Most action cameras come with a companion app that allows you to control the camera remotely using your smartphone or tablet. The app usually offers various functions such as changing settings, starting and stopping recordings, and viewing footage in real-time. Some models also offer voice control or remote control using a wearable device such as a smartwatch. This feature is especially useful when the camera is mounted in a hard-to-reach spot or when you need to keep your hands free. Keep in mind that the range of remote control can vary depending on the model and environment.
