Ask how to organize wedding synchronous camera shooting. We have two meeting places, upstairs and downstairs, and we want to get a synchronous camera to play on the projection upstairs and downstairs.
If I understand you correctly, are you talking about broadcasting? So you can see the wedding scene upstairs and downstairs? If so, look at your camera. A single camera is easier said than done, but multiple cameras are a bit difficult. I made a picture to tell you more intuitively. Just asked my colleagues, it can also be realized through microwave relay stations.
