The NAOS system offers a unique tool for effective and fast-response fire management. This system enables early fire detection which leads to timely localization of the fire and prevention of its further spread.
This system is a special modification of the stationary and mobile versions of the electro-optical surveillance systems provided by EVPU Defence a.s. It can be placed on masts, towers or other elevated places. Apart from the above mentioned usage, it can be used also as one part of the complex solution of protection of the areas of interest, such as border areas, military bases, airports and harbours. Due to its capabilities, it can be applied not only to the military and police applications, but also in the civil sector.
Important part of this system is special software enabling fast and effective fire detection. The principle of the detection is based on the work with isotherms, which are optional sections in the thermal imaging display. Whilst monitored they have the same temperature range. The temperature range and the limits for the monitored area are defined by the operator pursuant to the specific needs and nature of the monitored area.
The picture from the thermal imaging camera is transferred into an evaluation computer and with the help of the software it is transferred into greyscale. The fire alarm is launched when the temperature specified by the isotherm, exceeds the operator´s pre-defined temperature limits for particular amount of monitored locations. The visual alarm can be accompanied by a sound signal as well.
At the request of the customer, the company EVPU Defence is able to supply the NAOS system with various types of cameras and provide the fire detection up to the distance of about 16 kilometres.
