A few miles up from where I live along the Straight of Juan de Fuca, you will find Race Rocks. Race Rocks is an island with a lighthouse, marine animal life, wonderful ocean views, passing cruise ships, ocean going freighters, and much, much more.
 
They have a great web page which features a number of things, amongst which are cameras that you can watch live and (in the case of camera 5) control from your computer.
 
Keep in mind that Race Rocks is near Victoria, British Columbia - on the West Coast of Canada where it is dark at night.
