Game camera and trail camera are the same. Another term for them is a 'remote camera'. The wordplay here is based on the functionality of the camera. A game camera is a trail camera that is used to keep an eye on animals, mainly related to wildlife photography. Therefore, a game camera is a rugged and weatherproof camera that is designed to be used outdoors, and sustain itself without supervision. A remote camera is a camera that can be set to click pictures remotely. These are mainly used for sports photography and security purposes. Simply put, all game cameras are trail cameras and all trail cameras are remote cameras.
