Click and hold with your right mouse button and then drag the mouse, and you can use the left / right arrow keys on the keyboard in conjunction with that to speed things up. The close you are zoomed-in, the slower it is. Same with the up / down arrow keys. You should be able to get down to "eye level" with any "people" in the view... You can use that VideoCam button near the upper-right of the window to center on the selected node, and if animated, click that "Play" button next to it...
