As to cameras seeing "much clearer" than the human eye, they are actually so different that they are very difficult to compare. The human eye takes in a much broader picture than a camera, while the camera may bring in more detail in its smaller field of view. This is because the human eye is built so as to see all the bushes a lion might hide behind well enough to catch the suspicious ones, not a really clear view of a lion too far away to be a threat.

Additionally, the human eye was "designed" by a mindless process and honed over millions of years by that process, one that quits whenever the eye was "good enough", while a camera is made to precision in a factory and designed by an intelligent being which can use metal, glass, and plastic rather than having to grow everything from the ground up and going for a pre-determined end goal of making it better.

As for seeing farther, the zoom lenses in/on a camera are like a telescope. This gives them an advantage when focusing on things at a distance. Human eyes have one lens with variable focal length, not a telescope.
