. Areas resulting in an alarm can be highlighted with certain colors. In the example the reflection of a fire behind the container can be seen on the wall. There is no direct view onto the fire. The highlighted image simplifies the situation judgment immense. For the detection of aerosols, the skilled observer can decide whether it is smoke, fog or dust based on the development over time.
 
Based on the video images precise localization within the 3D room is possible. In case of a known topography the distance to the observed surface can be determined, as the direction of each pixel within the viewing angle is known. With a fixed installation of the surveillance system only one camera is necessary for an exact localization. This is mandatory for a targeted situation judgment and initiation of fire fighting activities. Is the fire source detected by two cameras at the same time, the precise localization is possible without further information. Therefore localization in three dimensions is possible even with moving objects within the surveillance area when multiple cameras are used.
