Is the action camera the new replacement for both digital cameras and video cameras? Given the pace of product development in recent years, we have every reason to suspect that this is the case. The action camera also has many more uses than its predecessor, and in an even more flexible package. As the name implies, an action camera is a camera that can keep up with you, whatever life has to offer. If you want to use the camera to film your running, on the ski slopes or for capturing your next fishing trip, an action camera can be adjusted to your exact needs.
