How did he shoot the program "Survival in the Wilderness"? Was it taken by satellite or was someone following him?

One survivor is a photographer named Simon! There is an episode of Survival in the Wilderness called Behind the Scene, which introduces how the program was filmed and the work of the relevant personnel. Besides Bell, there are cameras, a live recording, a live director and a security expert. These are all introduced by Bell. Many staff members did not introduce them by name, but the number of people who can see them is probably 10.
