The system works pretty well until you add more cameras. Then the hardware isn't capable of keeping up with the data volume. It isn't possible anymore to see video quickly, for example. A camera will alert - but you have to wait a long time to actually see the video. It is still recording but it's too slow. Stop adding these "impress your friends with this stupid doorbell sound" link IN THE SECURITY SCREEN. It's an ALARM SYSTEM not a stupid social network.
