A scalable dual mode monitoring system according to the present invention is configured to communicate using RF communication channels wherever possible for better range and less battery power consumption. When the system uses 2.4 GHz FHSS RF technology, the system coverage could reach a range of 250 meters line of sight; standby current goes down significantly as compared to that of solely using Wi-Fi communication channel; time to get video streaming is reduced when compared to systems that solely use Wi-Fi communication channel because RF communication channels allow for better and faster synchronization; system set-up via RF link is easy without pairing or any setup and requires simply plug and play when using RJ45 cable connecting to router from the hub.
