thermal ir camera
Surveillance systems such as object tracking and detection systems typically rely on a single modality of color video for their input. These systems work well in controlled conditions but often fail when low lighting, shadowing, smoke, dust or unstable backgrounds are present, or when the objects of interest are similar color to the background, Thermal images are not affected by lighting changes or shadowing, and are not overtly affected by smoke, dust or unstable backgrounds. However, thermal images lack color information which makes distinguishing between different objects of interest within the same scene difficult.
