A:Answer Taken from the Arlo Support Website: "You can stream simultaneously from a maximum of five Arlo cameras that are connected to a single base station. To start streaming a sixth camera, you must pause one of the active streams. If you have an Elite plan with multiple base stations, you can stream five cameras from each base station simultaneously, up to a theoretical maximum of 15. You might not be able to stream from all five cameras per base station if your WiFi network has limited bandwidth or if you are uploading other files while Arlo is streaming."
