Does interacting with cameras "do" anything?
Every so often I come across cameras like this one:
They open up when I get close, and it seems I need to get within a certain radius to "activate" them. However, once they are "activated" it doesn't seem like anything else happens. Does interacting with them cause any other effect?
These are just checkpoint markers. When you activate one, you'll notice the Borderlands logo appear on screen indicating that your progress is being saved. When you die, you will be resurrected at the latest one you activated.
