WHAT'S THERMAL IMAGING TECHNOLOGY

The spectrum of visible light is actually only a small part of a large band of detectable signals, or waves, that travel through matter. The electromagnetic spectrum contains radiation from various invisible wave types, each with a unique wavelength. Thermal radiation is one of these, featuring longer wavelengths than those of visible light, and is therefore generally invisible to the human eye. 

Any object with a temperature above absolute zero emits a detectable amount of radiations. The higher an object’s temperature, the more radiations are is emitted. Taking advantage of the temperature differences between objects, thermal cameras make the invisible thermal radiation “visible” in the form of heat zone images.

ADVANTAGES OF THERMAL IMAGING

Unrivalled Adaptability

The image reproduction of thermal cameras is not affected by lighting conditions - either extremely low light or even no light at all. And compared with imaging with visible light, thermal cameras are much less impacted by weather conditions such as fog, smog, rain and snow, so that they can work in virtually any environment, anytime.

 

Video Content Analysis

Thermal imaging has an intrinsic advantage for video content analysis (VCA) – it renders objects with clear outlines that stand out pretty well against the background, even at great distances. Users can easily set up VCA rules to detect actions such as line crossing, intrusion, region entrance, and region exit with high accuracy.

APPLICATION SCENARIOS OF THERMAL IMAGING

Perimeter Defense

  • Superior Environmental Adaptability
    Thermal products are capable of capturing images all day and night, regardless of environmental factors such as darkness, bright light, backlight, fog, and haze.
  • Extended Distances
    Compared to optical cameras, thermal detection covers much longer distances and requires fewer devices to install.
  • Better Visuals
    With thermal cameras, you can easily discover objects and potential risks otherwise invisible to normal cameras. In addition to thermal images, the built-in visible-light module can provide supplementary recorded evidence – lowering costs for installation.
