Some thieves and unsavory individuals have learned that you can momentarily disable some CCTV cameras by shining bright lights directly at the camera lens. HLM is one of several methods developed to combat this threat.  When HLM is active it will mask the source of the bright light with a dark shape, thus allowing the area to the side of the light source to be viewed and recorded. People who think they are concealed in a halo of hazy white light will be revealed.
