A:Answer I read on line in the reviews, that the max is 5 cameras that can be set-up on one system. That's why I didn't understand why they sell a package with 6 cameras. I haven't installed my Arlo cameras yet. I just purchased them a couple of weeks ago. I have to wait until I can purchase a newer upgraded phone to handle this security system.
Here is the answer I found on-line: five Arlo cameras
On the Arlo web client, you can stream simultaneously from a maximum of five Arlo cameras that are connected to a single SmartHub or base station. To start streaming a sixth camera, you must pause one of the active streams.
