What fill light does the camera use?

Many cameras are worn, but they really can't. His design purpose is to provide illumination for the focal length direction of the camera in dark environment. However, if your environment is really dark, its effect is very bad. Once I made a video with a friend, and it felt like.

There are ghosts on the screen, but usually the lights can't be turned off. He uses the camera's own light sense as a switch, so sometimes it stays on at night.

I hope you are satisfied.
