How to view videos from iPhone to Mac?

I recently got a mac & I imported videos from my camera roll from my iPhone into the mac. Now, I tried to do it again but only pictures from my Photostream pop up. I've tried looking into the Photos and Image capture but my Camera Roll still doesn't pop up. Help (also I don't really want to download anything to view it )

You can use iPhoto to import the videos from your iPhone to Mac. IPhoto is built-in your Mac system, you don't need to download or install anything.
