BW-DC series is a self-developed intelligent gain control algorithm, detail hybrid enhancement algorithm and 3D noise reduction algorithm, 10 kinds of pseudo colors, capable of fire point detection, high temperature detection, and detection of regional intrusion, crossing the boundary, and entering/leaving the area. It supports 1 line temperature measurement, 9 frame temperature measurement, 10 point temperature measurement, 2 irregular areas, 2 circular area temperature measurement, full screen highest temperature, lowest temperature positioning, etc. It supports 2 alarm inputs and 2 alarm outputs. It is used in industrial places such as the power industry, chemical disposal centers, combustible warehouses, petrochemical plants, coal mines, etc., where real-time temperature monitoring of key locations is required to prevent dangerous events.
