 A "Gun camera" may also refer to a video camera mounted on a gun where the camera has a point of aim indicator, typically a reticle in the form of a crosshair or a red dot, that shows in the video where the gun is being pointed.Current gun cameras on hand guns are usually located at the top of the barrel, limiting the officers view.Police officers have changed the design where it is located on the bottom of the barrel but also are attempting to make a gun camera start video taping when an officer draws his or her weapon.
