This bullet-housing thermal camera stands watch against flame at outdoor sites.

Merging thermal and visible sensors, this bullet-type flame detection camera keeps working outdoors down to -40 °C behind an IP67 casing. The 4 MP CMOS sensor supplies the color image while the uncooled VOx detector supplies the heat map.
