Gun cameras are cameras used primarily in aircraft to help measure tactical effectiveness. These cameras are triggered by the firing of a weapon, hence the name.
The use of gun cameras first became common for gunnery training in the 1920s though examples were used during World War I by the British Royal Flying Corps. A special version of the standard Lewis Machine gun was manufactured as a Camera Gun. During World War II, gun cameras were commonly used on operational aircraft to record kills of enemy aircraft. Some of this footage survives to this day and is often the source for stock footage in World War II movies, TV shows or video games.
