What is a tool used for searching for victims in low visibility conditions?

In low visibility conditions, a thermal imaging camera is a highly effective tool for searching for victims because it detects heat signatures emitted by living bodies. This capability allows firefighters and rescue teams to locate individuals who may be trapped or unconscious, even through smoke, fog, or darkness. The camera shows temperatures in different colors, making it easier for responders to identify areas where heat is concentrated, which often indicates the presence of a person.

While standard flashlights can illuminate an area, they do not enhance visibility beyond what the eye can normally see and can be ineffective in smoke-filled environments. Night vision goggles amplify light but are limited to clear visibility conditions and rely on ambient light. High-powered binoculars improve distance viewing but do not assist in distinguishing heat signatures or penetrating smoke. These limitations make thermal imaging cameras the most suitable tool for rescue operations in challenging visibility scenarios.
