Gun cameras are cameras mounted on a gun, used to photograph or record from its perspective. They are typically used on the weapons of military aircraft and operate either when the gun is fired or at the operator's will. Gun cameras are used for training, analysis, or documentation purposes. They're not really a gun, despite sometimes looking like one.

Known real-life examples are:

• Mk. III Hythe Camera Gun
• Type 89 Moving-image Machine-gun Camera
• Katsura Seisakusho Machine Gun Training Camera
