Action camera
Camera sellers usually give you a hard clear plastic box that fits with the camera when you buy it. When they do, you should store the camera in this box every time you are going to film something. This box will have holes, a belt, or a metal rod which you can use for tying it to a person, or screwing it on an object that person wears (usually a helmet). Some kind of these boxes can stop water from coming into it when closed, so you may use them to film under water without breaking the camera as well.
