Refcam
A Refcam is a special type of broadcast point-of-view camera used in sports and worn by a referee or umpire during the game.
Modern systems offer several mounting configurations depending on the sport and production requirements
. The most common are chest-mounted cameras, such as those developed by MindFly and used in professional Soccer, American Football, Hockey,
Baseball, and Basketball in live broadcasts. Other configurations include helmet-mounted cameras, and ear-mounted systems, produced by companies such as Mindfly, Movicom, Riedel and JockeyCam for use by referees in soccer and rugby.
