How Does Thermal Imaging Work ?

Issue Time:2021-04-23

Heat vision cameras or thermal imaging cameras are in fact really heat detecting sensors. 

These thermal cameras are also known by various names including;

  • Thermal Camera

  • Heat Vision Camera

  • Thermal Vision Camera

  • Thermal Imaging Sensor

  • Thermal Imaging Camera

  • Temperature Sensor Camera

  • Thermal Heat Vision Sensor

  • Heat Signature Camera

  • Heat Sensor Camera

Thermal vision cameras make pictures or video from heat, not visible light. 

Heat (infrared thermal radiation) and light are both parts of thelectromagnetic spectrum

However, a camera, which can detect visible light will not see thermal radiation and vice versa.

Thermal cameras detect more than just heat. 

Heat vision cameras detect the tiny differences in heat, even as small as 0.01° Celsius. 

This information is then displayed as various colors on a display, in thermal software or apps.
