Seems like a motion activated camera, which is why it pans away when the cat is gripping tightly to the post, then comes back (with the uninteresting part edited out) when the cat decides to come down.
And it does seems like the cat sees the coyote leave before trying to slide down, ultimately giving up on the slide, and dropping to the lawn. He was pretty shaky, but I think he could have stayed longer if necessary.
