One of the systems includes a plurality of security systems, each security system including a secure network coupling a plurality of security devices; a plurality of user devices authorized to send and receive communications associated with a respective security system of the plurality of security systems; and a service provider system configured to manage communications for each of the plurality of security systems with respective user devices, wherein, the service provider system or the user devices are configured to communicate with a push service to send push notifications.

Abstract: Methods, systems, and apparatus, for an infrared detector are provided. In one aspect, an infrared detector is provided that includes a pyroelectric sensor; a controller for receiving a trigger signal outputted by the pyroelectric sensor; a thermopile sensor, wherein the controller starts the thermopile sensor after receiving the trigger signal output by the pyroelectric sensor; and an alarm, wherein the controller controls the alarm to generate an alarm signal in response to a determination that a difference between a current temperature and a background temperature detected by the thermopile sensor is larger than a threshold value and a determination that the areas of the thermopile sensor activated correspond to a human being.
