Question about multiple cameras

Currently I have an indoor camera at my shop with 2 other people logged into the account so they can monitor it. I am needing to get a second camera to use at a different location. Will I be able to add this new camera to my account and make it accessible? Also I currently have the basic protect plan. Would the premium plan work for this? The premium plan says it works on all devices at one location so I am not sure if it will work with the second camera that will be at a different location.
