Thermal security cameras have been known for nighttime applications under low or zero lighting conditions. When conditions are ideal, thermal cameras allow a person to "see" what the eye cannot, even in complete darkness.
However, outdoor conditions are rarely ideal:
As a result, many thermal cameras are unable to provide important details and situational context for making quick and effective security decisions. The key for the successful use of outdoor security thermal cameras is to provide a good clear image day and night. This is achieved with image processing that adapts to dynamic outdoor conditions. when proper technology is applied, necessary daytime details can be achieved without augmentation from visible cameras, returning the value of thermal imaging for outdoor twenty-four hour use.
