That is near IR. OK for white grass, TV remotes and imaging not quite
red hot cooker hobs as bright, but useless for seeing human body
temperature stand out against a similar coloured but cold wall.
Thermal imaging to see small temperature differences at body heat to
ambient temperature requires expensive germanium optics for longwave
thermal IR and cunning sensor hardware. The kit he had is surprisingly
good.
