The Mount's camera is not on their website yet this season and the other address I used to be able to use was discontinued a few months ago. There is presently no way to view that camera that I can find. Their season starts later in May so I assume the camera will reappear by then.
For now you can view the Mount's dock at the Weirs through the Flightcraft webcam. You can even watch the live stream as you wait for the Mount to pull in for the first time:
