I am not sure why you think you've configured it to upload 1 image per hour. In your screenshot, the Interval is 180, apparently it means 180 seconds, which is 3 minutes. If your camera is uploading 1 image per 3 minutes, then your camera is right. You just need to change the interval to 3600.
( If it does not let you change the value to 3600, then it is a camera problem. If so, you need to contact the camera manufacturer. )
