There, shielded from most sources of contaminating radiation, researchers have spent more than a year's worth of time looking for
flashes of light emanating from WIMPs striking xenon nuclei.

He said under nighttime and low -
light conditions, there is insufficient
light for a conventional camera to capture facial imagery for recognition without active illumination such as a
flash or spotlight, which would give away the position
of such surveillance cameras; however, thermal cameras that capture the heat signature naturally
emanating from living skin tissue are ideal for such conditions.
