Infra-red camera (IR) which is now used by the fire department need a lens that can be blinded by a huge fire. IR camera cannot 'see' objects or people behind the fires because it requires a zoom lens that concentrates the light to form the image sensor so that the necessary technology that can be used by emergency response personnel and firefighters on the fire to see through smoke without being blinded by the fire. Infra-red holography can have more benefits than current imaging camera is used to search for people trapped in a burning building. Holography application can record the body moves and monitor respiratory and cardiac activity.
