Metrological characteristics of thermal video fire detection systems

We consider the possibilities for designing a new hardware and software system for fire detection, based on combination of video analytics technology and analysis of IR signals from sensors in the mid-IR and thermal IR ranges. We consider the parameters (in particular, the maximum distance for detection of the seat of a fire) for IR sensors based on various photodetectors. As a detector in the visible range, designed for early smoke or open flame detection based on analysis of sequential images of a scene, we suggest using a standard IP network camera.
