US Patent 10334437 Secure pairing of devices and secure keep-alive

A method includes sending identification information for a mobile hotspot device from that device to a cloud-based computer processing system, sending identification information for a security monitoring device from that device to an app on a user's mobile device, prompting the user, via the app, to provide the identification information for the mobile hotspot device to the user's mobile device, and sending a pairing request from the app to the cloud-based computer processing system. The pairing request includes the identification information for the mobile hotspot device that was provided by the user and the identification information for the security monitoring device. The method further includes sending a response to the pairing request from the cloud-based computer processing system to the app, and using information in the response to establish a wireless connection between the mobile hotspot device and the security monitoring device.
