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.


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.

  • 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.

  • Temperature Anomaly Detection
    Thermal cameras can detect abnormal temperature in key areas and trigger alarms in the first place to prevent fires.
  • Dynamic Fire Detection
    If an area’s temperature is undetectable or fire already starts, thermal cameras can also detect fire at early stages by a dynamic fire detection algorithm.


Perimeter Defense
  • Heat Distribution Display
    Thermal cameras transform invisible infrared radiation of target objects into a visible, heat-distribution image in real time, which helps users locate problematic areas easily.
  • Non-Contact Temperature Measurement
    By evaluating the intensity of infrared radiation emitted from objects, thermal cameras perform non-contact temperature measurement. Users can keep their operating equipment up and running throughout the inspection process, which helps technicians work safer and more efficiently.
