sentences:  RaceCam
  
  RaceCam is a video camera system used primarily in motor racing, which uses a network of car-mounted cameras, microwave radio transmitters, and relays from helicopters to send live images from inside a race car to both pit crews and television audiences.Although a vehicle-mounted 16mm motion picture camera was used once in 1973, the technology was first developed in the late 1970s by the Seven Network in Australia, who introduced it for the 1979 Hardie-Ferodo 1000 endurance race at Mount Panorama in Bathurst, New South Wales with Sydney-based driver Peter Williamson able to give commentary from his Toyota Celica.
