how to get a camera to side scroll

Hey I've looked at all the suggestions but it still doesn't help me, I want to know how i can get a side scroller camera because my version of unity is the island demo so i don't have the space one so i don't have all the added stuff that you get from the space one.

Can you please tell me where and how i can get a side scrolling camera?

You need to lock the camera rotation.
