Fire almost never starts with open flame — it starts with heat. Overheated bearings, smoldering waste, stressed battery cells: all emit thermal signatures long before smoke or flame becomes visible. Radiometric LWIR imaging detects this build-up directly and works in total darkness and through light smoke, where visible cameras and even smoke detectors respond too late.

Dual-range radiometry covers both early-warning and full-fire scenarios in a single device: a high-sensitivity range (down to -20 °C) resolves small temperature anomalies at their origin, while an extended range up to 650 °C keeps measuring without saturation once combustion begins — supporting responders with live temperature data during the incident itself.

Forest fire illuminating the night — nighttime wildfire scenario
Thermal watchtowers detect wildfire ignition at night and through smoke, when visible systems are blind

Point, line, and region temperature analysis with configurable alarm thresholds keeps false alarms under control: the system triggers on sustained regional temperature rise rather than on every passing vehicle or animal. Low-power cores below 1 W enable solar-powered watchtowers and distributed battery nodes that operate unattended for years.

Typical Deployments

  • Forest & wildfire watchtowers: wide-area 1280 radiometric scanning for ignition-point localization
  • Warehouses & waste bunkers: fixed 640 nodes monitoring smolder-prone storage around the clock
  • Battery & ESS cabinets: miniature cores inside energy-storage enclosures for cell-level thermal runaway warning
  • Industrial yards & biomass storage: pan-tilt radiometric systems covering large outdoor piles

What the Camera Sees: Self-Heating and Storage Risks

Coal stockpiles in an open storage yard
Open stockyards — fixed cameras trend every pile zone, catching self-heating days before smoke
Thermal image of stored bulk material with a hot zone
Stored bulk material in thermal — a developing hot zone shows clear contrast against the surrounding pile
Warehouse racking with stored goods
Warehouses — rack-level thermal supervision responds to warming goods long before smoke detectors can
