How are many seemingly dangerous scenes in the animal world filmed?

Some lenses mount the camera in a controllable and movable position.

In the car, the car can be disguised as a dead tree.

Dry, or a stone, or even a piece of dry feces.

So that animals will not attract the attention of animals. People can control the camera from a distance.

I also like to see the animal world. I watched an episode when I was shooting elephants. There is more than one such camera.
