Secure works over Wi Fi, but cellular access as a backup is a $5 additional monthly option. The system can also be expanded with options for indoor and outdoor cameras, and compatible Yale electronic locks. While this system is designed to be used for self monitoring through the Nest App, there is also an option for professional monitoring via Brinks Home Security for $29 monthly, or $19 monthly with a three year contract more about that later.
